Fat Sparing of Surrounding Liver From Metastasis in Patients with Fatty Liver: MR Imaging with Histopathologic Correlation

Abstract

OBJECTIVE: The purpose of our study was to evaluate the characteristic MR imaging findings and histopathologic correlation of peritumoral fat sparing of liver metastasis in patients with fatty liver. CONCLUSION: Out-of-phase spoiled gradient-echo MR imaging was useful in detecting and characterizing the peritumoral fat sparing of liver metastasis in patients with fatty liver that was isointense to surrounding hepatic parenchyma on unenhanced in-phase spoiled gradient-echo, T2-weighted inversion recovery, and contrast-enhanced nonsuppressed spoiled gradient-echo MR imaging.
