目的 :评价 99m锝标记的甲氧基异丁基异腈 (99m Tc- MIBI)腋窝显像在早期乳腺癌中的应用价值。方法 :随机选取 40例同侧腋窝无肿大淋巴结的住院乳腺癌患者 ,术前 3位 99m Tc- MIBI显像 ,计算病变与周围正常组织的放射性比值 ,以术后病理检查为金标准 ,判断该方法在诊断腋窝淋巴结转移的敏感性、特异性及准确性。结果 :99m Tc- MIBI腋窝显像敏感性 78.6 % (11/ 14) ,特异性为 84.6 % (2 2 / 2 6 ) ,准确性为 82 .5 % (33/ 40 )。结论 :99m Tc-MIBI腋窝显像有助于早期乳腺癌手术方案的选择
Objective: To evaluate the value of 99m technetium-labeled methoxyisobutylisonitrile (99m Tc-MIBI) axillary imaging in early breast cancer. Methods: Forty patients with ipsilateral axillary lymph nodes without lymph nodes were enrolled in the study. Three 99m Tc-MIBI images were collected before operation to calculate the radiological ratio of the lesions to normal tissues. The postoperative pathological examination was used as the gold standard to judge The method in the diagnosis of axillary lymph node metastasis of the sensitivity, specificity and accuracy. Results: The sensitivity of axillary imaging in 99m Tc-MIBI was 78.6% (11/14), the specificity was 84.6% (2 2/26) and the accuracy was 82.5% (33/40). Conclusions: 99m Tc-MIBI axillary imaging is helpful for the selection of surgical options for early breast cancer
