^(99)Tc^m-MIBI阳性显像诊断甲状腺癌的临床价值

Clinical significance of ^(99)Tc^m-MIBI phil-tumor imaging in diagnosis of thyroid carcinoma

目的以临床病理学为基础,分析评价^(99)Tc^m-MIBI阳性显像诊断甲状腺癌的临床价值。方法对105例甲状腺癌患者行早期和延迟甲状腺阳性显像,并对其影像学特征进行分析比较。结果105例甲状腺癌中,^(99)Tc^m-MIBI阳性显像乳头状癌阳性有43例(82．7%),假阴性有9例(17．3%),灵敏度为82．7%;滤泡状癌阳性有37例(86．1%),假阴性有6例(14．0%),灵敏度为86．1%;其它类型阳性有5例(50．0%),假阴性有5例(50．0%),灵敏度为50．0%。其中乳头状癌组和滤泡状癌组灵敏度无明显差异(P＞0．05),但二者均高于其它类型组(P＜0．05)。结论^(99)Tc^m-MIBI阳性显像对甲状腺癌诊断具有重要的临床价值。

Objective To Analyze and evaluate the clinical significance of 99Tc^m-MIBI phil -tumor imaging in diagnosing thyroid carcinoma on the basis of clinical pathology. Methods Carrying out thyroid phil - tumor imaging of the nonage and delay were conducted and the imageology characteristics. Results Among one hundred and five cases with thyroid carcinoma,forty-three cases were positive at the papillary carcinoma with ^99Tc^m-MIBI phil -tumor imaging,and false negative were nine cases. The sensitivity was 82.7% ;thirty - seven cases were positive at the follicle carcinoma and six cases were false negative;the sensitivity was 86. 1 %. Five cases were positive at other carcinoma and false negative are five cases;the sensitivity was 50.0%. The follicle carcinoma and the papillary carcinoma didn＇ t have obvious diff, erence （P〉0. 05） ,but both were higher than the other groups（ P〈0. 05）. Conclusions It is of clinical significance to diagnose thyroid carcinoma by ^99Tc^m-MIBI phil - tumor imaging.
