全身骨骼放射性核素显像的定量分析

Quantitative analysis of wholebody bone radionuclide imaging

本文报道采用计算机程序对骨骼显像中骨病变进行定量分析。注射^(99m)Tc-MDP3h后进行全身骨骼放射性核素采集,求出显像图中放射性核素异常浓聚部位和对侧或邻近上下部位的放射性计数之比H。从60例癌症患者骨显像的154个异常浓聚部位统计,将H值分为1.5以下、1.5—2、2以上三个量级,对患者进行随访跟踪。结果表明采用定量分析诊断骨病变比目测方法更为有效。

This paper reported the study of quantitative analysis of bone imaging by computer in 60 cases with malignant tumor. The bor.e imaging were obtained 3 hours after the injection of 99mTc-MDP. The ratio of counts between the skeletal lesions and its contralateral or surrounding side was calculated, designated as H value. Three kinds of H value were found: <l.5,1.5 to 2,> The results showed that quantitative analysis of skeletal image is more effective than the visual inspection.
