ASIS anterior superior iliac spine

aScan length varies depending upon patient size and component. An anterior–posterior topogram should be acquired to determine scan range. All areas should be scanned using a pitch of 1.0 and rotation time of 1.0 s and reconstructed using 1-mm slices and the kernel “BONE”. An extended scale should be used.
