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.

Emergency head CT use has more than doubled over last decade
A new analysis suggests approximately 1 out of every 10 patients presenting to the ED will complete a head CT during their visit.
Canon introduces new combined CT-angiography interventional system
Jaimin Chung, director of Canon Medical’s interventional X-ray and vascular business unit, explains the technology behind a new combined CT angiography interventional system aimed at neurology, trauma, stroke and pediatrics that recently received 510(k) FDA clearance.
FDA clears RapidAI's opportunistic aortic management tool
The solution can assess the aorta on any CT scan that offers visualization of it, including post-treatment and unenhanced noncontrast studies.
New data highlight 'systemic inconsistencies' in documentation of contrast reactions
Although uncommon and typically not life-threatening, hypersensitivity reactions have increased in recent decades alongside the significant rise in CT use.
CT colonography the most cost-effective cancer screening option for many
Findings from the Neiman Health Policy Institute and Northwell Health indicate that CTC is especially beneficial for underserved populations.

Professor Keith Channon, MD, MB ChB, FRCP, interventional cardiologist and the British Heart Foundation Professor Cardiovascular Medicine at the University of Oxford, and a co-founder of Caristo, explained an AHA 2023 study where AI identified coronary inflammation as a major silent risk factor and a strong predictor of heart attack risk.

AI model targets inflammation, helping cardiologists find 'invisible' heart patients

By focusing more on inflammation, cardiologists can ensure they are identifying patients who need help before it's too late.
