Pilot study of non-contrast-enhanced MRI vs. ultrasound in renal transplant recipients with acquired cystic kidney disease: a prospective intra-individual comparison.

The incidence of renal cell carcinoma (RCC) after kidney transplantation is 15-fold increased. Acquired cystic kidney disease (ACKD) is one of the known risk factors. We performed a small pilot study to assess the role of non-enhanced magnetic resonance imaging (MRI) as a tool for intensified screening in renal transplant recipients with ACKD.
