General Hints
• 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 wrists and elbow scans:
Patient lying in prone position, hands stretched
above the head and lying flat on a Bocollo pillow
(optional), ankles supported with a pad. Both wrists
should be examined together when necessary.
• Retrospective reconstruction can be done:
a)Use B50s kernel for soft tissue evaluation.
b)For targeted FoV images on the affected side, it is
advisable to enter the side being examined in the
comment line.
• In case of 3D study only, use kernel B10 and at least
50% overlapping image reconstruction.
• 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.
