Abstract
UNLABELLED: Contrast-enhanced ultrasound (CEUS) is a technique that has developed as an adjunct to conventional ultrasound. CEUS offers a number of benefits over conventional axial imaging with computerised tomography and magnetic resonance imaging, primarily as a "beside" test, without ionising radiation or the safety concerns associated with iodinated/gadolinium-based contrast agents. Intravascular use of ultrasound contrast agents (UCAs) is widespread with extensive evidence for effective use. Despite this, the potential utility of UCAs in physiological and non-physiological cavities has not been fully explored. The possibilities for endocavitary uses of CEUS are described in this review based on a single-centre experience including CEUS technique and utility in confirming drain placement, as well as within the biliary system, urinary system, gastrointestinal tract and intravascular catheters. TEACHING POINTS: • CEUS offers an excellent safety profile, spatial resolution and is radiation free. • Endocavitary CEUS provides real-time imaging similar to fluoroscopy in a portable setting. • Endocavitary CEUS can define internal architecture of physiological cavities. • Endocavitary CEUS can confirm drain position in physiological and non-physiological cavities.
