The diagnostic value of MR-imaging is tested on 130 patients with pathological retroperitoneal processes. Improved imaging techniques resulted in a more accurate delineation of tumor extension than seen with CT-imaging. Using a ratio of signal intensity from the adrenal tumors and the liver on T2-weighted images, it is usually possible to differentiate adenomas from metastases, carcinomas or phaeochromocytomas. New indications for renal MR-imaging would be parenchymal renal disease and transplant rejections. Moreover, MR allows visualization of lumbar lymph node-chains in the coronal view corresponding to the situs during surgery, thus, facilitating preoperative orientation for the surgeon.
对130例患有病理性腹膜后病变的患者进行了磁共振成像（MR-imaging）的诊断价值测试。改进后的成像技术比CT成像能更准确地描绘肿瘤的范围。利用T2加权图像上肾上腺肿瘤与肝脏的信号强度比，通常可以区分腺瘤与转移瘤、癌或嗜铬细胞瘤。肾脏MR成像的新适应证将是肾实质疾病和移植排斥反应。此外，MR能够在冠状面上显示与手术部位相对应的腰淋巴结链，从而便于外科医生进行术前定位。
