BACKGROUND AND AIM
An accurate assessment of liver fibrosis is critical for the management of chronic hepatitis B (CHB) patients. Two-dimensional shear wave elastography (2D-SWE) and magnetic resonance elastography (MRE) have recently been proposed to diagnose liver fibrosis. To determine the optimal noninvasive method for diagnosing fibrosis in CHB, we conducted a meta-analysis to compare the performance of 2D-SWE and MRE for diagnosing fibrosis in patients with CHB.


METHODS
Literature databases were searched until January 1st 2021. Three measures, the summary area under the receiver operating characteristic curve (AUSROC), the summary diagnostic odds ratios, and the summary sensitivities and specificities, were used to assess the performance of 2D-SWE and MRE for detecting liver fibrosis.


RESULTS
Twenty-four studies with 5126 CHB patients were included. The summary sensitivities and specificities of 2D-SWE and MRE were 82% and 81%, 91% and 94%, respectively, for detecting significant fibrosis, 88% and 85%, 93% and 93%, respectively, for detecting advanced fibrosis, and 89% and 87%, 92% and 92%, respectively, for detecting cirrhosis. The AUSROC value of MRE (0.97) in predicting significant fibrosis was significantly higher than those of 2D-SWE (0.88, P < 0.001). The AUSROC values of 2D-SWE and MRE were 0.93 and 0.98, respectively, for the diagnosis of advanced fibrosis, and 0.94 and 0.97, respectively, for the diagnosis of cirrhosis.


CONCLUSIONS
MRE and 2D-SWE are excellent tools for staging fibrosis in patients with CHB. MRE probably exhibit the better diagnostic accuracy in detecting significant fibrosis as compared to 2D-SWE.
