Technetium-99m (V) DMSA scintigraphy was performed in 17 patients with 37 chondrogenic tumors (13 osteochondromas, 14 enchondromas, and 10 chondrosarcomas) that had previously shown uptake of Tc-99m HMDP. Technetium-99m (V) DMSA showed high uptake by all chrondrosarcomas, but low or no uptake always indicated benign chondrogenic tumors. Technetium-99m (V) DMSA scintigraphy may be superior to Tc-99m HMDP scintigraphy for distinguishing benign and malignant chondrogenic tumors, and could also be useful for diagnosing the malignant transformation of chondrogenic tumors.
对17例患有37个软骨源性肿瘤（13个骨软骨瘤、14个内生软骨瘤和10个软骨肉瘤）的患者进行了锝-99m（V）二巯基丁二酸（DMSA）闪烁扫描，这些肿瘤先前已显示摄取锝-99m亚甲基二膦酸盐（HMDP）。锝-99m（V）DMSA显示所有软骨肉瘤均有高摄取，但低摄取或无摄取总是提示良性软骨源性肿瘤。锝-99m（V）DMSA闪烁扫描在区分良性和恶性软骨源性肿瘤方面可能优于锝-99m HMDP闪烁扫描，并且对诊断软骨源性肿瘤的恶变也可能有用。
