Ultrasound diagnosis of digestive system tumors

By | April 5, 2012

Ultrasound in Medicine is based on acoustic, medical and electronic engineering disciplines combined. Research and application of the physical characteristics of ultrasound, diagnostic ultrasound is called the science of human disease diagnostics.
Since the 1942 introduction of medical diagnostic ultrasound, along with the development of science and technology, ultrasound has also been rapid development, the overall trend is the development of dynamic images from the position to, from black and white to color image development, from two-dimensional image to three-dimensional image development, from reflection to transmission method to explore in order to get specific, the specificity of the ultrasonic signal, to quantitative, specific diagnostic purposes.
Because ultrasound is a noninvasive diagnostic tool, the human body without injury, safe and economic, has been in the field of medical diagnosis has been widely used. Tumors in the digestive system for liver, biliary tract, pancreatic cancer has a high diagnostic value, and the esophagus and gastrointestinal tumors, as can not penetrate gas and bone, to be limited diagnostic role. In recent years, the application of the probe body cavity to expand the scope of the diagnosis, such as the application of endoscopic ultrasound (This section specifically described in the digestive endoscopy).
In short, with the development of ultrasonic diagnostic equipment and diagnostic technology, interventional ultrasound have been developed, under the ultrasound needle aspiration cytology, ultrasound probe-guided needle aspiration biopsy cytology, histology, as The accurate diagnosis of clinical help
