Featuring enhanced low-dose image quality with motion-free images, the Revolution Vibe CT system reportedly facilitates improved diagnostic clarity for patients with conditions ranging from in-stent restenosis to atrial fibrillation.
How Socioeconomic Disparities Affect Follow-Up of Incidental Pulmonary Nodules on CT
July 21st 2023In a study of nearly 2,500 patients with incidental pulmonary nodules (IPN) on chest computed tomography (CT) exams, 69.5 percent of those in the highest quartile of the CDC’s Social Vulnerability Index (SVI) had inappropriate IPN follow-up in comparison to 54.3 percent of those in the lowest quartile of the CDC SVI.
Study Says Photon-Counting CT Offers Better Lung Assessment than Conventional CT
July 12th 2023For conditions ranging from interstitial lung disease and post-COVID-19 complications to idiopathic pulmonary fibrosis, photon-counting computed tomography (PCCT) facilitates simultaneous functional and morphologic lung assessment at lower radiation dosing than conventional chest CT, according to newly published research.
Study: Photon-Counting CT for Pulmonary Angiography Allows Significant ICM Reduction
July 3rd 2023New research suggests the use of high-pitch photon-counting computed tomography (PCCT) facilitates similar image quality and attenuation in the pulmonary trunk at lower iodinated contrast media (ICM) dosing levels ranging from 35 to 60 ml.
Study Examines Photon-Counting CT for CAD Detection in Patients Having TAVR Procedures
June 20th 2023In a study cohort of patients undergoing pre-operative workup for transcatheter aortic valve replacement (TAVR), researchers found the use of photon-counting CT for ultra-high resolution coronary CT angiography had a 96 percent sensitivity rate and an 84 percent specificity rate for the detection of coronary artery disease (CAD).
What a Large CT Study Reveals About Potential Kidney Injury, Diabetes and Risk Stratification
June 7th 2023The 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.
What a New Meta-Analysis Reveals About CT Diagnosis of COVID-19
June 2nd 2023In a review of patient data from 42 countries, researchers found that standardized typical findings on computed tomography (CT) for COVID-19 had a pooled sensitivity rate of 70 percent and a pooled specificity rate of 90 percent.
Study Says CT Scan is More Predictive than Genetic Risk Factors for Coronary Heart Disease Risk
May 23rd 2023In what may be the first comparative study of the polygenic risk score and the computed tomography (CT)-derived coronary artery calcium (CAC) score for assessing coronary heart disease (CHD) risk, researchers found that the CAC score was associated with significant improvements in assessing and stratifying risk for the development of CHD in middle-aged to older adults.
CT Study Examines Post-Reperfusion Infarction Growth in Vaccine-Naive Patients with COVID-19
May 17th 2023Unvaccinated people with COVID-19 who undergo angiographic reperfusion after acute ischemic stroke may have a greater than fivefold risk of continued infarct growth in comparison to unvaccinated people without COVID-19, according to computed tomography perfusion (CTP) and magnetic resonance imaging (MRI) findings from a recently published study.
Philips Introduces AI-Enhanced CT System for High-Volume Radiology Screening Programs
May 17th 2023The artificial intelligence (AI)-enabled CT 3500 system reportedly reduces patient positioning time by 23 percent, improves low-contrast detectability by 60 percent and facilitates up to an 80 percent reduction in radiation dosing.
Study Shows Significant Incidental Findings in Nearly 34 Percent of Lung Screening CT Exams
May 11th 2023In a large retrospective study of 26,455 participants from the National Lung Screening Trial, low dose computed tomography (LDCT) exams revealed significant incidental findings (SIFs), ranging from emphysema to suspicious lesions, in 8,954 participants.
