甲状腺微小癌的超声影像及误漏诊原因探究

目的探讨甲状腺微小癌(thyroid micro carcinoma,TMC)的超声影像特征,防范误漏诊。方法选择我院收治的TMC 60例(观察组)和甲状腺良性病变60例(对照组)作为研究对象,观察组均行高频超声和CT检查,对照组仅行高频超声检查,评价高频超声在诊断TMC中的临床价值。结果观察组CT检查诊断符合率为76.67%,误诊率、漏诊率均为11.67%;高频超声诊断符合率为93.33%,误诊率为6.67%,漏诊率为0,两种方法在诊断符合率、误诊率、漏诊率方面比较差异均有统计学意义(P0.05)。观察组与对照组应用高频超声在诊断病灶数量、形态、边界、回声和钙化等方面比较差异均有统计学意义(P0.05)。结论高频超声诊断TMC有独到优势,其可从病灶数量、形态、边界、回声和钙化等方面加以鉴别,避免误诊误治。

Imaging Characteristics Analysis and Misdiagnosis Cause of Research of Ultrasound in the Treatment of Thyroid Mi-crocarcinoma

Objective To evaluate the imaging characteristics analysis and cause of misdiagnosis of ultrasound in the treatment of TMC. Methods 60 patients with TMC （ observation group） and 60 patients with benign and malignant thyroid lesions （ control group） were included in this study. Based on the sequence of enrollment and the patients were divided into two groups：experiential group （60 patients） receiving computed tomography and high-frequency ultrasound and control group （60 patients） receiving high-frequency ultrasound. The diagnosis function parameters were observed and compared. Results The rate of diagnostic accordance of CT scanning in observation group was 76. 67%;and misdiagnosis and missed diagnosis rates were 11. 67%. The accordance rate of the high-frequency ultrasound was 93. 33%;misdiagnosis rate and missed diagno-sis rate were 6. 67% and 0 with significant difference （P〈0. 05）. There was statistically significant difference between the le-sions numbers, morphology, boundary, echo and calcification in the diagnosis with high frequency ultrasound in the two groups （P〈0. 05）. Conclusion Ultrasound diagnosis has special effect in the treatment of TMC by evaluating the analysis of imaging characteristics and misdiagnosis cause.
