Learning objectives
In this poster we focus on the application of Contrast-enhanced ultrasound (CEUS) in the evaluation of patients with gallbladder and bile duct disease,
emphasizing its advantages over conventional ultrasound and showing their correlation with other forms of image.
Technical considerations are discussed,
we describe the indications of the CEUS and illustrate the characteristics and limitations thereof in the evaluation of the biliary tract and the gallbladder.
In some cases we found very useful the quantification curves to compare the relative enhancement of the lesions compared...
Background
Introduction
Conventional ultrasound is the imaging modality of choice for evaluation of biliary pathology.
Has a high sensitivity in detecting gallbladder stones,
as well as in the assessment of dilatation of the bile duct,
both intra- and extrahepatic.
The major limitation is the small ability to detect vascularization and therefore to establish the nature of the tumors of the gallbladder and biliary tract.
In conventional ultrasound,
gallbladder tumors usually arise either as a solid mass occupying the whole of it or as a focal polypoid...
Findings and procedure details
Technique
Each patient must be fasting at least 8 hours before the exploration.
Before making the evaluation with CEUS of the gallbladder and the adjacent liver parenchyma,
they must be evaluated using grayscale conventional ultrasound and must have been detected the lesion involved.
We conducted our studies using ultrasound Toshiba Aplio 500 with a convex volumetric abdominal transducer (6.0 MHz).
Following intravenous bolus injection of 2.4 ml of contrast agent,
the images are acquired with the specific software to purchase them and photos and videos...
Conclusion
The CEUS allows a clear delineation of the disease of the bile duct and gallbladder and also,
compared to conventional ultrasound,
a safer diagnosis.
