Hypoechoic liver usually refers to cystic lesions, space-occupying lesions, etc. Hypoechoic liver usually refers to liver stones, calcified foci, etc., which need to be treated promptly once detected. Hypoechoic and hypoechoic in the liver are descriptors of ultrasound imaging, and can be differentiated into hypoechoic and hypoechoic because of the different intensity of reflections at the examination site. For example, stones, calcified foci and other high-density material in the ultrasound examination of the reflection intensity is stronger in the high echo; low echo reflection intensity is slightly lower than the normal echo of the liver, if the liver is low echo refers to cystic lesions or space-occupying lesions and so on. If the condition cannot be diagnosed by ultrasound examination of the liver, further CT enhancement scan or puncture biopsy is needed to make a clear diagnosis.
