January 12th 2023In comparison to primary lung cancer, pulmonary metastases had a 33 percent higher frequency of ring-like peripheral high iodine concentration on dual-energy computed tomography (DECT), according to a new retrospective study.
Nine Takeaways from Recent Meta-Analysis on Lung Cancer Screening with Low-Dose CT
January 9th 2023From incidental findings and screening for chronic obstructive pulmonary disease (COPD) to surveillance imaging protocols and the advent of artificial intelligence (AI), the authors of a new meta-analysis examine insights and emerging trends from the last two decades of research on the use of low-dose computed tomography (CT) in lung cancer screening.
Study Shows Merits of Photon-Counting CT in Detecting Subtle Post-COVID Lung Abnormalities
December 22nd 2022In a recently published prospective study comparing photon-counting detector computed tomography (PCD CT) versus energy-integrating detector CT (EID CT) in patients with persistent symptoms after COVID-19 infection, researchers found that PCD CT discovered additional lung abnormalities in half of the study participants.
Study Says AI Can Enhance Chest CT Assessment of Bronchiectasis in Ever-Smokers
December 15th 2022Employing 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.

New Computed Tomography Study Shows High 20-Year Survival Rates for Early-Stage Lung Cancer
November 22nd 2022Emphasizing 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.
SPECT Imaging Agent Gets Expanded FDA Approval for Patients with Suspected Dementia with Lewy Bodies
November 16th 2022GE 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.
Chest CT Study Suggests Marijuana Smokers May Have Higher Emphysema Risk Than Tobacco-Only Smokers
November 15th 2022A 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.
Emergency Department Radiology: Study Shows Higher Imaging Orders by NPPs
November 11th 2022A 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.
Seven Takeaways from Lung-RADS 2022 for CT Lung Cancer Screening
November 10th 2022In 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.
New Computed Tomography System Offers Potential Benefits in Cardiac Imaging
November 9th 2022The 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.
Study Shows Less Than 50 Percent Adherence to Follow-Up After Positive CT Findings for Lung Cancer
November 4th 2022In 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.
