Pelvis
Hints in General
• Topogram: AP, 512 mm for pelvis studies and
256 mm for studies of the hip.
• Patient positioning:
Patient lying in supine position, arms positioned
comfortably above the head in the head-arm rest,
lower legs supported.
• A breathing command is not necessarily required
for the pelvic examination, since respiration does not
negatively influence this region.
• Rectal contrast medium administration:
Rectal contrast media is usually required to delineate
the rectum and sigmoid colon, if lower pelvic mass
or pathology is suspected. In some cases, air may be
substituted for a positive contrast agent. The use of
vaginal tampon may be helpful in adult female patients
with suspected pelvis pathology.
• To further optimize MPR image quality we recommend
that you reduce one or more of the following: colli-
mation, reconstruction increment, pitch factor while
using a wider slice width for image reconstruction.
