Abstract
Objective: To calculate the hepatic fat fraction using mDIXON MRI sequence and to then compare it to the fat fraction calculated using MR Spectroscopy which is considered to be the gold standard for estimation of hepatic fat amongst imaging techniques. The aim was to find if mDIXON fat fraction values
correlate with MR Spectroscopy fat fraction values.
Methods and Materials: 61 patients who were referred for MRI Liver to evaluate hepatic fat- fraction and who fulfilled the inclusion criteria were included in this study. All patients were subjected to MRI Liver scan on 3T MRI (Philips Ingenia) with fixed parameter specifications. Single reader assessed the images obtained using mDIXON and MR spectroscopy and post processing was done and fat fraction values were calculated using both the techniques.
Statistical Analysis: Used STATA software version 12(manufactured by Stata Corp LP, College Station, Texas).
Results & Conclusions: mDIXON fat fraction values showed a high degree of correlation with MR spectroscopy fat fraction values (correlation coefficient-0.975), signifying that mDIXON technique can be used in isolation to quantify hepatic steatosis.
