title: [Diagnosis of kidney diseases with magnetic resonance tomography including the use of nuclear magnetic resonance contrast media].
abstract: Magnetic resonance imaging of normal and pathological kidneys and the method of examination are demonstrated. The anatomy of the kidneys is excellently displayed by means of magnetic resonance imaging which can also distinguish between the renal cortex and renal medulla. Renal tumors and cysts can easily be recognized and differentiated by means of magnetic resonance imaging and the extension of the tumor (staging) can be defined. The principles of magnetic resonance imaging contrast media are described as well as the primary results obtained from administration of contrast media in volunteers. At the present time, ultrasound and computed tomography are the first imaging methods in recognition and differentiation of space occupying lesions of the kidneys. Magnetic resonance imaging should only be utilised in complicated cases, e.g. haemorrhagic cysts or when computed tomographic results show a suspected tumor invasion of the renal vein or tumor thrombus in the vena cava.
