Advances in application of four dimensional flow MRI in liver diseases
Liver blood flow is affected by its complex vascular anatomy, slow blood flow velocity, and human respiratory movement, which is difficult to evaluate liver blood flow by ultrasound, CT, and two dimensional phase contrast MRI (2D PC MRI). Four dimensional flow MRI (4D Flow MRI) can not only visualize the complex blood flow distribution of the liver, but also quantify hemodynamic abnormalities, which is an important imaging tool for evaluating liver hemodynamics. This article mainly introduces the technical principle of 4D Flow MRI and its current application in liver diseases, in order to provide a more comprehensive imaging basis for clinical understanding of the disease progression and efficacy evaluation of related diseases, and provide reference for future research direction.
