【摘要】：目的通过微细血流成像(SMI)技术对甲状腺结节内血管分布形态的显示,并与CDFI和PD作比较,探讨SMI对诊断甲状腺癌的价值。方法回顾性分析经本院手术病理检查证实的228例甲状腺良、恶性结节患者共286个病灶的影像学资料,术前行CDFI、PD和SMI检查,比较良、恶性结节的血流分布形态及三种血流显像技术对甲状腺癌特征性血流的检出率,并分析其应用价值。结果 286个甲状腺结节病灶,包括105个良性结节和181个甲状腺癌。SMI图像显示,良性结节多呈环形血流,恶性结节以穿入型血流为主,差异有显著性(P0.01,特异度分别为97.2%和83.8%)。SMI对甲状腺癌穿入型血流的显示率81.8%(148/181),高于CDFI 53.6%(97/181)和PD 61.3%(111/181),差异均有显著性(P0.01);CDFI和PD对甲状腺癌穿入型血流的显示率无统计学差异(P0.05)。结论环形血流是良性结节的特异度表现,穿入型血流是甲状腺癌的特异度表现;SMI对穿入型血流的显示较CDFI和PD更敏感,对甲状腺癌的诊断有重要的价值。
[Abstract]:Objective to evaluate the value of SMI in the diagnosis of thyroid carcinoma by comparing it with CDFI and PD. Methods the imaging data of 286 lesions in 228 patients with benign and malignant thyroid nodules confirmed by surgical and pathological examination in our hospital were retrospectively analyzed. CDFIPD and SMI were performed before operation. The distribution of blood flow in malignant nodules and the detectable rate of characteristic blood flow in thyroid carcinoma by three kinds of blood flow imaging techniques were analyzed. Results 286 thyroid nodule lesions, including 105 benign nodules and 181 thyroid carcinomas, showed that most of the benign nodules showed annular blood flow, and the malignant nodules were mainly perforated blood flow. The specificity was 97.2% and 83.8%, respectively. There was no significant difference in the display rate of the penetrating blood flow in thyroid carcinoma between the two groups (81.8% and 83.8%, P < 0.05), which was higher than that of CDFI (53.6R / 97 / 181) and PD61.3T (111 / 181). There was no significant difference between P0.01T CDFI and PD in detecting the penetrating blood flow of thyroid carcinoma. Conclusion the annular blood flow is the specificity of benign nodules, and the penetrating blood flow is the specificity of thyroid carcinoma. SMI is more sensitive than CDFI and PD in the display of penetrating blood flow, and has important value in the diagnosis of thyroid carcinoma.
