title: The value of 67Ga scintigraphy in soft-tissue sarcoma and chondrosarcoma.
abstract: Forty-one 67Ga images were obtained for 33 patients with a diagnosis of soft-tissue sarcoma or chondrosarcoma. Tumor was detected in 27 cases of soft-tissue sarcoma; 25 (93%) of these were found on the Ga scans. The overall accuracy of scanning was 95.1%. All patients with positive scans had tumor present. In soft-tissue sarcoma patients the scan detected the tumor in 39 out of 45 sites. Ga scintigraphy was found to be useful in the initial evaluation and follow-up of these patients. If the Ga citrate scan is positive at multiple sites, the possibility of tumor being present is 100% with a false negative rate of 16%.
