Ultra-high-resolution spectral silicon-based photon-counting detector CT for coronary CT angiography: Initial results in a dynamic phantom
Recent improvements in CT detector technology have led to smaller detector pixels resolving frequencies beyond 20 lp/cm and enabled ultra-high-resolution CT. Silicon-based photon-counting detector (PCD) CT is one such technology that promises improved spatial and spectral resolution. However, when the detector pixel sizes are reduced, the impact of cardiac motion on CT images becomes more pronounced. we investigated the effects cardiac motion on the image quality of a clinical prototype Si-PCD scanner in a dynamic heart phantom at 60 bpm. We did not observe a significant difference in CT number accuracy and in-stent lumen ...

Predictors of non-calcified plaque presence and future adverse cardiovascular events in symptomatic rural Appalachian patients with a zero coronary artery calcium score
Coronary artery calcium (CAC) scoring is a proven predictor for future adverse cardiovascular events (CVE) in asymptomatic individuals. Data is emerging regarding the usefulness of non-calcified plaque (NCP) assessment on cardiac computed tomography (CCT) angiography in symptomatic patients with a zero CAC score for further risk assessment.

Coronary artery disease grading by cardiac CT for predicting outcome in patients with stable angina
The coronary atheroma burden drives major adverse cardiovascular events (MACE) in patients with suspected coronary heart disease (CHD). However, a consensus on how to grade disease burden for effective risk stratification is lacking. The purpose of this study was to compare the effectiveness of common CHD grading tools to risk stratify symptomatic patients. (Source: Journal of Cardiovascular Computed Tomography)

Technical Recommendations for Computed Tomography Guidance of Intervention in the Right Ventricular Outflow Tract: Native RVOT, Conduits and Bioprosthetic Valves
This consensus document for the performance of Cardiovascular Computed Tomography (CCT) to guide intervention in the right ventricular outflow tract (RVOT) in patients with congenital disease (CHD) was developed collaboratively by pediatric and adult interventionalists, surgeons and cardiac imagers with expertise specific to this patient subset. The document summarizes definitions of RVOT dysfunction as assessed by multi-modality imaging techniques and reviews existing consensus statements and guideline documents pertaining to indications for intervention.

When does anatomy triumph physiology?
Multivessel disease is a common finding on invasive coronary angiography in patients presenting with an acute coronary syndrome (ACS and STEMI)(1). Evidence suggests that physiology-guided revascularisation of non-culprit vessels improves clinical outcomes compared to treatment of the culprit's vessel only(2-6). This is predominantly driven by reduced urgent revascularisations and myocardial infarctions (MI). However, there remain concerns about the use of physiology in the acute setting. Additionally, we know that many lesions that may evolve into subsequent MI ’s are unstable plaques that may not be physiologically sig...

Accuracy of a virtual PCI planner based on coronary CT angiography in calcific lesions
Fractional Flow Reserve (FFR) measured after percutaneous coronary intervention (PCI) quantifies the degree of functional revascularization and is associated with improvement in angina and clinical outcomes.1,2 Post-PCI FFR can be accurately predicted by the FFRCT Planner, a novel tool allowing virtual stenting derived from FFRCT.3 The aim of this study was to assess the accuracy of the FFRCT Planner compared to invasive post-PCI FFR stratified by coronary calcification severity.

Prognostic Significance Of Automated Epicardial Adipose Tissue Quantification From Lung Cancer Screening CT
Introduction: Heavy smokers are at high cardiovascular (CV) risk. Routine lung cancer screening chest computed tomography (CT)-based quantification of epicardial adipose tissue (EAT) may help stratify CV risk beyond clinical risk factors and coronary artery calcium (CAC) score. We investigated the prognostic value of EAT volume and density measured automatically from low-dose non-ECG-gated non-contrast chest CT for lung cancer screening on all-cause and CV mortality.

Minimum Quantifiable Plaque Volume That Is Visually Detectable As Atherosclerosis Using Coronary Computed Tomography Angiography
Introduction: Artificial intelligence (AI)-based software has enabled automated detection and quantification of stenosis severity, plaque burden and plaque composition from coronary computed tomographic angiography (CCTA). Studies have shown that more coronary artery segments are identified as containing plaque using AI-based techniques compared to visual assessment. However, the minimum detectable plaque volume at which a coronary artery is considered abnormal by a human observer has not been defined. (Source: Journal of Cardiovascular Computed Tomography)

Prognostic Value Of A Novel Artificial Intelligence-based CCTA-derived Ischemia Algorithm In Patients With Suspected Coronary Artery Disease: Comparison Against Hybrid CCTA/PET Perfusion Imaging
Introduction: Coronary computed tomography angiography (CCTA) cannot directly assess myocardial ischemia in coronary artery disease (CAD). Therefore, guidelines recommend functional testing of suspected obstructive coronary stenosis. A novel artificial-intelligence (AI) -based algorithm, comprising a machine-learned method that leverages atherosclerosis and vascular morphology to determine ischemia from CCTA images, might be useful in this regard. The purpose of this study was to compare CCTA-derived AI-based ischemia algorithm against hybrid CCTA with selective positron emission tomography (PET) myocardial perfusion imagi...

Ultra-high-resolution Computed Tomography Reconstructed Using Deep Learning Reconstruction For The Assessment Of Coronary Arteries
Introduction: Computed Tomography Angiography (CCTA) is a robust, noninvasive imaging technique to assess coronary artery disease. However, conventional CT technology yields only modest accuracy of coronary artery stenosis assessment in calcified lesions due to spatial resolution limitations that result in blooming artifact. Recent developments in Ultra-High-Resolution Computed Tomography (UHRCT) and Deep Learning Reconstruction (DLR) offer the potential to overcome this limitation. Thus this goal of this study is to assess the image quality of the coronary arteries and calcified lesions for CCTA by UHRCT reconstructed usi...

The Impact Of Nitroglycerine Premedication On Dynamic Stress CT Perfusion Values And Their Correlation With Cardiac MR Imaging
Introduction: Computed Tomography Angiography (CTA) acquisition guidelines recommend the administration of nitroglycerin (NTG) prior to the examination to enhance coronary arteries evaluation. Dynamic stress CT perfusion (dynCTP) is a newer modality that allows quantitative evaluation of myocardial perfusion. A "rest-stress approach" involves performing dynCTP after CTA if abnormalities are detected, making it an attractive one-stop test. However, the cut-off values for myocardial blood flow (MBF) to identify significant hemodynamic lesions vary across studies, making it essential to identify the variables that affect it. ...

Radiomics Analysis Of Peri-coronary Adipose Tissue From Baseline Coronary Computed Tomography Angiography Enables Prediction Of Coronary Plaque Progression
Introduction: Plaque progression is an intermediate step between subclinical atherosclerosis and coronary events. Coronary computed tomography angiography (CCTA)-derived quantitative plaque features and peri-coronary adipose tissue (PCAT) have been confirmed as predictors for plaque progression. However, the relationship between plaque progression and PCAT radiomics has not been comprehensively evaluated. We analyzed radiomics features derived from PCAT on baseline CCTA to predict coronary plaque progression and evaluate their incremental value over quantitative plaque characteristics.
