Structural magnetic resonance imaging include lineal mesure, volume measure and volume rendered. They can detect the abnormal brain structure, especially the change of mesial temporal lobe in early onset of Alzheimer s disease. Recent studies more focused on functional imaging which can find the functional changes in brain. Prior to structural changes, functional changes happen, so it can reflect the sutile pathological process in Alzheimer s disease.

Seven cases with portal vein tumor thrombus were diagnosed by CO2-hepatic arterio-sonography (CO2-HAS). Their ultrasonographic features of CO2-HAS were as follows: several seconds after the injection of CO2 microbubble contrast, bright cloudy flowing echoes or several flowing echo stripes along the long axis of portal vein were seen in tumor thrombus. During interrupted phase of CO2 contrast injection there were still scattered unflowing bright echoes in tumor thrombus.
