Contrast-enhanced ultrasound – when and why?

Contrast-enhanced ultrasound (CEUS) has been utilised for a variety of applications, with published guidelines for its appropriate use. Several advantages of CEUS compared with other contrast-enhanced imaging techniques have been shown, including the absence of nephrotoxicity and ionising radiation, real-time assessment of vascularity and excellent spatial resolution. Ultrasound contrast agents (UCA) consist of microbubbles of […]

Adjusting contrast media dose to compensate for changes in kVp during portal phase liver CT – discussion

Appropriate contrast enhancement of organs in CT is key to promoting accurate diagnoses. With abdominal imaging it is particularly important to ensure the liver is appropriately enhanced as cancers may metastasise within it. As the vast majority of the hepatic blood supply comes from the portal vein, the portovenous (parenchymal) phase is often the most […]

Sonographer-led contrast-enhanced ultrasound services

It is widely understood that sonographer-led ultrasound services in the UK are well established and essential to meet demand. Indeed, sonographer role extension has been an underpinning part of the expansion of radiology services for over three decades and is widely supported by radiologists and referring clinicians alike. Undertaking contrast-enhanced ultrasound (CEUS) imaging requires a […]

Contrast-enhanced ultrasound: ready for prime time in paediatric imaging?

Ultrasound represents the first imaging step in the assessment of the paediatric patient. Ultrasound is well-tolerated by children, safe, with no contraindication, but above all involving no ionising radiation. With a suitable body habitus, ultrasound is well-suited in children to examine virtually any part of the body, with better imaging quality than in the adult, […]

Timing of portovenous (hepatic) phase abdominal CT

While abdominal CT can be performed at a range of differing intravenous contrast phases, rarely is the portal venous (hepatic) phase omitted. During a recent period at our DGH department, 38% of all patients referred for CT scanning received a portovenous phase abdominal scan, making it one of the most common scans performed.

The principles of trauma radiology

Individuals who have sustained major trauma require a well led, efficient and cohesive multidisciplinary team to best manage their injuries. Having early and accurate knowledge of the injuries sustained allows correct and prompt management. Radiology, specifically multidetector computed tomography (MDCT), is now fundamental in managing almost all major trauma patients; it has been shown to […]

The double bubble sign

The double bubble sign in neonates is seen on plain abdominal radiographs in a variety of conditions. It represents gas distended dilated stomach and proximal duodenum, and implies congenital proximal bowel obstruction. A newborn with a double bubble and no distal bowel gas can be presumed to have duodenal atresia and in most cases no […]

An introduction to contrast enhanced spectral mammography

Contrast enhanced spectral mammography (CESM) is a new technology, gaining acceptance throughout Europe and the USA, but only recently introduced to the UK. GE Healthcare is currently the only UK vendor of CESM, using the brand name Senobright. In this article, we will explore the theory behind the technology and the practicalities of performing the […]
