Diagnosis includes imaging with ultrasound, CT and/or MRI. The least expensive, non-invasive, and most reliable method is ultrasonography but smaller cysts may escape detection, while the resolution of CT and MRI will enable smaller cysts to be captured. However, the increased complexity and expense of CT and MRI is usually reserved for higher risk situations. MRI can be used to monitor the development of cysts and growth of<unk> s.Genetic test can be applicable to those who have a family history of PKD but is expensive and fails to detect PKD in 15% of cases where it is present. Antenatal scans Many forms of<unk>  can be detected in children prior to birth. Abnormalities which only affect one<unk>  are unlikely to cause a problem with the healthy arrival of a baby. Abnormalities which affect both<unk> s can have an effect on the baby's amniotic fluid volume which can in turn lead to problems with lung development. Some forms of obstruction can be very hard to differentiate from<unk>  renal disease on early scans.
