Question

Which of the following are typical start and end locations for CT scans of the pelvis?

1) from the xyphoid process through the iliac crest
2) from the sternal notch through the iliac crest
3) from the iliac crest through the symphysis pubis
4) from the sternal notch through the symphysis pubis

Answer 1

CT scans of the pelvis typically start at the iliac crest and end at the symphysis pubis, capturing the true pelvis region that contains the bladder and other organs.

Step-by-step explanation:

The typical start and end locations for CT scans of the pelvis are most accurately represented by the third option: from the iliac crest through the symphysis pubis. The iliac crest is the superior margin of the ilium, part of the hip bone, and can be palpated along the waistline. The symphysis pubis is part of the pelvic girdle located anteriorly at the junction where the left and right pubic bones meet. These landmarks define the extent of the true pelvis or lesser pelvis which houses the bladder and other pelvic organs.
