Liver ultrasound

Ultrasound detection technology is the first choice for various liver diseases. Two-dimensional real-time ultrasound imaging is mainly used for liver morphological changes, and two-color Doppler blood flow imaging is used for liver vascular disease and hemodynamic examination. Ultrasound examination showed a liver lesion image, which is a property change of acoustic physics. The same lesions have different appearances at different stages of the course of the disease; while different lesions have similar acoustic and physical properties, the performance of the ultrasound images may be the same. So ultrasound does not suggest a diagnosis of pathological anatomy. Ultrasound detection of a small number of liver occupying lesions cannot distinguish benign and malignant, such as diffuse cirrhosis and diffuse liver cancer. Some intrahepatic nodules are difficult to distinguish as inflammatory or tumor. Interventional liver biopsy or other tests can be performed under ultrasound localization if necessary.
