Role of MR Elastography in Assessment of Liver Fibrosis

Abstract

Background: Liver fibrosis is a common consequence of various chronic liver diseases, including hepatitis, alcohol use disorder, and non-alcoholic fatty liver disease (NAFLD). The progressive nature of liver fibrosis can lead to cirrhosis, liver failure, and hepatocellular carcinoma. Early detection and accurate staging of liver fibrosis are crucial for determining prognosis and initiating appropriate treatment.

Aim: To assess the role of Magnetic Resonance Elastography (MRE) in the evaluation and staging of liver fibrosis, comparing it to traditional methods like liver biopsy and ultrasound-based techniques.

Methods: This study reviewed 150 patients diagnosed with chronic liver disease, who underwent MRE for liver fibrosis assessment. MRE was compared to histological liver biopsy results, considered the gold standard, to determine its sensitivity, specificity, and diagnostic accuracy.

Results: MRE demonstrated high diagnostic accuracy in detecting liver fibrosis, with a sensitivity of 90% and specificity of 85%. The technique was especially useful in assessing intermediate to advanced stages of fibrosis. It provided reliable, non-invasive results with a good correlation to biopsy findings.

Conclusion: MRE is a highly effective non-invasive imaging modality for the assessment of liver fibrosis. It offers an alternative to liver biopsy, particularly in cases where biopsy is contraindicated or difficult to obtain. Further studies and standardization of protocols are required for its widespread clinical application.
