[The clinical value of NMR tomography for retroperitoneal diagnosis].

NMR-tomography is a noninvasive diagnostic alternative to conventional imaging modalities. For clinical purpose there is no significant improvement in staging of kidney tumors and lymphnode metastases. The diagnostic value for complicated cysts and adrenal tumors is superior to all alternative imaging modalities as CT and sonography. Tumors of vena cava could be staged with an accuracy rate of 100%.
