Incorporating dynamic contrast-enhanced MRI, a deep learning model demonstrated a 20 percent higher AUC in external validation testing than clinical factors alone and over a 17 percent higher AUC than radiological factors alone in predicting proliferative hepatocellular carcinoma (HCC).
AI Can Improve Tumor Mapping, Aid Patient Counseling in Focal Therapy for Prostate Cancer
August 31st 2023Wayne G. Brisbane, MD, of the University of California, Los Angeles, discussed the challenges of focal therapy for prostate cancer and how Unfold AI can help improve the accuracy of this treatment, as well as help counsel patients during the treatment decision process.
Study Reveals Tradeoffs Between Contrast-Enhanced Mammography and MRI for Supplemental Screening
August 16th 2023In a new study comparing standard breast MRI, abbreviated breast MRI and contrast-enhanced mammography in supplemental breast cancer screening, researchers found that MRI offered a greater than 14 percent higher cancer detection rate and a nearly 39 percent higher sensitivity rate than CEM.
MRI Study: Half-Dose Gadopiclenol Offers Similar Visualization and Safety as Full-Dose Gadobutrol
July 20th 2023Newly published research suggests the use of gadopiclenol at 0.05 mmol/kg is non-inferior to gadobutrol 0.1 mmol/kg for all qualitative visualization parameters on full-body magnetic resonance imaging (MRI).
FDA Clears Conditional MRI Use for Implantable Sleep Apnea System
May 26th 2023Conditional use of full-body magnetic resonance imaging (MRI) is reportedly permitted for patients using any of the models for the remede® System, an implantable nerve stimulation therapy indicated for the treatment of adults with moderate to severe central sleep apnea.
New ACR Guidelines Emphasize Earlier Mammography Screening for High-Risk Women
May 4th 2023While calling for a universal breast cancer risk assessment by the age of 25, the American College of Radiology (ACR) emphasized that ascertaining screening needs prior to the age of 40 is particularly important in high-risk populations such as Black women, who are 42 percent more likely to die from breast cancer in comparison to non-Hispanic White women.
Can Alternative MRI Techniques Help Enhance CyberKnife Treatment Imaging?
May 4th 2023In a review of the literature, this author discusses the viability of artificial intelligence (AI), parallel imaging, compressed sensing and simultaneous multi-slice excitation for improving the scan times and use of magnetic resonance imaging (MRI) to facilitate CyberKnife treatment.
Could Controlled Imaging Rein in Suboptimal Use of MRI, CT and Ultrasound Exams?
April 24th 2023Lamenting a lack of control over imaging requests from referring clinicians, this author suggests that a more collaborative approach between referrers and radiologists may facilitate more efficient use of imaging.
