![Diagnosis of autosomal recessive polycystic kidney disease using MRI: MRI can be used to detect renal and extrarenal manifestations of autosomal recessive polycystic kidney disease (ARPKD). In this coronal, T2-weighted MRI scan of a 32-week-old fetus, the kidneys (arrow) are massively enlarged and are abnormally bright with innumerable tiny cysts, most of which cannot be individually resolved. Cystic biliary disease (arrowhead) and extremely low lung volumes (asterisk) in patients with ARPKD are due to oligohydramnios (deficiency of amniotic fluid).
