[Indications for magnetic resonance tomography of abdominal space-occupying lesions in children].

The frequency of magnetic resonance imaging for investigation of abdominal tumors in childhood is increasing. Malignancies of the liver can be visualized. For benign lesions the accuracy is high particularly in the case of hemangiomas. Magnetic resonance investigations are advisable in the presence of abdominal tumors, in order to differentiate lymph nodes and vascular involvement. Magnetic resonance imaging is mandatory in the case of retroperitoneal and presacral masses to depict any intraspinal tumor spread. RARE myelography can replace computed tomography myelography.
