Question 4 Scan sites

Question 4: Scan sites

Which two anatomical sites are most commonly scanned for a central DXA bone density measurement?

Question 5 Spine positioning

Question 5: Spine positioning

During a posteroanterior lumbar spine DXA scan, how should the patient's legs be positioned to reduce the lumbar lordotic curve?

Question 6 Hip positioning

Question 6: Hip positioning

To properly position the proximal femur for a hip DXA scan, the technologist typically does what with the patient's leg?

Compared with a standard chest radiograph, the radiation dose from a typical central DXA scan is generally what?

Question 11 Artifacts

Question 11: Artifacts

A lumbar spine DXA scan shows a focal area of unusually high density over one vertebra caused by degenerative changes. How should this affect interpretation?

Question 18: Scan analysis

In a hip DXA analysis, the region of interest that includes the entire proximal femur measured by the system is called what?

Question 19 Follow up scans

Question 19: Follow up scans

When a patient returns for a follow up DXA scan to monitor therapy, why is it important to use the same densitometer and consistent positioning?

Question 20 Body composition
