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.

Two of the most read stories in November included CMS requiring all healthcare workers to get vaccinated by Jan. 4 and the FDA clearance of the first photon-counting CT system. The new CT technology is expected to be a paradigm shift in the future of CT technology over the next decade.

The FDA cleared the world's first photon-counting computed tomography (CT) scanner, the Siemens Naeotom Alpha, in late September. This new technology will likely change the future direction of CT. Biosense Webster also announced the first cases using its Heliostar radiofrequency balloon ablation catheter were completed in September. Both were among the top stories in October.

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:/
