The use of magnetic resonance (MR) imaging for evaluating the abdomen and pelvis has been limited by the lack of a suitable contrast agent. The purpose of this study was to compare axial MR imaging after rectal barium administration with computed tomography (CT) for delineation of normal anatomy and lesions of the pelvis. MR images and CT scans of 11 patients were studied retrospectively and independently by four radiologists. No substantial differences in the visualization of normal bowel, iliac vessels, lymph nodes, bladder, prostate, seminal vesicles, uterus, and cervix and in detection of abnormalities were seen between CT scans and axial MR images obtained after barium administration. This preliminary study suggests that axial MR imaging with rectal barium is a useful alternative to CT in evaluating pelvic disease.
由于缺乏合适的造影剂，磁共振（MR）成像在评估腹部和盆腔方面的应用受到限制。本研究的目的是比较直肠注入钡剂后的轴向MR成像与计算机断层扫描（CT）在描绘盆腔正常解剖结构和病变方面的情况。11例患者的MR图像和CT扫描由4位放射科医生进行回顾性独立研究。在CT扫描与直肠注入钡剂后获得的轴向MR图像之间，在正常肠管、髂血管、淋巴结、膀胱、前列腺、精囊、子宫和宫颈的显示以及异常检测方面未发现实质性差异。这项初步研究表明，直肠注入钡剂后的轴向MR成像在评估盆腔疾病方面是CT的一种有用替代方法。
