Multiple myeloma: MR patterns of response to treatment.

abstract：:To determine the impact of radiographic findings on the interpretation of bone and gallium scans of patients with active osteomyelitis, the authors reviewed the medical records and radiologic examinations of 104 patients. The only diagnostic finding of active disease on radiographs was the presence of a sequestrum (th...
