Shoulder
Hints in General
• Topogram: AP, 256 mm.
• Patient positioning:
Patient lying in supine position, the uninjured arm
placed above the head, the injured arm placed flat
against his body. If only one side is under investiga-
tion, position this side in the center and support the
other side with a Bocollo pillow (optional).
• If only one side is examined, it is advisable to enter
the side in the comment line on the routine card.
• 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.
Body kernels:
• As standard kernels for body tissue studies B30s or
B40s are recommended; softer images are obtained
with B20s or B10s (extremely soft). The kernels B31s
or B41s have about the same visual sharpness as B30s,
respectively, B40s, the image appearance, however,
is more agreeable due to a ”fine-grained” noise struc-
ture; quite often, the low contrast detectability is
improved by using B31s, B41s instead of B30s, B40s.
• The 2 kernels B35s and B46s are especially designed
for cardiac application, in particular, B35s should be
used for Ca-scoring, and B46s for patency of stents.
• For higher sharpness, as is required e. g. in patient
protocols for cervical spine, shoulder, extremities,
thorax, lung, the kernels B50s, B60s, B70s, B80s are
available.
• A special high resolution lung kernel is supplied
with B90s; by using kernel B90s, practically the same
image impression is obtained as with HCE-filtering of
a B40s image.
