用９９ｍＴｃ－ＭＩＢＩ显像法对５６例经病理证实（３７例为恶性病变，１９例为良性病变）的甲状腺“冷”结节患者鉴别，结果血流丰富的共２２例（恶性病变中２０例、良性病变中２例）；９９ｍＴｃ－ＭＩＢＩ显像Ｔ／ＮＴ比值，恶性病变中乳头状癌、滤泡状癌、髓样癌、未分化癌均与９９ｍＴｃＯ－４显像有非常显著性差异（Ｐ＜０．００１），而良性病变中仅腺瘤有显著性差异（Ｐ＜０．０５），其余均无显著性差异（Ｐ＞０．０５）。９９ｍＴｃ－ＭＩＢＩ显像阳性率为７５．７％（２８／３７），诊断的准确率为７８．６％，特异性为８４．２％。该法对鉴别甲状腺“冷”结节有一定价值，可在临床上推广应用。
Forty-six patients with “nodular” thyroid nodules confirmed by pathology (malignant lesions of 37 and benign lesions of 19) were identified by 99mTc-MIBI imaging. Totally 22 patients (20 of malignant lesions , Benign lesions in 2 cases); 99mTc-MIBI imaging T / NT ratio, malignant lesions of papillary carcinoma, follicular carcinoma, medullary carcinoma, undifferentiated carcinoma with 99mTcO-4 imaging has a very significant difference ( P <0.001). There was no significant difference between benign and benign adenomas (P <0.05). There was no significant difference between the two groups (P> 0.05). The positive rate of 99mTc-MIBI imaging was 75.7% (28/37), the diagnostic accuracy was 78.6% and the specificity was 84.2%. The method of identification of thyroid “cold” nodules have some value, can be clinically applied.
