Hints in General
• Topogram: AP, 256 mm for joint studies.
• Patient positioning:
Depends on the region of examination.
In general, for bilateral studies, you should always
try to position the patient evenly whenever the
patient can comply.
• For knee scan:
Patient lying in supine position, feet first, promote
relaxation by placing Bocollo pillows between knees
and feet, bind feet together.
The only exceptions are extremely light patients. The
latter can remove the leg not being examined from
the gantry by bending it 90° at the hip and the knee
and placing the bottom of the same foot against the
gantry casing.
• For ankle and feet scan:
Patient lying in supine position, feet first.
Bind both ankles together if necessary to assure the
AP position of both feet.
Special positioning is not necessary since the real
time MPR could simulate any view of secondary
reconstruction.
