Planes frequently used to identify radiologic and abdominal ultrasono‐graphic images such as transverse, coronal, and sagittal are generally not anatomically correct when applied to transvaginal ultrasonographic planes and images. More appropriate terminology specific for the planes imaged during transvaginal ultra‐sonography, such as TRANS‐pelvic and AP‐pelvic planes, are suggested. A TRANS‐pelvic plane refers to a plane imaged when the sound beam is directed across or from side to side in the pelvis. An AP‐pelvic plane refers to an image obtained when the sound beam is directed anteriorly and posteriorly.
