摘要
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.
PURPOSETo evaluate the value of 99mTc-MIBI imaging in the detection of breast tumors and to analyse the relationship between histopathologic features and imaging characteristics of breast cancer. METHODS Breast scintigraphies of 60 female patients with palpable breast masses were performed at 5-10 minutes after injection of 99mTc-MIBI 740-925 MBq/person, then the ratio value of T/NT were counted. All patients were operated in a week after scanning. RESULTS The sensitivity and the specificity of scintigraphy for breast cancers were 80. 4%, 92. 8% respectively. The histopathologic features of lesions greatly influenced their imaging characteristics. CONCLUSION 99mTc-MIBI breast scintigraphy is a valuable method for distinguishing malignance from benign breast masses. Potential roles of 99m Tc-MIBI are to evaluate axillary and intermammary lymphnodes and postlym-phoidectomy residual or recurrence of breast cancer.
