CT scan

• CT scan is more sensitive than ultrasonography in detecting cysts of smaller size
• Because of cost effectiveness, it is not routinely used for diagnosing and detecting polycystic kidney disease
• However, it can be used for detecting cysts in children with the autosomal recessive type of polycystic kidney disease.

MRI

• It is more sensitive than CT scan and ultrasound, but not used routinely as it is an expensive diagnostic modality

MRA

• Magnetic resonance angiography (MRA) is used to detect intracranial aneurysms.
• It is not performed routinely, except in patients showing symptoms of an intracranial aneurysm or has a family history of one.

Autosomal dominant form

• Multiple, variably sized cortical and medullary based cysts
• Renomegaly
• Hemorrhagic cysts are often present
