The study from Hyun Woo Goo demonstrated that CCT can be used to quantitatively evaluate RV remodeling after RV outflow tract reconstruction using a conduit in patients with pulmonary atresia and ventricular septal defect. Read more: doi.org/10.1016/j.jcct….

The study from Farooqi et al showed that CT-FFR values are lower in patients with anomalous right coronary artery (ARCA) from the left or noncoronary sinus and anatomic characteristics considered high-risk. 👉 ow.ly/wbmf50YuRxW.

This opinion paper from Han et al outlines essential components for technical, technologist and physician resources and programmatic support to develop and maintain a successful CCT in congenital heart disease program. doi.org/10.1016/j.jcct…

Submit your research for #SCCT2026! We're accepting standard and educational abstracts. The awards are supported by CVRF of So. Ca. - Ma Family @RonKarlsbergMD @DanielKarlsberg and @CanonMedicalUS. Deadline is TOMORROW March 6. Learn more: scct.org/page/ASMAbsSub…

Parikh et al found in adults >70 undergoing CCTA, PCD-CT was linked to ↓ ICA referrals, ↑ diagnostic accuracy & fewer indeterminate scans vs EID-CT—with similar overall accuracy. Potential to reduce unnecessary invasive procedures in older CAD patients doi.org/10.1016/j.jcct…

In this systematic review and meta-analysis, Kyriakoulis et al review the roles of CCTA and CACS in their preoperative cardiovascular risk of MACE stratification in patients undergoing noncardiac surgery. doi.org/10.1016/j.jcct…

Among adults undergoing cardiac imaging for #CoronaryArteryDisease, radiation dose varied widely and was higher for CCTA in low-income countries. The findings suggest a need for standardized protocols to reduce exposure. ja.ma/4cdJBno

In symptomatic patients without known coronary disease, #CCTA-derived plaque burden and volume independently predicted MACE beyond clinical risk and standard imaging findings. bit.ly/4aldMYF

SCCT is saddened to share the passing of Harvey Hecht, MD, FSCCT, founding member of the Society & 2015 Agatston Award recipient. Dr. Hecht was a pioneering force in cardiac imaging & advancing noninvasive coronary CT angiography. His work has helped save countless lives.

Welcome to the new year with our first image of the month! A rare cause of LVH, thanks to Dr Amir Manzelat, Dr Mathew Morgan and Dr Chris Critoph. Check it out 👉🏼 bsci.org.uk/image-of-the-m…

New meta-analysis by Bell et al demonstrate how quantified plaque volumes are associated with MACE in patients undergoing CCTA for stable CAD. Low attenuation plaque & total plaque volume were most robustly linked to risk. ow.ly/I9Kr50XlXsI

A survey of 2022 Medicare data by Yaman et al reveals that in 2022, over 240,000 cardiac CT (CCT) scans were billed to Medicare, but access isn’t equal: Some U.S. regions have <2 CCT readers per million beneficiaries. Women represent only 14% of readers. ow.ly/gaUe50XlXYk

Tremamunno et al show that ultra–high-resolution photon-counting CT (PCD-CT) detects more plaques but less stenosis than EID-CT, reclassifying >50% of patients to lower CAD-RADS. PCD-CT doesn’t just sharpen images—it changes interpretation. doi.org/10.1016/j.jcct…

CCT is evolving in the context of TAVR procedure. A review from Lorenzatti et al summarize role of CCT for patient selection, therapy optimization and long-term follow-up refinition. doi.org/10.1016/j.jcct….

A study from Fujito et al shows the role of AI-based Roadmap from HeartFlow in supporting accurate management of patients with coronary artery stenoses addressed to TAVR procedures. ow.ly/BM3750XA0PO

Zheng et al showed that the coronary geometry has clear phase-dependency, thus the phase dependency should not be ignored when CCT is used to quantify computational fluid dynamics-derived parameters. ow.ly/jvVr50XA1mU

Miller et al found that discrete non-calcified plaque on CCTA independently predicts future cardiovascular events in patients with CAC 0–100, underscoring the need for more comprehensive risk assessment. doi.org/10.1016/j.jcct…

Gray et al showed that CTCA is key for assessing paravalvular complications in prosthetic valve endocarditis — improving vegetation detection and surgical planning — and should be integrated with standard echocardiography. ow.ly/wHMi50XA1vr

Spontaneous coronary artery dissection (SCAD) predominantly affects middle-aged women. In this study by Pagonis et al, CCTA detected fewer than half of acute SCAD lesions seen on ICA, especially in distal vessels. ICA remains the diagnostic standard. ow.ly/KoWf50XJJ4R
