[NMR imaging of the kidney].
NMR imaging was performed in 18 patients suffering from various renal disorders. 2 scanners were used, a 0.14T resistive prototype system and the superconducting Gyroscan S5. NMR imaging proved to be a very sensitive technique. Tumours as small as 5-10 mm were detected. Solid tumours and cysts could be distinguished. As a result of the excellent contrast resolution and tissue differentiation NMR imaging appears to be very accurate in the staging of renal cell carcinoma. Blood vessels within a tumour may be visible as little black dots. Because of their short T1 hemorrhagic cysts can be differentiated from simple cysts. Further prospective follow-up studies are required before a definite statement can be made as to the value of NMR imaging in diffuse parenchymal disease. Calcification were not detected. NMR imaging does not seem to be any more specific as to tissue characterisation than other imaging modalities.
