The Digestive System Organ Scanning

Abstract

The objective of this chapter is how to learn to operate scanning of the digestive system organs and read the image figures, which contains the contents of the scanning method, section structures, measuring method as well as normal and clinical application value of the liver, gallbladder, bile ducts, pancreas, spleen, stomach, duodenum, jejunum, colon and rectum accompanied by 67 pictures of sonograms and 63 pictures of schematic diagrams. The patient’s position, preparation, the location and direction of the transducer are described in the scanning methods. Transverse, longitudinal, and oblique scanning methods are introduced. The section structures show every organ plane in the image figures. The measuring methods and normal describe the specification requirement of measurements in standard section and the normal range. One of the most characteristic in this atlas is the clinical application value which introduces the details of what diseases can be diagnosed by this section. The liver scanning includes the scans on the subxiphoid, right intercostal space, and right subcostal. The image figures, color Doppler flow images, and pulsed Doppler waveform of the portal vein, hepatic arteries, hepatic vein, and inferior vena cava are also provided.
