Abstract:
Objectives: To discuss the value of applying magnetic resonance diffusion-weighted imaging (DWI) to evaluate inflammatory activity from chronic viral hepatitis B.
Methods: One hundred forty-two patients with chronic viral hepatitis B who received treatment at The Fifth Medical Center of Chinese PLA General Hospital from January 2014 to December 2015 and 20 healthy persons in the control group who were scheduled to undergo nuclear magnetic resonance scanning and DWI examinations (b value = 0, 800 s/mm2), and the apparent diffusion coefficients (ADCs) were measured and compared with the biopsy results of hepatic tissue.
Results: The ADC value of the group with hepatitis B was lower than that of the healthy group (P<0.05), and the ADC value of the group with mild inflammation (G1) significantly differed from that of the group with moderate inflammation (G2) and that of the group with severe inflammation (G3-G4) (P<0.05).
Conclusions: Magnetic resonance diffusion-weighted imaging technology has high clinical value for evaluating the inflammatory activity from chronic hepatitis B, and the measured ADC value corresponds to the pathological grade well, so this method is worth clinical promotion and application
