Computed Tomography

Cardiac computed tomography (CT) has become a primary cardiovascular imaging modality in the past 20 years, and was recommended as a 1A recommendation in the 2021 chest pain assessment guidelines. CT calcium scoring has became a primary risk assessment for coronary artery disease and whether patients should be on statins. Coronary CT angiography (CCTA) is used to for anatomical assessment of the arteries for plaque burden and to identify areas of blockage that may cause ischemia and heart attacks. Additional use of contrast CT perfusion or fractional flow reserve CT (FFR-CT) can offer physiological information on the function of the heart. CT plays a primary role in structural heart assessments for heart valves, repair of congenital defects and left atrial appendage occlusion (LAAO) for both pre-procedure planning and procedural guidance.

Researchers with University College London and the European Synchrotron Radiation Facility (ESRF) have used a new X-ray technique, hierarchical phase-contrast tomography (HiP-CT), to capture images of the human heart in unprecedented detail. The group shared its images, as well as a full analysis, in Radiology.[1]

New imaging technique captures human heart with 'unprecedented detail'

The new images were captured at the European Synchrotron Radiation Facility using hierarchical phase-contrast tomography. One specialist called them "Google Earth for the human heart."

"This was an unneeded burden, which was solely adding to the administrative hassles of medicine," said American Society of Nuclear Cardiology President Larry Phillips.

Avicenna.AI, a French artificial intelligence (AI) startup co-founded by a radiologist, has received U.S. Food and Drug Administration (FDA) clearance for two new offerings designed to automatically identify cardiovascular findings in CT scans, CINA-iPE and CINA-ASPECTS.

Radiology AI company gains FDA clearance for new CT offerings focused on PE, stroke

The newly approved AI models are designed to improve the detection of pulmonary embolisms and strokes in patients who undergo CT scans.

Breast arterial calcifications (BACs) identified on screening mammograms may help identify women who face a heightened risk of developing cardiovascular disease (CVD), according to a new analysis published in Clinical Imaging.

Incidental breast calcifications on mammograms linked to much higher risk of cardiovascular disease

These findings may say a lot more about a patient's long-term health than clinicians realized. 

Using computed tomography (CT) to perform coronary artery calcium (CAC) scoring can help identify symptomatic chest pain patients who do not require further testing, according to a new analysis published in Radiology.[1]

Coronary calcium scoring predicts when chest pain patients can skip invasive testing

Using CT to perform coronary artery calcium scoring on symptomatic chest pain patients can deliver significant value, according to a new data published in Radiology. 

Kate Hanneman, MD, University Of Toronto, explains why vendors and hospitals are increasingly discussing lowing their carbon footprint by starting with radiology. 

What does radiology have to do with climate change?

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."

Philips launches new AI-enabled CT scanner aimed at cardiology at ECR 2024

Philips introduced a new CT system at ECR aimed at the rapidly growing cardiac CT market, incorporating numerous AI features to optimize workflow and image quality.

Examples of the messages the Nanox AI algorithms display for incidental findings of spinal compression fractures and detection of coronary calcium. Both can help physicians better understand risk factors or need for therapy in patients through these types of opportunistic screenings on scans being performed for other reasons.

Routine chest CT often reveals patients at risk for cardiovascular disease, presenting radiology with ‘untapped’ potential

Rads only reported this incidental finding in about 31% to 44% of cases, experts detailed in the Journal of the American College of Radiology.
