Computed Tomography

Computed tomography (CT) is a fast and accurate imaging modality often used in emergency settings and trauma imaging. CT scans, with or without (or both) iodinated contrast are frequently used to image the brain, chest, abdomen and pelvis, but also have post-imaging reconstructive capabilities for detailed orthopedic imaging. It is now a standard imaging modality in emergency rooms to quickly assess patients. CT uses a series of X-ray images shot as the gantry rotates around the patient. Computer technology assembles these into into a dataset volume than can be slices on any access, or advanced visualization software can extract specific parts of the anatomy for study.

FDA clears new software for AI-powered CCTA assessments

Elucid's PlaqueIQ was trained to turn CCTA images into interactive 3D reports that help physicians visualize the presence of atherosclerosis.

Deep learning denoising produces quality trauma head CT images at 25% of the radiation dose

Denoising algorithm produces quality trauma head CTs at a fraction of the radiation dose

Radiation doses needed for quality head CT scans in trauma settings can be reduced by as much as 75% using DL-based denoising.

Guided errors in medical training improve interpretation skills post-residency

A new study in JAMA delves into how error management training builds adaptive expertise in interpreting head CT studies among nonradiologists. 

Time running out to comment on higher cardiac CT payments

Imaging experts have said the move could reshape the financial landscape for hospitals offering Cardiac CT services.
