Question 2

When performing a cross-table lateral hip radiograph, the unaffected leg is elevated to:

Accepted Answer

Prevent superimposition of the soft tissue over the femoral neck

Answer

Elevating the unaffected leg removes it from the path of the horizontal beam, preventing superimposition over the proximal femur of interest.

Question 3

Which positioning landmark is used to locate the level of the iliac crest?

Accepted Answer

L4

Answer

The iliac crest is a palpable landmark that corresponds to the level of L4-L5 intervertebral space.

Question 4

A non-ambulatory patient requires a chest radiograph. If a PA erect projection cannot be obtained, the preferred alternative is:

Accepted Answer

AP erect

Answer

An AP erect projection is preferred over supine because it allows the diaphragm to descend and provides better visualization of lung fields and fluid levels.
