Hints in General
• Topogram: TOP, 512 mm for pelvis studies and
256 mm for studies of the hip and SI Joints.
• 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 are suspected. In some cases, air may
be substituted for a positive contrast agent. The use
of a vaginal tampon may be helpful in adult female
patients with suspected pelvis pathology.
• To further optimize MPR image quality we recom-
mend that you reduce one or more of the following:
collimation, reconstruction increment, and slice
width for image reconstruction.
• For pelvis studies, deselect CARE Dose for patients
> 120 kg.
Body Kernels
• As standard kernels for body tissue studies B31s or
B41s is recommended; softer images are obtained
with B20s.
