Bone Densitometry Quiz

What does bone densitometry primarily measure?

• Bone flexibility

• Bone color

• Bone temperature

• Bone mineral density (BMD)

The condition characterized by low bone density and weaken of the bones that may lead to bone fracture is

• Scoliosis

• Osteoporosis

• Rheumatism

• Arthritis

What is the primary purpose of a DXA scan?

• To measure lung capacity

• To measure heart rate

• To measure blood pressure

• To measure bone mineral density

What does a T-score indicate?

• Deviation of BMD from a young adult population

• Deviation of BMD from an elderly population

• Deviation of BMD from a child population

• Deviation of BMD from a male population

The age group most affected by osteoporosis is

• Over 65 years

• 30 to 40 years

• Under 30 years

• 50 to 60 years

What does the Z-score compare?

• BMD to male population

• BMD to young adult population

• BMD to female population

• BMD to age-matched population

The primary component of a DXA scanner is

• Detector

• Transducer Probe

• Bore magnet

• Helical scanner

The purpose of the K-edge filter in DXA is

• To enhance image resolution

• To increase scanning speed

• To reduce radiation exposure

• To create dual energy x-ray beams

The typical exposure time for a DXA scan is

• 10 to 30 seconds

• 30 to 60 seconds

• 5 to 10 minutes

• 1 to 5 minutes

A benefit of using DXA for bone health assessment is

• Involves high radiation dose

• Long recovery time

• Noninvasive procedure

• Requires hospitalization
