Magnetnorezonantna dijagnostika akutnog pankreatitisa / Magnetoresonant diagnosis of pancreatitis acuta

Gvozdenović Katarina 25 October 2017 (has links)
<p>Akutni pankreatitis predstavlja zbirni pojam dinamičkih, lokalnih i sistemskih patofiziolo&scaron;kih procesa nastalih iznenadnim prodorom aktivnih litičkih pankreasnih enzima u žlezdani parenhim. Cilj istraživanja je da se Utvrditi senzitivnost difuzione sekvence magnetne rezonance (DWI) radi utvrđivanja morfolo&scaron;kih promena parenhima kod akutnog pankreatitisa. Poređenje difuzione mape i difuzionog koeficijenta kod pacijenata sa akutnim pankreatitisom i kod pacijenata sa morfolo&scaron;ki urednim parenhimom pankreasa na magnetnoj rezonanci. Utvrditi da li postoje statistički značajne razlike difuzionog koeficijenta kod pacijenata sa akutnim pankreatitisom u odnosu na pol. Utvrditi da li postoje statistički značajne razlike difuzionog koeficijenta kod pacijenata sa akutnim pankreatitisom u odnosu na godine. Odrediti prelomnu tačku difuzionog koeficijenta kod pacijenata sa akutnim pankreatitisom. Studija je bila prospektivnog karaktera i obuhvatilo je 30 ispitanika sa morfolo&scaron;ki urednim parenhimom pankreasa i 30 sa dijagnozom akutnog pankreatitisa unutar 72 sata od početka simptoma. Svi pacijenti su pregledani magnetnom rezonancom u Centru za radiologiju, Kliničkog Centra Vojvodine. Rezultati ukazuju da postoje razlike difuzionog koeficijenta kod pacijenata sa akutnim pankreatitisom i kontrolne grupe. Takođe smo dokazali da difuzioni koeficijent zavisi od pola i starosti i utvrdili smo prelomnu tačku difuzije za rano dijagnostikovanje akutnog pankreatitisa.</p> / <p>Acute pancreatitis is defined as cumulative term of dynamic local and general pathophysiological processes caused by sudden penetration of active lithic pancreatic enzymes in the glandular parenchyma. Goal of this research is to note the changes (sensitivity) in values of diffusion weighted images (DWI) in acute pancreatitis and to determine morphological changes in glandular parenchyma of pancreas. Comparation of DWI between patients with acute pancreatitis and patients with normal pancreatic parenchyma based on magnetic resonance (MRI). We also want to determine whether there were statistically significant differences of DWI in patients with acute pancreatitis in relation to sex and age. One of our goals also was to determine breakpoint of DWI as a sure sign of acute pancreatitis. This was prospective study and included 30 patients with morphologically healthy parenchyma of the pancreas (control group) and 30 with the diagnosis of acute pancreatitis &ndash; in first 72 hours of the onset of symptoms. All patients were examined on MRI in department of Radiology of Clinical Center of Vojvodina. Our results indicate that was a big difference of DWI between patients with acute pancreatitis and control group. We prove that DWI depends on the sex and age. 1,77x10-6mm/s2 was breakpoint which indicates acute pancreatitis.</p>
