作为临床三期研究的一部分为了决定使用超顺磁性口服造影剂(OMP)前后的MRI在检查卵巢癌术后患者腹部和盆部的诊断价值,作者对因卵巢癌而行经腹部子宫全切,双侧输卵管卵巢全切、网膜全切和盆腔淋巴结取样的23例患者(年龄39～79岁,平均53岁),完成了24次MR检查,MR表现均与第二次手术结果一致。口服的磁性微粒是以直径为3～4μm的单纯通过的聚合微粒作为载体,表面 As part of the clinical phase III study to determine the diagnostic value of MRI before and after the use of superparamagnetic OMP in the abdomen and pelvis of patients undergoing ovarian cancer surgery, the authors performed abdominal uterotomy for ovarian cancer. Twenty-three patients (aged 39-79 years, mean 53 years) who underwent total ovariectomy, total omentum, and pelvic lymph node sampling completed 24 MR examinations. MR findings were consistent with the results of the second operation. The orally-accepting magnetic microparticles are simply passed polymeric microparticles having a diameter of 3 to 4 μm as a carrier, and the surface
