When<unk>  is suspected, measurements are made of liver enzyme levels and other organ markers (creatinine, urea, electrolytes, LDH).<unk>  is most commonly diagnosed using ultrasound studies of the abdomen and retrograde angiography. Ultrasound may show obliteration of hepatic veins, thrombosis or stenosis, spiderweb vessels, large collateral vessels, or a hyperechoic cord replacing a normal vein. Computed tomography (CT) or magnetic resonance imaging (MRI) is sometimes employed although these methods are generally not as sensitive. Liver biopsy is nonspecific but sometimes necessary to differentiate between<unk>  and other causes of hepatomegaly and ascites, such as galactosemia or Reye's syndrome. Evaluation for a JAK2 V617F mutation is recommended.
