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%.

摘要

对33例诊断为软组织肉瘤或软骨肉瘤的患者进行了41次镓（67Ga）显像。在27例软组织肉瘤病例中检测到肿瘤；其中25例（93%）在镓扫描中被发现。扫描的总体准确率为95.1%。所有扫描呈阳性的患者均有肿瘤存在。在软组织肉瘤患者中，扫描在45个部位中的39个部位检测到了肿瘤。发现镓闪烁显像对这些患者的初始评估和随访有用。如果枸橼酸镓扫描在多个部位呈阳性，则肿瘤存在的可能性为100%，假阴性率为16%。
