Question

bone scans can be used to diagnose causes of _______

multiple choice

kyphosis
osteoporosis
muscular weakness
blood disorders
bone infections

Explanation:

Analyze the diagnostic purpose of bone scans

Using the Bone Scans knowledge point

• A nuclear medicine bone scan detects areas of abnormal bone metabolism (increased or decreased bone turnover).
• It is highly sensitive for identifying active bone processes such as bone infections (osteomyelitis), fractures, and bone tumors.

Evaluate the given multiple-choice options

• kyphosis: This is a structural spinal curvature abnormality, typically diagnosed via standard X-rays rather than a nuclear bone scan.
• osteoporosis: This metabolic bone disease characterized by low bone density is diagnosed using a Dual-Energy X-ray Absorptiometry (DEXA) scan, not a nuclear bone scan.
• muscular weakness: This is a neuromuscular issue, evaluated using electromyography (EMG) or nerve conduction studies.
• blood disorders: These are typically diagnosed via blood tests (complete blood count) or bone marrow biopsies.
• bone infections: Active infections trigger an inflammatory response and increased bone remodeling, which shows up as a "hot spot" on a nuclear bone scan.

Answer:

• kyphosis
• osteoporosis
• muscular weakness
• blood disorders
• bone infections (Correct answer)
