Answer

Bone scans can be beneficial when the use of MRI and CT scanning is contraindicated for evaluating osteomyelitis. However, although bone scans have high sensitivity for osteomyelitis, they have low specificity, resulting in an increased number of false-positive scans. Labeling with gallium and indium radionuclides may lead to more specificity for suspected osteomyelitis. [39]
