The Pelvis

  • Janet E. Husband

Even with a detailed knowledge of anatomy, the pelvis is one of the most difficult regions to analyse with CT. Several factors contribute to the problems of interpretation. First, there is relatively little intervening fat between adjacent organs and structures. Secondly, small bowel loops have an inconstant shape and position and may be interpreted as representing a pelvic mass. Thirdly, many small structures pass through the pelvic adipose tissue (vessels and nerves) and these may cause confusion when attempting to identify minimal pelvic abnormalities such as parametrial extension of a cervical cancer or extravesical extension of a bladder tumour. In addition, and perhaps most importantly, in the female the long axes of the vagina, cervix and uterus lie in a longitudinal/oblique plane, so that the cross sectional display with CT is not the ideal format for demonstrating these organs.
