Diffusion-weighted MRI for differentiating Wilms tumor from neuroblastoma. Occasionally, however, a neuroblastoma appears to be intrarenal. As well, a neuroblastoma is usually fixed, while a wilms tumor may be displaced. Metastatic disease is common and has a variety of patterns: Treatment depends on the patient's stage. Where MRI is available it is the investigation of choice for staging since it does not involve ionising radiation. Up to 30% may have evidence of calcification on the plain film.
