Ultrasonography for accurate diagnosis: Gallbladder

Abstract

Abdominal ultrasonography is a noninvasive examination and is regarded as the first choice for gallbladder diseases. In order to obtain clear ultrasound images of the gallbladder, it is necessary to understand the its anatomy and surrounding organs to recognize artifacts, to adjust the ultrasound equipment to appropriate settings, and to know what to do if clear images are difficult to obtain. In order to make an accurate diagnosis, it is also necessary to be familiar with the ultrasonographic findings of typical gallbladder diseases. The key points in the diagnosis of gallbladder diseases will be discussed: abnormal morphology of the gallbladder, abnormal size, wall thickening, point hyperechogenicity and strong echogenicity, and elevated lesions or masses.
