目的：探讨SPECT 全身骨显像与CT 扫描图像在 PACS系统联合观察对骨转移瘤诊断的增益价值。方法在PACS系统中，选择100例病理证实为恶性肿瘤且在1月内均行SPECT 全身骨显像及某个或多个部位的CT 扫描的患者。由2位资深影像学科医师共同分析SPECT全身骨显像、CT扫描图像及联合观察两种图像。对两种检查共同部位图像发现的病灶计数并行转移灶、非转移灶和不能确定的判断，根据术后病理或随访获得正确诊断。分别计算SPECT全身骨显像、CT扫描图像及联合观察两种图像对骨转移瘤显示的异常率、诊断的特异度和准确率。结果 SPECT 全身骨显像、CT扫描图像及联合观察两种图像对骨转移瘤显示的异常率分别为94.79、82.29、98.96％；诊断的特异度分别为45.10、96.08、99.02％；诊断的准确率分别为54.04、88.89、98.99％。结论 SPECT全身骨显像与CT扫描图像在 PACS系统联合观察可以提供更多的诊断信息，有明显的增益价值。

Objective To explore the added diagnostic value of SPECT imaging of whole body bone scan and CT scan images in PACS system in diagnosing bone metastases .Methods In the PACS system ,100 cases of patients with malignant tumors confirmed by pathology were selected ,whose one or more sites were examined by SPECT and CT scan in one month .SPECT images ,CT images and the combination of two kinds of image were analysed by 2 senior doctors of department of radiology .The numbers of lesion were counted respectively by two kinds of examination which include metastasis ,non metastasis and lesion de-termined difficultly .The correct diagnosis was obtained according to pathology or follow-up results .The abnormal rates of dis-play ,specificity and accuracy of SPECT images ,CT images and the combination of two kinds of images were calculated .Results The abnormal rates of display of SPECT images ,CT images and the combination of two kinds of image were 94.79、82.29、98.96% .The specificity rates of SPECT images ,CT images and the combination of two kinds of image were 45.10、96.08、99.02% .The accuracy rates of SPECT images ,CT images and the combination of two kinds of image were 54.04、88.89、98.99% .Conclusion The combined observation of SPECT images and CT images in PACS system provided more diagnostic in-formation and had the added diagnostic value obviously .
