Description

technical field [0001] The invention relates to a method and system for quantifying liver fat based on ultrasound. Background technique [0002] At present, fatty liver is a common diffuse liver disease. Early diagnosis and treatment of fatty liver can effectively prevent the progression of chronic liver disease and improve its prognosis. [0003] Clinically, doctors can use ultrasound images to make a qualitative diagnosis of fatty liver. This method has the advantages of high sensitivity, convenient operation, and low cost. Qualitative diagnostic methods. [0004] CT (Computed Tomography, computerized tomography) measurement of liver density can accurately detect liver fat deposition, and if supplemented with a corrected CT test tube, it can accurately quantify liver fat, but there is a risk of radiation exposure. [0005] Magnetic Resonance Imaging (MRI) and Magnetic Resonance Spectrum (MRS) can detect a small amount of fat deposits in liver cells, but like CT, they ar...
