The diagnosis of autosomal dominant polycystic kidney disease (ADPKD) can be diagnosed in a patient based on family history, age and the number of renal cysts seen on imaging studies.
The patient selected for imaging studies should be at risk based on a positive family history.
Imaging studies available:
(1) ultrasound (preferred screening method)
(2) CT scan
(3) MRI (may be the most sensitive method. This would be used for a patient from an affected family considering kidney donation to a family member.)
