CT scanners are graded according to the number of slices of the body the rotating x-ray tube can image in one rotation. Many diagnostic imaging units use scanners with 16-64 slice capability; in contrast, European Scanning Centre’s Aquilion ONE images 320 slices with each rotation, enabling a faster and more detailed examination.
It is able to scan entire organs in a single rotation, avoiding step artefact or the need to ‘stitch’ images together, often leading to obscured images
It has the ability to scan patients with an abnormal heart rhythm, and the improved accuracy to image the ‘soft’ cholesterol-rich coronary artery plaque, which is the most likely to rupture and cause a heart attack.
It is capable of real time 4D imaging of moving joints including the bone, ligaments and tendons, which is often missed on static imaging. It is an important application for sport injuries.
It has the ability to image organ functions, including blood flow to the brain and heart. Its ability to perform high-quality cerebral and cardiac angiography is invaluable in the diagnosis of stenoses, malformations and aneurysms.
Virtual colonoscopies are able to reveal polyps as small as 4mm and can capture other abnormalities that are easily missed by the more conventional methods of viewing the bowel, such as invasive colonoscopy.
It is capable of imaging the entire chest in 3D, enabling even the smallest airways to be visualised with startling clarity. Lung nodules as small as 2mm can be detected.
