Estimate of spleen volume on CT or MRI, splenic index - calculator

This formula can be used to estimate volume of the spleen on crossectional imaging methods by measuring three dimensions - caudocranial (L), maximum size in axial plane (D), and maximum thickness in axial plane (T).

Splenic index = L x D x T
A normal value is considered ≤480.

Volume [mL] = 30 + 0.58 x L x D x T
A normal value is considered between 110 and 340mL

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
