Computed Tomography (CT)

Cardiac computed tomography CT systems use a series of X-ray images to create an image volume dataset that can be sliced or manipulated on any plane using advanced visualization software. This channel includes content on CT scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (also called dual souce or dual energy CT), and interative image reconstruction software that can reduce dose and make lower-quality CT images diagnostic.

Test selection should be a shared decision between patient and physician rather than directed by insurers’ test substitution policies, according to a statement published online in the Journal of the American College of Cardiology.[1] The statement summarizes the proceedings of a recent summit convened by the American Society of Nuclear Cardiology (ASNC), leadership of the American College of Cardiology Imaging Council, American Society of Echocardiography (ASE), Society of Cardiovascular Computed Tomography

Images or a digital twin mitral valve of a patient created from cardiac ultrasound that were used to perform a virtual surgical procedure to test how the intervention would impact the patient prior to actually performing the procedure. The right image shows color coding for sheer stresses on the valve leaflets before and after the virtual surgery. The right image shows the model quantitation of leaflet coaptation at peak systole prior to the the virtual surgery. Read the original article in Plos One https:/

The inherent spectral capabilities of Mayo Clinic's new third-generation photon-counting CT research scanner allows clear visualization of the intact portions of the coronary artery lumen (arrowhead) by reducing the bright signal from the dense coronary calcifications (arrows). Spectral CT is able to bin photos on different energies that can be used to enhance or subtract chemical elements based on their spectral signature, such as calcium shown here, and iodine.
