超声检查甲状腺结节普通钙化及微钙化对甲状腺癌的诊断价值分析

目的：探讨超声检查甲状腺结节普通钙化及微钙化对甲状腺癌的诊断价值，以及不同钙化类型对癌变率的影响。方法回顾性分析125例甲状腺结节患者的超声诊断结果，并将其与病理检查结果进行比较。结果本次病理检查共显示癌变36例，占总例数的比例为28．8％。由超声检查出的钙化病例中，癌变率为88．9％，低于病理检查结果，差异有统计学意义（χ^2＝2．382，P＜0．05）。钙化组和非钙化组比较，钙化组癌变率显著高于非钙化组癌变率，差异有统计学意义（χ^2＝31．606，P＜0．01）。钙化组组内比较，微钙化癌变率显著高于普通钙化癌变率，差异有统计学意义（χ^2＝5．288，P＜0．05）。结论超声对于显示钙化病症具有较高的检出率，患者如果被检出钙化病症特别是微钙化病症，其癌变的风险会显著增加，要引起高度重视。

Analysis of the value of ultrasound detection of thyroid nodule calcification and micro calcification in diagnosis of thyroid carcinoma

Objective To investigate the diagnostic value of ultrasonography of thyroid nodule calcification and micro calcification of thyroid carcinoma ,and different types of canceration rate of calcification .Methods To retro-spectively analyse the results of ultrasonography of 125 cases of thyroid nodule patients and compare with pathological findings .Results The pathological examination showed 36 cases of canceration ,accounted for the proportion is 28 .8% .The ultrasonic inspection of calcified cases ,the incidence was 88 .9% ,lower than the results of pathological examination ,had significant difference （χ^2 =2 .382 ,P〈0 .05） .Comparison of calcification group and non calcification group ,calcification group canceration rate was significantly higher than that of non calcification group （χ^2 =31 .606 ,P〈0 .01） .In calcification groups ,micro calcification canceration rate was significantly higher than that of normal calcification（χ^2 =5 .288 ,P〈0 .05） .Conclusion Ultrasonography has a high detection rate of calcification ,if the patients are detected with calcification disorder especially microcalcification symptoms ,their risk of cancer will increase significantly ,should pay great attention to them .
