Cardiac CT

A new study shows that even small plaque volume may be associated with significantly higher risk for cardiovascular events, making the enhanced spatial resolution available with advanced imaging even more critical in risk stratification.

Elevated coronary inflammation, measured with the CCTA-derived and AI-enabled perivascular fat attenuation index (FAI) score, was associated with over a 12-fold higher risk for cardiovascular mortality in patients with no diabetes, hypertension, smoking history or obesity, according to new research presented at the European Society of Cardiology (ESC) Congress.

New research presented at the European Society of Cardiology (ESC) conference demonstrates that fractional flow reserve (FFR) based off CCTA exams significantly decreases unnecessary invasive coronary angiography (ICA) procedures for patients with stable chest pain and obstructive stenosis.

In addition to providing stronger image quality, well-designed photon-counting CT systems may facilitate increased standardization, efficiency and simplification that may lead to reduced cognitive burden for radiologists.

The high-resolution temporal and spatial imaging with photon-counting CT bolster our understanding of the connections between anatomy and function in structural heart imaging.

Catch up on the latest blogs from Filippo Cademartiri, MD, PhD, who discusses topics ranging from CCTA scan acquisition and photon-counting CT to artificial intelligence and assessment of current plaque as a biomarker for evaluating MACE risk.

Smaller voxel size may offer insights into biology we could never access with conventional resolution.

New computed tomography (CT) research in July 2026 ranged from the ongoing impact of AI to significant declines in CT radiation dosing over the past decade to a growing recognition that coronary artery calcium (CAC) scoring alone may not be sufficient to convey a true picture of cardiovascular risk stratification.

In comparison to findings from a similar study in 2014, the national volume computed tomography (CT) dose index (CTDLvol) declined by 9.3 percent, according to newly published research involving 5 million CT exams for over 2.8 million adults in 2025.

Advanced imaging with photon-counting CT and AI detection of subtle calcification may lead to a reevaluation of the power of zero with coronary artery calcium (CAC) scoring.

The HOPPR EF Chest CT Narrative Model reportedly provides narrative language describing pertinent findings across pulmonary, upper abdominal, cardiac, mediastinal and soft tissue regions with processing of 3D chest CT volumes.

In the age of advanced CCTA imaging, a one-size-fits-all approach to image acquisition is a disservice to patients.

In a recent interview, Ron Blankstein, MD, discussed new research presented at the Society of Cardiovascular Computed Tomography (SCCT) conference, including a study examining the impact of notification of AI detection of coronary plaque on physicians prescribing lipid-lowering therapy.

In light of the recent death of Sen. Lindsey Graham from aortic dissection, we highlight pertinent diagnostic principles and key imaging findings for the timely detection of aortic dissection, a topic that Alan Braverman, MD, FACC, discussed in an interview with Diagnostic Imaging.

Out of multiple potential risk factors for the development of preeclampsia, ranging from hypertension to non-gestational diabetes and maternal age > 35, researchers found that pre-pregnancy coronary artery calcium (CAC) was the only risk factor significantly associated with preeclampsia.

For patients having CT angiography prior to TAVR procedures, researchers found that photon-counting detector CT (PCD-CT) offered higher specificity and PPV for detecting significant coronary artery disease (CAD), according to study findings to be presented at the Society of Cardiovascular Computed Tomography (SCCT) conference.

Photon-counting computed tomography (PCCT) is a foundational cornerstone that can facilitate detection, targeting and reversal of coronary artery disease.

Deep learning-based motion correction with the CLEAR Motion software reportedly bolsters cardiac imaging quality while the PIQE 1024 Deep Learning Reconstruction software offers equivalent SNR to photon-counting CT for high-resolution views of objects less than 0.5 mm.
