Overview

MRI findings of pyogenic liver abscess include hypointense and heterogenous centrally on T1, hyperintense signal on T2, enhancement of the capsule and multiple septations on T1+C, high signal within the abscess cavity on DWI, and low signal within the abscess on ACD.[1][2][3]

MRI

MRI findings of pyogenic liver abscess include:[1][2][3]

  • Hypointense centrally
  • Heterogenous
  • T2
  • Hyperintense signal
  • High signal intensity on T2 weighted images signifies perilesional edema
  • T1+C(Gd)
  • Enhancement of the capsule
  • Multiple septations
  • High signal within the abscess cavity
  • ACD
  • Low signal within the abscess cavity
