Sample item

What does a bone scintigraphy study primarily detect?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Areas of altered osteoblastic activity

Bone scintigraphy detects altered skeletal tracer uptake reflecting osteoblastic activity and can identify multifocal metastases, stress injury, or infection patterns.

Option by option

  • A. Pulmonary artery filling defects

    Pulmonary emboli are assessed with vascular imaging.

  • B. Gallbladder stones directly

    Ultrasound is better for direct gallstone detection.

  • C. Exact cortical fracture lines in every case

    CT or radiography better defines cortical fracture anatomy.

  • D. Areas of altered osteoblastic activity (correct)

    Correct: uptake reflects regional bone turnover activity.
