Eleven patients with transitional cell carcinoma of the bladder were examined with spin-echo MRI using a superconductive magnet operating at a field strength of 0.35 T. MRI results were compared with the CT findings in 10 of the patients. All subjects later underwent radical cystectomy including pelvic lymph-node dissection. MRI accuracy for staging was 64% using the TNM classification and 73% by the Jewett-Strong-Marshall system while CT accuracy was 40%. MRI provided improved demonstration of tumor invasion of perivesical fat planes, prostate, and seminal vesicles and greater anatomic detail was afforded by direct sagittal and coronal views.
11例膀胱移行细胞癌患者使用场强为0.35T的超导磁体进行自旋回波MRI检查。10例患者的MRI结果与CT检查结果进行了比较。所有受试者随后均接受了根治性膀胱切除术，包括盆腔淋巴结清扫术。使用TNM分类法时，MRI分期的准确率为64%，而按照Jewett-Strong-Marshall系统则为73%，而CT的准确率为40%。MRI能更好地显示肿瘤对膀胱周围脂肪平面、前列腺和精囊的侵犯，直接矢状面和冠状面视图能提供更详细的解剖细节。
