Contrast-enhanced ultrasound in gallbladder disease: a pictorial review

Abstract

With its excellent contrast and spatial resolution, and the ability to image in real-time, ultrasound is the main imaging modality for assessing the gallbladder (GB). The application of contrast-enhanced ultrasound (CEUS) of the GB is now increasingly recognized as a useful addition to ultrasound and other cross-sectional imaging in the assessment of neoplastic and non-neoplastic GB disease. With the ability to image microcirculation and optimal contrast resolution, CEUS allows high-quality delineation in real-time, allowing for increased diagnostic confidence. In addition, ultrasound contrast agents have a favorable safety profile and can be used if CT or MR contrast agents are contraindica..
