Employing an artificial intelligence (AI) tool to quantify airway-to-artery (AAR) diameter ratios on chest computed tomography (CT), researchers found the percentage of airways with an AAR greater than 1 was associated with increased pulmonary exacerbations in ever-smokers.

In a new study based on five- to six-year follow-up data from over 650,000 children and young adults who had at least one computed tomography (CT) exam prior to the age of 22, researchers found a “strong dose-response relationship” between increased CT radiation exposure and brain cancer.

Main pulmonary artery and right ventricular diameters on computed tomography (CT) scans of the thorax were predictors of pulmonary hypertension.

Ultra-low-dose computed tomography (ULDCT) may have similar efficacy as low-dose CT (LDCT) for detecting a variety of pulmonary conditions in people with current or past smoking histories, but had poor detection of ground glass opacification lesions, according to a recent prospective study presented at the Radiological Society of North America (RSNA) conference.

Enhancements for the BodyTom 64 Point-of-Care Mobile Computed Tomography (CT) Scanner include upgraded cross-sectional imaging capabilities and a Linux operating system.

Offering more than 70 clinical applications, the next-generation edition of the Advanced Visualization Workspace reportedly includes enhanced liver analysis and artificial intelligence (AI)-powered scoring of early brain infarction noted on computed tomography (CT) scans for patients with ischemic stroke.

New research suggests the Viz Aortic Dissection Algorithm has a 94.2 percent sensitivity rate for detecting aortic dissection on computed tomography (CT) angiography.

Emphasizing the benefits of annual lung cancer screening with low-dose computed tomography (CT), researchers noted high 20-year survival rates for a variety of early-stage lung cancer tumor presentations, including a 100 percent survival rate for those with non-solid or partly solid cancerous nodules.

GE Healthcare’s DaTscan is reportedly the first radiopharmaceutical tracer agent approved by the Food and Drug Administration (FDA) for use in patients with suspected dementia with Lewy bodies.

A new computed tomography study reveals that people who smoke marijuana may have a 70 percent higher risk of developing emphysema than non-smokers, and an age-matched subgroup analysis suggests marijuana use could be associated with a 26 percent higher risk of emphysema in comparison to tobacco-only smoking.

A new study of nearly 17 million emergency department (ED) visits by Medicare beneficiaries between 2005 and 2020 revealed the presence of non-physician practitioners (NPPs) was associated with a 5.3 percent increase in imaging.

In the newly released Lung-RADS 2022 classification system for computed tomography (CT) lung cancer screening, the American College of Radiology (ACR) has noted a variety of updates including new classification criteria for atypical pulmonary cysts and airway nodules, time intervals for nodule growth and a new stepped management approach for Lung-RADS categories 3 and 4A.

The recently launched Scenaria View Focus Edition computed tomography (CT) system features an advanced cardiac motion correction tool that reportedly provides significantly higher temporal resolution than conventional image reconstruction.

New research shows that 18F-NaF PET/CT had higher sensitivity, accuracy, and negative predictive value than 99mTc-MDP SPECT for bone metastases in patients deemed to be at high risk for prostate cancer or breast cancer.

In a multicenter study of 685 people who had positive findings for lung cancer on low-dose computed tomography (CT), researchers found that men, Black individuals, and smokers had lower rates of adherence with recommended follow-up care.

Reviewing data from over 4 million patients who presented to emergency departments with suspected urinary stone disease between 2012 and 2018, researchers noted a greater than 10 percent decrease in visits with no imaging study and a greater than 10 percent increase in visits with CT imaging.

Emphasizing ease of installation and a cloud-based service, Cleerly said its new Proxy software allows smooth transmission of coronary computed tomography angiography (CCTA) scans between interdisciplinary clinicians caring for patients with heart disease.

Emerging research revealed that a deep learning model had a nearly twofold increase in successful segmentation and reconstruction of coronary total occlusions (CTOs) on coronary computed tomography angiogram (CCTA) and a 73 percent reduction in post-processing and measurement time in comparison to a conventional manual approach.

Plaque Analysis and RoadMap Analysis, two artificial intelligence (AI)-enabled assessment products, may enhance clinical evaluation of coronary artery disease (CAD) on cardiac computed tomography angiography (CCTA).
