The ultrasonic image of hepatocarcinoma displays _'s symptom
(1) Wrap up the membrane
Diameter lt; Hepatocarcinoma and tubercle of 3cm often charter the membrane intactly. It is made up of fibrous tissue to wrap up the membrane, its sound impedance liver tissue and cancer more around
It is swollen and high, so form interfaces to reflect, can reveal a detailed and thin low echo membrane surrounds the whole cancerous swelling festival in the two-dimentional audiovideo picture. Make thickness of membrane, estimate and examine lt; 0.5mm. Smoother and even when wrapping up the membrane on the audiovideo picture, shape rule, showing in round or ellipse. Reflect the characteristic of dilated growth of small hepatocarcinoma. But the intersection of bag and membrane at the the intersection of audiovideo and picture reveal, break down all the time in the intersection of tubercle and both sides, this lose the effect for big echo of interface. When hepatocarcinoma is very large in volume, smudgy its bag of membrane the same. Have cancer too tubercle diameter make membrane to be yet very much intact greater than 5cm above, at this moment, its many accompanying sound of inboard echo faints and behaves.
(2) Internal echo
The internal echo level of cancer and tubercle differs, and have changeable inclination. Except even low echo tubercle, various other cancer tubercle echoes do not belong to uniform distribution. lt; Hepatocarcinoma and tubercle of 1cm, the detection rate that the supersound measures is 33% one 37%. Cancer and tubercle, according to the height of the echo
It is classified as follows that it is low:
1,Low echo tubercle
2,High echo tubercle
3,Mixing tubercle
4,Wait for echo tubercle
5,Relation that the echo level of tubercle and blood support
(3) Colored blood flow of cancer and tubercle
Hepatocarcinoma tubercle and around because the blood supported abundantly, can win various relevant the intersection of blood flow and message. Colored Doppler's supersound of the harmonic acoustics radiography two times measures the sensitiveness of organizing blood flow high, can reflect accurately the blood of hepatocarcinoma supports the situation. Colored the intersection of Doppler and supersound can discern hepatocarcinoma tubercle flow the intersection of people and blood vessel, flow out blood vessel and blood vessel in the tumour, it can be the liver artery that people's blood vessel flows, it can also be the portal vein. It can be a liver vein to flow out the blood vessel, it can also be a portal vein. The blood vessel is shown as it was inlaid that the trunk, color are point-like or colored in tumour " Form a cluster " The intersection of spot and piece, can the intersection of liver and artery, portal vein or the intersection of liver and intravenous blood flow until spectral Doppler analyze. Cancer the intersection of tubercle and around blood flow can show as, enclose form or not arcual to round exactly, can it measures to be the intersection of continuity and the intersection of door and the intersection of pulse and blood flow or beating blood flow of artery with spectral Doppler.
