How to set‐up and perform contrast‐enhanced ultrasound

Abstract

Contrast‐enhanced ultrasound ( CEUS ) is an important part of current ultrasound imaging practice. Sonographers, radiologists and other sonologists should consider CEUS as a standard tool in the diagnostic toolbox of ultrasound and utilise it liberally to solve a wide range of imaging problems whilst reducing the need to resort to CT or MRI . Setting up a CEUS service is within easy reach of all motivated practitioners. The initial process requires assessment of the demand for CEUS , ensuring staff readiness, preparing administrative processes and obtaining CEUS supplies. The CEUS examination includes gaining informed consent, ensuring authorisation to administer contrast agent (preferably by means of a standing order), conventional pre‐scan of the area of interest, insertion of a peripheral IV cannula, preparation of the contrast agent, initiation of the contrast imaging mode, administration of the contrast agent, performance of the examination and aftercare. A number of other important considerations are discussed including cannulation and IV certification, scopes of practice for sonographers performing CEUS , contrast dosing, scheduling, training, interpretation, reporting and quality control.
