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.
Large MRI Study Links High Proton Density Fat Fraction to Elevated Liver Disease Risks
October 27th 2023In a study of over 375,000 people, researchers found that a high liver MRI proton density fat fraction was associated with an over 7.5-fold higher risk for non-alcoholic steatohepatitis, a 4.5-fold higher risk for malignancy, and a 3.8-fold elevated risk for cirrhosis of the liver.
Can AI Improve Triage Efficiency in Radiology Workflows for Follow-Up X-Rays?
October 24th 2023An emerging deep learning algorithm can reportedly triage 40 percent of no-change X-rays while providing 88 to 90 percent accuracy for detecting changes with X-rays obtained in the emergency department and intensive care unit at a tertiary referral hospital, according to recently published research.
Can ChatGPT be an Effective Patient Communication Tool in Radiology?
October 20th 2023While ChatGPT has the potential to help streamline responses to imaging-related questions from patients, the authors of a new study found that a third of ChatGPT responses to unprompted questions on medical imaging were not “fully relevant.”
Can DWI MRI Offer a Viable Non-Contrast Alternative for Breast Cancer Assessment?
October 19th 2023In a newly published literature review, researchers examined the benefits of diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI) for breast cancer characterization and monitoring of neoadjuvant chemotherapy, current drawbacks that thwart wider adoption, and emerging techniques that may enhance the modality’s effectiveness.
Can Deep Learning Bolster CT Detection and Classification of Usual Interstitial Pneumonia?
October 18th 2023In a multicenter cohort of patients with interstitial lung disease (ILD), a deep learning classification tool demonstrated an 81 percent sensitivity rate and a 77 percent specificity rate for predicting usual interstitial pneumonia on computed tomography (CT) scans.
Mammography News: FDA Clears AI Software for Breast Arterial Calcification Detection
October 17th 2023Utilized in conjunction with screening digital mammography or digital breast tomosynthesis (DBT), the artificial intelligence (AI)-powered software cmAngio may help detect and localize breast arterial calcification (BAC), an incidental finding that has been linked to an elevated risk for heart disease and stroke.
What Does the Future Hold for Medicare Coverage of Amyloid PET Scans?
October 16th 2023Various organizations have applauded the decision by the CMS to remove National Coverage Determination (NCD) limitations to coverage for amyloid PET scans, including the limitation of Medicare or Medicaid coverage to one PET scan per a patient’s lifetime. It remains to be seen, however, how coverage decisions will be made by local Medicare Administrative Contractors (MACs).
Multinational Study Suggests High Variability with Quality of Prostate MRI
October 12th 2023In a study of 355 multiparametric prostate MRI exams from a total of 71 scanners from 41 facilities in 18 countries, researchers found that only 23 scanners achieved a PI-QUAL score of 5 for optimal image quality.
OsteoSight Gets FDA Breakthrough Device Designation for Bone Mineral Density Assessment on X-Rays
October 10th 2023By leveraging subtle signals on routine X-rays to assess bone mineral density (BMD), the technology may facilitate earlier detection of osteoporosis and help prevent fragility fractures.
FDA Clears AI-Enabled Denoising Feature for DWI Sequences on Portable Brain MRI System
October 9th 2023In reportedly the eighth FDA 510(k) clearance for Hyperfine’s Swoop portable brain MRI device, clinicians will now have access to enhanced denoising capabilities with diffusion-weighted imaging (DWI) sequences.
Emerging Insights in Diagnosing Recurrent Prostate Cancer in Men with Low PSA Levels
October 7th 2023In a recent video interview, Ashesh Jani, M.D., discussed a subset analysis from the SPOTLIGHT trial that examined the utility of the PET PSMA agent flotufolastat F 18 (Posluma) for detecting prostate cancer recurrence in men with low PSA levels lower than 1 ng/mL.
GE HealthCare Adds Real-Time AI Guidance to Venue Family Ultrasound Systems
October 6th 2023Geared to clinicians who may lack ultrasound expertise, the artificial intelligence (AI)-powered Caption Guidance technology reportedly provides stepwise instruction for acquiring optimal cardiac ultrasound images.
Multicenter Study Cites Benefits of Ultrasound-Guided Carpal Tunnel Release
October 6th 2023In a study of over 500 people with carpal tunnel syndrome, researchers found that 57 percent returned to work three days after being treated with UltraGuideCTR, a modality which enables real-time ultrasound guidance for carpal tunnel release.
Study Shows Mixed Results with AI Software for PE Detection on CTPA Scans
October 5th 2023While the artificial intelligence (AI) triage system significantly reduced wait times for computed tomography pulmonary angiography (CTPA) results that were positive for pulmonary embolism (PE), researchers found no significant differences in the use of adjunctive AI with respect to accuracy rates and specificity rates.
