[ Summary ] |
The newest ultrasound equipment can display a clear 3-dimensional image in a short time. In the liver, the usefulness of 3-dimensional ultrasonic diagnosis is that a pathological change is easy to assess and this information can be translated more objectively. With 3-dimensional displays, using B mode images, it is possible to stereographically observe the structure of intrahepatic vessels, the state of liver parenchyma and the liver surface, the shape of neoplasms, and the relative position between neoplasms and intrahepatic vessels. In 3-dimensional displays, using color or power Doppler methods and by combining these Doppler methods with B mode images, it is possible to assess peculiar intrahepatic hemodynamics, to depict tumor vessels, and to evaluate abnormalities in blood flow relevant to unusual echogenic regions. |
