摘　　要：目的:探讨MSCT微血管半定量技术对甲状腺结节的诊断价值。方法:将159例经手术病理证实的甲状腺结节(共210个,且囊变区<50%)患者纳入研究,其中结节性甲状腺肿84例130个结节,甲状腺腺瘤51例54个结节,甲状腺癌24例26个结节。所有患者行低剂量MSCT平扫和增强扫描,使用Philips星云工作站后处理软件重建微血管可视化图像并计算结节内微血管比,对良恶性结节的微血管构成比进行统计学分析。结果:在VR和MIP微血管可视化图像上,良性结节内主要表现为微血管的数量少、形态规则,而在恶性结节内主要表现为微血管紊乱、粗细不均、形态不规则。良、恶性结节组的微血管构成比分别为0.3596±0.0905和0.5250±0.0778,两组间差异有统计学意义(t=3.126,P<0.01)。结论:MSCT微血管半定量分析技术对良恶性甲状腺结节的鉴别诊断有一定价值。Objective：To analyze the value of MSCT micro-vascular semi quantitative technique for diagnosing thyroid nodules. Methods： 159 patients with 210 thyroid nodules （cystic areas 〈50 % ） confirmed by postoperative pathology were included in this study. There were 130 nodules in 84 cases with nodular goiter goiter,54 thyroid adenomas in 51 cases,and 26 thyroid carcinomas in 24 cases. All the patients underwent plain and post-contrast MSCT scan using low-dose tech- niques, and the imaging data were postprocessed at Philips Xingyun workstation to obtain the visual microvessel images and constituent ratio of microvessels （CR） in the nodules. The CRs of the benign and malignant thyroid nodules were analyzed statistically. Results：On VR and MIP images, the microvessels in benign nodules showed sparse distribution and regular shape;and in malignant nodules they showed widespread,irregular shape and derangement distribution. The CRs of the be- nign and malignant thyroid nodules were 0. 3596 4-0. 0905 and 0. 5250 4-0. 0778 respectively with statistically significant difference （t=3. 126,P〈0.01）. Conclusion： MSCT micro-vascular semi-quantitative technique is helpful for the differential diagnosis of benign and malignant thyroid nodules.
