In a study of women with oligometastatic breast cancer, the use of 18F-FDG PET/CT detected additional metastases in one-third of cases that were not evident on conventional CT.
New Dual-Source CT Device May be Cost-Effective Alternative for Smaller Facilities
November 16th 2023Offering a combination of simplified and personalized scanning for patients at significantly lower lifecycle costs than other dual-source CT systems, the Somatom Pro.Pulse may be a viable option for smaller rural facilities and outpatient imaging centers.
Is Surveillance Imaging Necessary After Primary Radiation for Head and Neck Cancer?
November 13th 2023For patients who had a complete metabolic response to radiation treatment for head and neck cancer, the authors of a recent study found that surveillance imaging with PET/CT, MRI or CT did not improve outcomes in comparison to expectant management.
CT News: American Cancer Society Issues Updated Lung Cancer Screening Recommendations
November 2nd 2023In a newly updated guidance, the American Cancer Society recommends the expansion of annual lung cancer screening with low-dose computed tomography (LDCT) for current or previous smokers 50 to 80 years of age who have a 20-pack-year or greater history of smoking.
Annalise ai Introduces Radiology Triage Platform for Head CT and Chest X-Ray Exams
November 1st 2023Featuring 12 prior FDA clearances for chest X-ray and non-contrast head CT, the Annalise Triage platform may help streamline radiology workflows and prioritize timely diagnosis of urgent conditions.
Current and Emerging Perspectives on Contrast Media in Radiology
November 1st 2023In a recent video interview series, Dushyant Sahani, M.D., discussed the critical role of contrast media in diagnostic imaging, lessons learned from the contrast media shortage, key considerations with generic agents and currently unmet needs with contrast agents.
Current Concepts with Advances in Photon-Counting Computed Tomography
October 26th 2023Photon-counting computed tomography (PCCT) offers a number of salient advantages over conventional CT, including improved image resolution and contrast-to-noise ratio, enhanced denoising capability and inherent spectral sensitivity.
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.
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.
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.
