Upper Extremities
Hints in General
•Topogram: TOP, 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 symmetrical 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, ankles supported with a pad. Both wrists should be examined together when necessary.
•Retrospective reconstruction can be done: a)Use B31s 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 B20s and at least 50% overlap in image reconstruction.
•To further optimize MPR image quality, we recom- mend that you reduce one or more of the following parameters: collimation, reconstruction increment, and slice width for image reconstruction.
