IDEAL-IQ and MRS in quantitative assessment of liver fat content
Pages: 447-450
Year: Issue:  5
Journal: Radiologic Practice

Abstract: Obiective:To investigate the IDEAL-IQ and MRS in quantitative assessment of liver fat content.Methods:87 patients with non-alcoholic fatty liver disease and 20 healthy volunteers were scanned with MRS and then the fat content using IDEAL-IQ and MRS was calculated by postprocessing software.The thresholds of graded liver fat were achieved through analyzing the quantitative relationship between IDEAL-IQ and MRS.The difference and correlation between IDEAL-IQ and MRS were compared in quantitative assessment of liver fat content.Results:102 persons (102/107,95.8 %) were scanned by IDEAL-IQ successfully in 107 subjects.76 subjects (76/107,71.0 %) were scanned successfully with MRS scan.76 patients (71.0%,76/107) were scanned with MRS and IDEAL-IQ.The scores of relative lipid content (RLC) in MRS and fat fraction (FF) in IDEAL were 17.33± 10.86 and 16.28± 10.27,respectively.There was no significant difference between the RLC (MRS) and FF (IDEAL) (P=0.192).According the scattergram,there was a linear relationship between RLC and FF.Pearson correlation analysis showed that RLC and FF were positive.Conclusion:Fatty liver could be diagnosed accurately through MRS and IDEAL-IQ.
