Lower Extremities
• 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.
Body Kernels
The endings “s” or “f” depend on the rotation time.
• 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 structure; quite often, the low contrast detect-
ability is improved by using B31s, B41s instead of
B30s, B40s.
• For higher sharpness, as is required e.g. in patient
protocols for cervical spine, shoulder, extremities,
thorax, the kernels B50s, B60s, B70s, B80s are avail-
able.
