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.

Experts developing AI model that learns from calcium-scoring CT scans

The team hopes to develop a model that will estimate a patient's risk of major cardiovascular events and predict when such events are most likely to occur.

New cardiac prevention paradigm explored in TRANSFORM trial using AI and CCTA

Deepak Bhatt, MD, director of the Mount Sinai Fuster Heart Hospital and principal investigator of the TRANSFORM trial, explains an emerging technique for cardiac screening: combining coronary CT angiography with artificial intelligence for plaque analysis to create an approach similar to mammography.

Cardiologists to highlight the many benefits of AI-powered CCTA evaluations

Two renowned cardiologists are teaming up to explore the short- and long-term impact of using advanced AI platforms to evaluate coronary CCTA results for signs of coronary artery disease.

Key takeaways from RSNA 2024 for AI, CT, MRI and the radiology staffing shortage

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

SCCT leaders unpack the 2025 Medicare payment increase for coronary CTA

The Society of Cardiovascular Computed Tomography is cheering as a “huge win” the 2025 CMS payment increase for coronary CTA that more than doubles the current payment and “better aligns with the cost of providing CCTA services." The panel expects the move to bring an increase in CT utilization, more adoption with financial sustainability and greater access in currently underutilized areas.

‘A huge win’: CMS significantly increases Medicare payments for cardiac CT

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.

HeartLung Technologies, a Houston-based artificial intelligence (AI) company, has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for new software that assesses chest CT scans for signs of coronary artery disease (CAD) and other potentially fatal heart conditions. The newly cleared offering, AutoChamber, was designed with opportunistic heart evaluations in mind.
