The Diagnostic Imaging CT modality focus page provides information, videos, podcasts, and the latest news about industry product developments, trial results, screening guidelines, and protocol guidance that touch on the use of CT across the healthcare continuum, from various cancer screenings, such as lung and colon, to cardiothoracic imaging, to appendicitis, and more.
June 7th 2023
The use of contrast-enhanced computed tomography (CECT) was associated with more than double the risk of contrast-induced acute kidney injury (CI-AKI) in patients with diabetes and an estimated glomerular filtration rate (eGFR) less than 30 mL/min/1.73 m2 in comparison to the use of non-contrast CT in this population.
Addressing the Radiological Taffy Pull: Suggestions for Communicating Worklist PrioritiesDecember 26th 2022
In order to alleviate some of the challenges with radiology worklist overload, this radiologist suggests alternative approaches for conveying new imaging requests and priorities.
Study Shows Merits of Photon-Counting CT in Detecting Subtle Post-COVID Lung AbnormalitiesDecember 22nd 2022
In 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-SmokersDecember 15th 2022
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.
Large Multinational Study Shows Link Between CT Radiation Exposure and Brain Cancer in Children and Young AdultsDecember 8th 2022
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.
Radiologic Parameters of Pulmonary Hypertension on Thorax CT May Help Risk Stratify Patients with Fibrosing Interstitial Lung DiseaseNovember 30th 2022
Main pulmonary artery and right ventricular diameters on computed tomography (CT) scans of the thorax were predictors of pulmonary hypertension.
Can Ultra-Low-Dose CT be Effective for Lung Cancer Screening in Current or Past Smokers?November 29th 2022
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.
Philips Launches AI-Enabled 'Visualization Workspace' at RSNANovember 28th 2022
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 Computed Tomography Study Shows High 20-Year Survival Rates for Early-Stage Lung CancerNovember 22nd 2022
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.
SPECT Imaging Agent Gets Expanded FDA Approval for Patients with Suspected Dementia with Lewy BodiesNovember 16th 2022
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.
Chest CT Study Suggests Marijuana Smokers May Have Higher Emphysema Risk Than Tobacco-Only SmokersNovember 15th 2022
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.
