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.

New scanners and strategies for the ‘golden age of CCTA’

Sponsored by GE Healthcare

As coronary CT angiography (CCTA) continues its rapid expansion, scanner vendors are now offering more economical solutions to ensure access to imaging technology beyond premium systems most often only found at flagship hospitals and academic centers. To conquer CCTA’s technical challenges, new technologies and AI are being incorporated into a new scanner to simplify acquisition and consistently improve image quality.
