| [ Summary ] |
Recently, new modalities for ultrasound imaging, 3D/4D contrast-enhanced ultrasonography (CEUS) and Real-time Virtual Sonography (RVS) have been developed. 3D/4D-CEUS imaging can produce detailed information concerning localization, characterization of mass, and the relation ship between vessels/ducts and mass. This results in improved diagnoses. RVS can be used to observe an ultrasound images in real-time, by fusing the ultrasound images with a multiplanar reconstructed (MPR) CT images, using prescanned CT volume data. These techniques may be used to supplement diagnostic images which may provide unclear images. They can be employed to provide more detailed diagnostic imaging compared to conventional B-mode US and CTs. The resulting images may assistance in navigation therapy and improved diagnoses. These new techniques show promise in visualizing and diagnose biliary and pancreatic disease. |
