Planning

Need of investigation

The diagnosis of cirrhosis can be made by physical examination and blood testing alone,[1] but ultrasonography is very helpful as an additional diagnostic tool at least in subtle disease.

Choice of investigation

Ultrasonography is the first-line modality of medical imaging in patients with suspected cirrhosis and/or portal hypertension.[2] US is also typically the initial, first-line modality choice for the diagnosis and follow-up of portal hypertension.[3]

Diagnosis

Irregular liver surface and ascites.

Cirrhosis is indicated by:

  • Surface nodularity: (sensitivity 88%, specificity 82-95%)[4]
  • General coarse and heterogeneous texture[4]
  • Segmental hypertrophy or atrophy[4]
  • Relative expansion of the caudate lobe, creating a ratio of caudate width compared to right lobe width of >0.65 (sensitivity 43-84%, specificity 100%)[4]
  • Reduction of the transverse diameter (<30 mm) of the medial segment of the left lobe (segment IV).[4]
  • Fatty change which is variable [4]
  • Signs of portal hypertension[4]
  • Dilated portal vein: >13 mm (sensitivity 42%, specificity 95-100%)[4]
  • Slow portal venous flow on Doppler: <15 cm/sec[4]
  • Reversal or alternating directions of portal venous flow[4]
  • Portal venous thrombosis with or without cavernous transformation[4]
  • Dilated superior mesenteric vein and splenic vein of > 10mm.[4] These should be measured during deep inspiration since it may vary with respiration.[4]
  • Loss of respiratory variation in superior mesenteric vein and splenic vein on spectral Doppler[4]
  • Re-canalisation and hepatofugal paraumbilical venous flow.[4]
  • Dilated porto-systemic collaterals.[4]
  • Portalisation of hepatic vein flow on Doppler[4]
  • Corkscrew appearance of hepatic arteries[4]
  • Increased velocity in hepatic artery[4]
  • Splenomegaly[4]
  • Ascites[4]

Surveillance

In patients with a diagnosis of cirrhosis, surveillance ultrasonography of hepatocellular cancer (HCC) is indicated, generally every 6 months.[5]
