摘要
目的应用热断层扫描技术(Thermal Texture Maps,TTM)及彩超对甲状腺疾病进行评估与诊断,并比较两种检查方法的吻合度,旨在评价TTM对甲状腺疾病的评估应用价值。方法采用横断面研究,选取行TTM全身检测与甲状腺彩超检查者1344例,将TTM检测的阳性和阴性与彩超诊断的甲状腺异常和正常这四种数据进行诊断试验四格表运算,以取得各项评价指标;并将TTM评估与彩超诊断甲状腺疾病的情况进行κ系数检验。结果 TTM对甲状腺疾病的评估特异性较强(70.3%),准确度及敏感度分别为61.8%和52.4%;两种诊断方法的吻合系数为κ=0.229,P=0.000<0.05,说明两种诊断方法的吻合度较弱。结论 TTM作为一个体检项目对甲状腺疾病的早期筛查有一定的应用价值,但TTM作为一种新型的功能影像检查技术,尚需利用现有较成熟的影像技术来不断完善。
Abstract： Objective To assess and diagnose thyroid disease by using thermal texture maps and ultrasonography, and compare the goodness of fit for these two methods so that the assessed value of TTM on thyroid disease can be evaluated. Methods A cross-sectional study was conducted on 1344 cases who were detected by using TTM and color Doppler ultrasonography for thyroid disease. Positive and negative data obtained by TTM and abnormal and normal data obtained by color Doppler ultrasonography were analyzed by using diagnostic test fourfold table in order to get the evaluation indexes. Than using tc coefficient test to compare diagnosis results of the two methods. Results The assessment specificity of TTM on thyroid disease was better（70.3%）, and its accuracy and sensitivity were 61.8% and 52.4%, respectively. The goodness of fit of the two diagnostic methods was poor（to=0.229, P=-0.000〈0.05）. Conclusion As one of the medical projects, TTM has certain application value in early screening of thyroid disease. However, as one of new functional imaging technologies, TTM should be constantly improved by using mature image technologies.
