Liver Elastography and Doppler

Abstract

Shear-wave hepatic elastography is a worldwide technique, even with FDA approval at the end of 2015, and used for some time in Asian and European countries. It uses shear waves and in real time, the equipment has to have an ultra-fast system to capture the image of the same, around 5,000 frames / sec. In countries where it is widely used, it has reduced and replaced liver biopsy, thereby avoiding the side effects of the biopsy, bringing more safety and benefits to the patient. Initially it was indicated only for patients with Hepatitis C, later Hepatitis B and has now been used in other causes of diffuse liver diseases. Color Doppler, amplitude and spectral allows assessment of hepatic vascularization, facilitating the diagnosis of focal steatosis, nodular hyperplasia when identifying the nutrient artery, cardiac diseases, etc. It is an extremely useful supplement in the hepatic ultrasound study.
