【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,P0.01)。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。
[Abstract]:Objective: to evaluate the diagnostic value of MSCT microvascular semi-quantitative technique in thyroid nodules.Methods: 159 cases of thyroid nodules (210 cases, 50 cystic areas) confirmed by operation and pathology were included in the study. Among them, 84 cases had nodular goiter, 51 cases had 54 nodules of thyroid adenoma and 24 cases had 26 nodules of thyroid carcinoma.All patients underwent low-dose MSCT plain scan and enhanced scanning. The microvessel visualization image was reconstructed by Philips Nebula workstation post-processing software and the intranodule microvessel ratio was calculated. The microvessel composition ratio of benign and malignant nodules was analyzed statistically.Results: in VR and MIP microvascular visualization images, the number of microvessels in benign nodules was small and the morphology was regular, while in malignant nodules, it was mainly characterized by microvascular disorder, uneven thickness and irregular morphology.The ratio of microvessel composition in benign and malignant nodule group was 0.3596 卤0.0905 and 0.5250 卤0.0778, respectively. The difference between the two groups was statistically significant (P 0.01).Conclusion the microvascular semi-quantitative analysis of MSCT is valuable in the differential diagnosis of benign and malignant thyroid nodules.
