Slight degree of liver fibrosis is usually difficult to be clarified by ordinary ultrasound examination, but the deeper degree of liver fibrosis can be roughly judged by ultrasound examination. Clinically, liver ultrasound is generally not used as the main item for checking liver fibrosis. Even though it is sometimes possible to determine the presence of liver fibrosis through ultrasound, it is not possible to further clarify the exact degree of liver fibrosis. People with such needs usually need to go to specialized hospitals for liver fibrosis screening through blood biochemistry tests, i.e. liver fibrosis 4, and liver fibrosis ultrasound. If liver fibrosis is suspected, it is recommended to seek prompt medical attention and under the guidance of a professional physician, liver fiber 4, liver puncture, liver function tests and other tests should be performed to clarify the condition, so as to obtain the best diagnosis and treatment.
