Liver ultrasound

A liver ultrasound is an examination of the liver using ultrasound technology. Ultrasound is the preferred method for detecting various liver diseases and is also commonly used for routine physical examinations. There are currently two types of liver ultrasound examinations: B-mode ultrasound: This is a standard scan that allows doctors to observe changes in liver morphology. It is relatively inexpensive. However, it cannot thoroughly identify certain vascular lesions within the liver, in which case Doppler ultrasound can be used. Doppler ultrasound: This can be used for examining liver vascular lesions and hemodynamics. It is slightly more expensive and cannot differentiate between benign and malignant in a small number of liver space-occupying lesions, nor can it distinguish whether small intrahepatic nodules are inflammatory lesions or tumors. In such cases, a liver biopsy can be performed under ultrasound guidance. Ultrasound examination displays images of liver lesions, which are based on changes in acoustic physical properties. For the same lesion, the ultrasound image presentation varies at different stages of disease progression; conversely, different lesions with similar acoustic physical properties may have identical ultrasound image presentations. Therefore, ultrasound cannot provide a pathological anatomical diagnosis.
