Role of Magnetic Resonance Elastography in Assessment of Hepatic Focal Lesions

Abstract Background Hepatic focal lesions have been a common reason for consultation faced by gastroenterologists and hepatologists. It is important to consider not only malignant liver lesions, but also benign solid and cystic liver lesions. Objective to evaluate and confirm the role of magnetic resonant elastography in assessment of the hepatic focal lesions and differentiate benign from malignant hepatic focal lesions. Patients and Methods This is a cross sectional study included 30 patients with variety of focal lesions identified either by dynamic MRI or by histopathology. Results Our study showed that a cut off value of 4 Kpa had a 90% sensitivity, 85.7% specificity, 95% positive predictive value, 75% negative predictive value and accuracy 90 %. Conclusion MRE showed a great potential as a promising non invasive technique for quantitative evaluation of hepatic masses that could introduce more data useful in characterization of the focal lesions.
