The concept

The concept of this website is based on a previous site that was founded in 2008 and is still up and running. The website is composed as a book, where all sources are properly referenced, according to a good practice in scientific publications.

    Estimate of liver volume on CT or MRI - calculator

    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

    Parameter Value  
    Max. cranio-caudal dimension (CC)* cm
    Max. latero-lateral dimension (LL)* cm
    Max. antero-posterior dimension (AP)* cm

    * Required

    Volume:

    clear
