目的 探索此项检查诊断乳腺癌的临床应用价值及其与病理类型的关系.方法 60例女性乳腺肿块病人,静脉注射~(99m)TC-MIBI740～925MBq/入后5～10min静态显像.计算T/NT比值,检查后一周内手术.结果此方法诊断乳腺癌的灵敏度为80.4%,特异性为92.8%.其阳性率随组织病理学特点不同而差异明显.对癌细胞密度相对较低的乳腺癌显像时易造成假阴性.结论 ~(99m)TC-MIBI乳腺显像对鉴别乳腺良恶性病变,尤其在评价内乳淋巴结和腋窝淋巴结是否转移及术后残留复发方面具有良好的临床应用价值.
Objective To explore the clinical value of this test in the diagnosis of breast cancer and its relationship with the pathological type.Methods Sixty female breast masses were intravenously injected with ~ (99m) ~ (99m) TC-MIBI 740 ~ 925MBq / T / NT ratio.Results The sensitivity and specificity of this method in diagnosing breast cancer were 80.4% and 92.8%, respectively.The positive rate was significantly different with the histopathological features.For the patients with relatively low density of cancer cells Breast cancer can cause false negative when imaging.Conclusion ~ (99m) TC-MIBI breast imaging has good clinical value in differentiating benign and malignant breast lesions, especially in evaluating the metastasis of internal mammary lymph nodes and axillary lymph nodes and postoperative residual recurrence value.
