Variation in pelvic radiography practice: Why can we not standardise image acquisition techniques?Snaith, Beverly, Field, L., Lewis, E.F., Flintham, K. 05 July 2019 (has links)
Yes / Pelvic radiographs remain an essential investigation in orthopaedic practice. Although it is recognised that acquisition techniques can affect image appearances and measurement accuracy, it remains unclear what variation in practice exists and what impact this could have on decision making.
Method:
This was a cross sectional survey of UK radiology departments utilising an electronic tool. An introductory letter and link was distributed. Responses were received from 69 unique hospital sites within the specified timeframe, a response rate of 37.9%.
Results:
There was no consistent technique for the positioning of patients for pelvic radiographs. The distance varied between 90 and 115 cm and 10 different centering points were described. In relation to leg position, the feet are usually internally rotated (65 of 69 [94.2%]). Only 1 teaching hospital (1 of 69 [1.4%]) uses a weight-bearing position as standard.
Orthopaedic calibration devices were not in routine use, with only 21 using on pelvic x-rays (30.4%). Further, the type of device and application criteria were inconsistent.
Conclusions:
To our knowledge this is the first study to directly compare radiographic positioning across hospital sites. Our data demonstrated marked variation in technique for pelvis radiographs with associated implications for clinical decision making. Research is required to determine the standard technique and quality outcome measures to provide confidence in diagnostic interpretation particularly for serial radiographs. / College of Radiographers Industry Partnership Scheme (CoRIPS).

The immobilisation and restraint of paediatric patients during plain film radiographic examinationsGraham, P., Hardy, Maryann L. 05 March 2020 (has links)
No / The immobilisation and restraint of children to facilitate radiographic examination is a controversial issue that has been relatively ignored by radiography research. The aim of this study was to begin to fill this gap by providing a description of restraint used in a limited number of clinical sites in order to highlight any perceived need for training, policies or guidelines in the use of child immobilisation and restraint.
Methods: A cross-sectional survey design using a postal questionnaire was adopted. One hundred and sixty-seven questionnaires were distributed to radiographers employed within six hospital Trusts.
Results: A response rate of 83.2% (n=139/167) was achieved. Ninety-three percent (93.5%, n=130/139) of respondents indicated that restraining techniques were used although only 19.2% (n=25/130) had received specific training in safe restraining techniques and 7.9% (n=11/139) in distraction techniques as an alternative to restraint. A need for further guidance and support for clinical staff was evident with 73.3% (n=74/101) of respondents identifying a need for specific guidelines and 84.6% (n=110/130) indicating that further training opportunities were required.
Conclusions: The use of restraint in paediatric plain film radiography is an apparently widespread practice and support for clinical radiographers through the development of training opportunities and practice guidelines are seen as essential in order to promote high quality paediatric radiography practices.

Improving wrist imaging through a multicentre educational intervention: The challenge of orthogonal projectionsSnaith, Beverly, Raine, S., Fowler, L., Osborne, C., House, S., Holmes, R., Tattersall, E., Pierce, E., Dobson, M., Harcus, J.W. 05 August 2020 (has links)
Yes / In relation to wrist imaging, the accepted requirement is two orthogonal projections obtained at 90°, each with the wrist in neutral position. However, the literature and anecdotal experience suggests that this principle is not universally applied. Method: This multiphase study was undertaken across eight different hospitals sites. Compliance with standard UK technique was confirmed if there was a change in ulna orientation between the dorsi-palmar (DP) and lateral wrist projections. A baseline evaluation for three days was randomly identified from the preceding three months. An educational intervention was implemented using a poster to demonstrate standard positioning. To measure the impact of the intervention, further evaluation took place at two weeks (early) and three months (late). Results: Across the study phases, only a minority of radiographs demonstrated compliance with the standard technique, with an identical anatomical appearance of the distal ulna across the projections. Initial compliance was 16.8% (n = 40/238), and this improved to 47.8% (n = 77/161) post-intervention, but declined to 32.8% (n = 41/125) within three months. The presence of pathology appeared to influence practice, with a greater proportion of those with an abnormal radiographic examination demonstrating a change in ulna appearances in the baseline cohort (p

Career intentions, their influences and motivational factors in diagnostic radiography: A survey of undergraduate studentsHizzett, Kayleigh, Snaith, Beverly 01 April 2022 (has links)
Yes / The choice of career and speciality can be a complex process. It is unclear what influences career decisions within undergraduate radiographers and whether the curriculum provides sufficient support. Methods: An online cross-sectional survey was undertaken. All undergraduate diagnostic radiography students within one UK higher education institution were invited to participate. Questions were related to anticipated career choice, motivational factors and influences. Results: The response rate was 67.6% (90/133). The most popular specialist area for career preference was general radiography. The top three motivational factors were work life balance, career development and job satisfaction. The most influential factors on career choice were clinical placements, radiographers on placements and formal teaching. Career guidance was predominantly sourced from the personal academic tutor and was informed by role models. Conclusion: Radiography academic teams and clinical placement providers must work together to ensure that students have access to high quality placements across specialities. The experiences received during undergraduate training are important in specialty choice. Implications for practice: Career guidance is essential and should begin as early as possible. Clinical and academic radiographers need to appreciate the influence they have on students future career plans. / The form of the authors names on the accepted manuscript are: Hackett, Kayleigh and Snaith, Beverly.

Five years of #MedRadJClub: An impact evaluation of an established twitter journal clubBolderston, A., Meeking, K., Snaith, Beverly, Watson, J., Westerink, Woznitza 01 April 2022 (has links)
Yes / Twitter journal clubs are a relatively new adaptation of an established continuing professional development (CPD) activity within healthcare. The medical radiation science (MRS) journal club 'MedRadJClub' (MRJC) was founded in March 2015 by a group of academics, researchers and clinicians as an international forum for the discussion of peer-reviewed papers. To investigate the reach and impact of MRJC, a five-year analysis was conducted.
Tweetchat data (number of participants, tweets and impressions) for the first five years of MRJC were extracted and chat topics organised into themes. Fifth anniversary MRJC chat tweets were analysed and examples of academic and professional outputs were collated.
A total of 59 chats have been held over five years with a mean of 41 participants and 483,000 impressions per hour-long synchronous chat. Ten different tweetchat themes were identified, with student engagement/preceptorship the most popular. Eight posters or oral presentations at conferences, one social media workshop and four papers have been produced. Qualitative analysis revealed five core themes relating to the perceived benefits of participation in MRJC: (1) CPD and research impact, (2) professional growth and influencing practice, (3) interdisciplinary learning and inclusion, (4) networking and social support and (5) globalisation.
MRJC is a unique, multi-professional, global community with consistent engagement. It is beneficial for both CPD, research engagement, dissemination and socialisation within the MRS community.

There's nothing plain about projection radiography! A discussion paperMussmann, B.R., Hardy, Maryann L., Jensen, J. 15 June 2023 (has links)
Yes / Objectives: Unlike the technological advances in cross-sectional imaging, the adoption of CR and DR has
been relatively overlooked in terms of the additional radiographer skills and competences required for
optimal practice. Furthermore, projection radiography is often referred to as basic, plain or other words
suggesting simplicity or entry-level skill requirements. Radiographers’ professional identity is connected
with the discourse expressed via the language used in daily practice and consequently, if the perception
of projection radiography is regarded as simple practice not requiring much reflection or complex
decision-making, apathy and carelessness may arise. The purpose of this narrative review was to raise
projection radiography from its longstanding lowly place and re-position it as a specialist imaging field.
Key findings: Danish pre-registration radiography curricula contain little mention of projection radiography and a low proportion (n ¼ 17/144; 11.8%) of Danish radiography students chose to focus on projection radiography within publicly available BSc. theses between 2016 and 2020 as compared to topics
related to CT and MRI (n ¼ 60/144; 41.7%).
Conclusion: By changing how we as the profession perceive the role and position of projection radiography, we can start to rebuild its lost prestige and demand a greater, more detailed and clinically relevant
educational offering from academic partners. For this to commence, the language and terminology we
use to describe ourselves and tasks undertaken must reflect the complexity of the profession.
Implications for practice: Regardless of imaging modality, every patient should be assured that a radiographer with expertise in acquiring images of diagnostic quality undertakes their examination.
Reclaiming the prestige of projection radiography may lead students and radiographers to recognize
projection radiography as a demanding specialist field for the benefit of the patients.

Radiographers' perceptions of first year diagnostic radiography students' performance following implementation of a simulation-based education modelWilkinson, Elaine, Cadogan, Edward 21 June 2023 (has links)
Yes / Simulation-based education (SBE) partially replaced the clinical placement learning for a cohort of first year students on a BSc (Hons) Diagnostic Radiography programme. This was in response to the pressures on hospital-based training caused by increasing student numbers and following increased capability and positive outcomes for student learning in delivering SBE as a result of the COVID-19 pandemic.
A survey was distributed to diagnostic radiographers, across five NHS Trusts, involved in the clinical education of first year diagnostic radiography students at one UK university. The survey sought radiographers' perception of student performance in undertaking radiographic examinations, safety procedures, knowledge of anatomy, professionalism, and the impact of embedding simulation-based education through multichoice and free text questions. Descriptive and thematic analysis of the survey data was undertaken.
Twelve survey responses from radiographers across four Trusts were collated. Responses indicated the majority of radiographers perceived students to require the expected level of assistance in undertaking appendicular examinations, applying infection control and radiation safety measures, and had the expected level of radiographic anatomy knowledge. Students also interacted appropriately with service users, demonstrated increased confidence in coming into the clinical environment and were receptive to feedback. Some variation was noted, particularly in professionalism and engagement, though not always attributed to SBE.
Replacement of clinical placement with SBE was perceived to have provided appropriate learning opportunities and some additional benefits, however it was felt by some radiographers that SBE could not replace the experience of the real imaging environment.
Embedding simulated-based education requires a holistic approach and close collaboration with placement partners to ensure complimentary learning experiences in the clinical placement setting, and support achievement of the learning outcomes.

The impact of cervical spine radiographs in the diagnosis and management of patients that presented with neck pain to the Chiropractic Day Clinic at the Durban University of TechnologyEloff, Louis Stephanus January 2016 (has links)
Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Department of Chiropractic, Durban University of Technology, Durban, South Africa, 2016. / Background
Literature has shown that clinical and radiological diagnoses do not always correlate in patients with neck pain (Ferrari and Russel, 2003; Peterson and Hsu, 2004). It is not known if this applies to the Chiropractic Day Clinic (CDC) at the Durban University of Technology (DUT) and if the radiological diagnosis leads to a change in the patient’s initial management plan. The impact of cervical spine plain film radiographs will therefore be investigated in the diagnosis and management of patients that presented with neck pain to the CDC at the DUT. It is also not known whether the reason for referral for cervical spine plain film radiographs is always indicated as per the indications in the clinic handbook and radiological referral guidelines.
Objectives
Objectives were: (1) To determine the suspected pre-radiographic clinical diagnosis and management of the selected clinical records prior to referral for cervical spine plain film radiography; (2) To record the reasoning to send for cervical spine plain film radiographic imaging and to establish whether these are in line with proposed guidelines for referral as found in the literature; (3) To determine the relationship between the suspected pre-radiographic clinical and the radiological diagnoses of patients with neck pain; (4) To determine the number of incidental findings in the selected patients’ plain film radiographs; (5) To determine any change in the pre-radiographic clinical diagnoses and management following radiological reporting of the selected patient’s plain film radiographs.
Method
This was a quantitative, retrospective, clinical study. The archives at the CDC at the DUT were searched for cervical spine plain film radiographs between 1 January 1997 to 31 December 2013 and these were matched with the corresponding clinical records. After applying the inclusion and exclusion criteria, 73 records were included in the study. The patient’s personal information was coded to ensure confidentiality (Appendix A) and specific clinical and radiological information was recorded (Appendix B). Statistical analysis included the use of frequency counts, percentages, mean, standard deviation and range for the descriptive objectives.
Results
A total of 73 clinical files and corresponding plain film radiographs were assessed. The mean age of the patients was 44 years. The gender distribution was 64.4% (n=47) females and 35.6% (n=26) males. The most frequent primary radiological diagnosis was loss of lordosis at 41.1% (n=30) followed by cervical spondylosis at 35.6% (n=26) and old cervical spinal trauma at 12.3% (n=9). Sixty four percent (n=47) of patients in this study were sent for cervical spine plain film radiographs after their initial clinical consultation. Reasons that are not considered relevant indications for plain film radiographic referral were present in 46.2% (n=34) of cases; these described non-specific mechanical disorders. The most common reason for plain film radiographic referral was due to positive orthopaedic tests 57.5% (n=42). A total of 27.4% (n=20) of clinical files reviewed had a change in their initial clinical diagnosis and 72.6% (n=53) of these patients had no change in diagnosis. All of the post-radiographic clinical diagnoses were non-specific mechanical conditions. Numerous treatment modalities were utilized by the students with the most common pre-radiographic treatment being soft tissue therapy at 63.0% (n=46). A total of 75% (n=55) of patients had a change of treatment after plain film radiographs were performed and spinal manipulative therapy (SMT) was the main treatment added in 41% of cases.
Conclusion
Cervical spine plain film radiographs have little impact on the diagnosis of patients with non-specific mechanical neck pain without red flags. It was however found that plain film radiographs had an impact on the management in the majority of cases, especially with an increase in SMT use after plain film radiographs. / M

An evaluation of computerised tomography (CT) based treatment planning versus digitised image planning (standard planning technique) for carcinoma of the breast, using the four field breast techniqueGovender, Yoguvathie January 2007 (has links)
Submitted in fulfillment of Masters in Radiography, Durban University of Technology, Durban, 2007. / Aim/research questions
The aim of the study was to evaluate CT-based treatment planning versus
digitised image planning (standard planning technique) for carcinoma of the
breast, using the four-field breast technique, in terms of the depth of
supraclavicular and axillary nodes, the variability of the breast tissue and the
dose inhomogeneity at the matchline.
The variability of the depth of supraclavicular and axillary nodes has not been
documented in any local or national studies. When simulating patients for
treatment, it is evident that the anatomical variability of patient chest wall
thickness, shape and size is a contributing factor towards the final treatment
plan and dose distribution achieved. Therefore knowing the correct depth of
the nodes and being able to clearly demarcate the breast tissue should result
in a favourable dose administration.
The following questions were addressed:
What is the dose to the supraclavicular nodes from both plans?
What is the dose to the axillary nodes from both plans?
How do the plans differ in terms of dose coverage to the
supraclavicular and axillary nodes?
What is the relationship between the depth of the supraclavicular
nodes and the patient separation?
ii
What is the relationship between the depth of the axillary nodes and
the patient separation?
Does the target volume receive adequate dose coverage from the
plans?
How is dose to the heart volume affected by target coverage on
both plans?
How is dose to the lung volume affected by target coverage on both
plans?
What is the dose variability along the matchline?
Are the plans over dosing?
Are the plans under dosing? / M
