The blood flow signal status of hepatic hemangioma is different in different types of hemangioma, mainly including obvious blood flow signal, weak blood flow signal and no blood flow signal. 1. Obvious blood flow signal: the hemangioma is mainly dominated by arterial dilatation, and the blood flow rate is fast, so there will be obvious blood flow signal. 2. Weak blood flow signal: the vein itself is mainly dilated, and the corresponding blood flow speed is slow, the blood flow signal will be relatively weak. 3. No blood flow signal: the blood vessels within the lesion itself are relatively thin, in which the blood flow speed is very slow and cannot be measured by ultrasound probe, and it will be manifested as no blood flow signal. The blood flow signal of hepatic hemangioma will have a certain guiding effect on diagnosis, and if you want to make further judgment, you can check it through CT enhanced scan. Hepatic hemangioma increases significantly within a short period of time and causes abdominal pain, which requires timely medical observation and standardized treatment under the guidance of clinicians.
