目的 :对 70例盆腔肿物患者进行 99m Tc-甲氧基异丁基异腈 ( MIBI)显像 ,以探讨其对卵巢恶性肿瘤的诊断价值。方法 :所有受检者于检查当日晨禁食。静脉注射 99m Tc- MIBI3 70～ 72 0 MBq后 ,分别于 5 ,15 ,3 0及 60分钟采集早、晚期下腹及盆腔前位图像各一帧。所有结果均有手术、活检或穿刺组织病理学检查做对照。结果 :2 0例卵巢恶性肿瘤中 17例有放射性填充 ( 85 % ) ,而 2 6例卵巢良性肿瘤中仅 3例有放射性填充 ( 11.5 % )。 4例腹腔内其他部位恶性肿瘤全部阳性 ,11例盆腔炎性包块仅 1例阳性 ,子宫肌瘤对照组中有 3例阳性。诊断灵敏度及特异性分别为 87.5 %及 84 .7%。结论 :99m Tc- MIBI盆腔显像对卵巢恶性肿瘤的术前诊断及盆腔肿瘤的鉴别诊断具有较高的灵敏度及特异性 ,有较好的临床使用价值
Objective: To investigate the diagnostic value of 99m Tc-methoxy-isobutyl isonitrile (MIBI) in 70 patients with pelvic masses for the diagnosis of ovarian cancer. Method: All subjects fasted on the morning of the examination. After intravenous injection of 99m Tc-MIBI3 70 ~ 72 0 MBq, the early and late lower abdomen and pelvic anterior images were collected at 5, 15, 30 and 60 minutes respectively. All results were surgery, biopsy or puncture histopathological examination as a control. RESULTS: Twenty-seven of 20 ovarian malignancies were radioactively filled (85%), whereas only 2 of the 26 benign ovarian tumors were radioactively filled (11.5%). 4 cases of other parts of the abdominal cavity of malignant tumors were all positive, 11 cases of pelvic inflammatory mass was only 1 case of positive, uterine fibroids control group, 3 cases were positive. The diagnostic sensitivity and specificity were 87.5% and 84.7%, respectively. Conclusions: 99m Tc-MIBI pelvic imaging has high sensitivity and specificity for the preoperative diagnosis of ovarian cancer and differential diagnosis of pelvic tumors, and has good clinical value
