UNLABELLED The aim of this study was to assess the value of 99mTc-hexakis2-methoxyisobutylisonitrile (MIBI) scintigraphy in patients with clinical and radiologic features of primary or metastatic musculoskeletal tumors. METHODS The scintigraphic findings for 84 patients were compared with the surgical and histologic findings. Each patient underwent three-phase bone scanning with 99mTc-methyle...

A 76-year-old man with bone metastases of prostate cancer diagnosed a year ago was admitted for relief of bone pain (visual analogue scale: 90%) most markedly in cervical spine and upper extremities due to skeletal metastases. His serum prostate specific antigen level was markedly increased (351 ng/ml). After documentation of sufficient tracer uptake in multiple bone metastases on whole-body 99...
