{ANSWER: C. Whichever configuration it did not pass (righty,
lefty, or both)}

13. If metallic objects are present in the non-operative leg, what
should be attempted?
A. Cancel the scan
B. Scan only the non-operative leg
, C. Isolate that leg from the scan region
D. Ignore it, since it does not affect the scan
{ANSWER: C. Isolate that leg from the scan region}
Segmentation
