Quantitative acoustic radiation force impulse imaging in evaluation on elasticity of liver in patients with chronic heart failure / 中国医学影像技术

ABSTRACT

Objective: To explore the value of quantitative acoustic radiation force impulse (ARFI) imaging in evaluation of liver elasticity in patients with chronic heart failure (HF). Methods: Totally 30 left HF patients (LHF group), 30 right HF patients (RHF group) and 30 healthy volunteers (control group) underwent routine ultrasound examination and biochemical examination, and then Young's modulus value of liver was detected using quantitative ARFI imaging. Correlations between Young's modulus value of liver and biochemical indexes, diameter of inferior vena cava, diameter of liver vein and oblique diameter of right lobe of liver were analyzed in patients with chronic HF. Results: Young's modulus value of liver in LHF group and RHF group were higher than that in control group (both P0.05). Conclusion: Quantitative ARFI imaging can be used to estimate the elasticity of liver in chronic HF patients. Liver elasticity is associated with the severity of heart failure.
