Abstract 【Objective】To investigate the influencing factors of acoustic radiation force impulse (ARFI) in detecting liver elasticity in patients with chronic hepatitis B (CHB). 【Methods】The clinical data of 80 patients with CHB admitted to our hospital from August 2014 to August 2018 were retrospectively analyzed. All patients received ARFI examination on the day of admission to determine the liver elasticity. Patients were divided into success group and failure group according to whether the detection was successful. The clinical characteristics of the two groups were compared, including gender, age, body mass index (BMI), degree of inflammation (G), liver fibrosis grade (S), steatosis grade (F), and detection position. The relationship between detection quality and clinical characteristics was analyzed. Logistic regression model was used to analyze the influencing factors of liver elasticity in patients with CHB detected by ARFI. 【Results】Of the 80 patients, 64 (80.00%) were successful and 16 (20.00%) failed. BMI < 24 kg /m2, steatosis grade F1 and supine position detection accounted for 65.63%, 95.31%, 53.13% and 59.38% respectively in the success group, which were higher than 37.50%, 31.25%, 0.00% and 25.00% in the failure group ( P <0.05). Logistic regression model suggested that BMI (≥ 24 kg /m2), steatosis grade (F2-F3) and body position (lateral position) were the influencing factors of liver elasticity in patients with CHB detected by ARFI ( P <0.05).【Conclusion】The detection of liver elasticity in patients with CHB by ARFI is affected by BMI, steatosis grade and body position, which should be paid attention to.
