Two formulas are calculated from R2* (star) value.

Wood et al.: LIC = 0.0254xR2+0,202
Garbowski:  LIC = 0.0290xR2^1.014

This formula can be used to estimate volume of the liver on crossectional imaging methods by measuring its maximum dimension in three perpendicular axes - caudocranial (CC), latero-lateral (LL), antero-posterior (AP). A normal value is considered <2000mL.

Volume = CC x LL x AP x 0.31

Budd-Chiari syndrome is a relatively rare disorder caused by occlusion of hepatic veins. It presents with abdominal pain, ascites, and hepatomegally.

Budd-Chiari syndrome has four clinical variants:

• acute
• subacute
• chronic
• fulminant

Budd-Chiari syndrome can be:

• primary (congenital obstruction  by webs or diaphragms)
• secondary (multiple causes)

Budd-Chiari syndrome has three morphological types:
