(one) coatingThe liver cancer of diametical <3cm is nodal often coating is complete. Coating is comprised by fibre, its acoustic resistance is fought relatively all round liver organization and cancer are swollen all tall, because this forms interfacial reflex, can show on graph of 2 dimension acoustic image circuit is fine thin low echo film surrounds whole cancer swollen section. The ply appraise of coating measures <0.5mm. The coating on acoustic image graph is smoother and even, configuration regulation, show a circle or elliptic. Reflect small liver cancer expansile growth characteristic. But the coating on acoustic image graph in tubercle two side show from beginning to end interrupt, this is the echo lose effect of big interface. When volume of cancer of the liver is very large, its coating is general punch-drunk. But the coating when also cancerous tubercle diameter is more than 5cm above is very complete still, right now, its inside echo accompanies dizzy show more.

(2) in-house echoDiscretion of echo of cancerous tubercle interior is differ, and have changeful tendency. Divide tubercle of even low echo beyond, other echo all belongs to all sorts of cancer tubercle inhomogenous distributing. The liver cancer of <1cm is nodal, supersonic detected check goes out rate for 33% one 37% . Cancerous tubercle classifies as follows by the discretion of echo: 1, low echo is nodal 2, tall echo is nodal 3, mixture sex is nodal 4, wait for echo tubercle 5, the concern that nodal echo discretion and blood offer

(3) the chromatic blood stream of cancerous tubercleTubercle of cancer of the liver and offer because of blood all round its rich, and the blood stream information that can obtain all sorts of concerning. The chromatic much general of acoustics radiography straps 2 harmonic supersonic detect the sensitivity that organizes blood stream is tall, the blood of liver cancer of can accurate report offers a condition. Color Duopule is supersonic the blood vessel drifting a person that can spot tubercle of cancer of the liver, pour out of the blood-vessel inside blood-vessel and tumour, blood-vessel drifting a person can be liver artery, also can be portal vein. Pour out of blood-vessel to be able to be liver vein, also can be portal vein. Expression of the blood-vessel inside tumour nods shape or chromatic inlaid for truncal shape, colour " bunch shape " spot piece, in spectrum much general is strapped liver artery, portal vein or liver vein blood stream can are in the analysis. The blood stream all round cancerous tubercle can be behaved to rectify circularity or arc around, duopule measures usable spectrum going out is blood stream of successional door arteries and veins or blood stream of beating sex artery.

(4) lymph node move1. Acoustic image of move of lymph node of area of gate of the first liver pursues at circle or kitchen range of elliptic low echo showing all round manager of cystic and cervical, bravery, portal vein 0.5 - 2cm size, individual or several. Many intumescent lymph node can bring about bravery manager press press, intercurrent and icteric. 2. The lymphatic converge that lymph node of area of gate of the 2nd liver transfers liver to rely on an end, horizontal stroke to separate a department comes 3 liver vein sheds venous finishing speech the person is in (door of the 2nd liver) all round lymph node. Here because the place is darker, constant not easy check gives intumescent lymph node. 3. Aorta of abdomen of move of the lymph node after peritonaeum and the lymph node all round pancreas is reached to transfer expression to be circle or kitchen of elliptic low echo all round vein finishing speech, individual or many.
