Emerging Perspectives on Computed Tomography Colonography
May 13th 2022In recent video interviews, Syam Reddy, MD, Judy Yee, MD and Anand Narayan, MD, discussed various benefits of computed tomography colonography (CTC) for colorectal cancer screening, the underutilization of the CTC procedure and steps moving forward to improve access to this procedure.
Iodinated Contrast Media: 15 Recommendations for Addressing the Shortage
May 12th 2022Given the challenges with the shortage of the iodinated contrast agent Omnipaque, national and state organizations have issued suggested risk mitigation and conservation strategies to reprioritize imaging needs during this temporary shortage.
Diagnosing Cardiac Ischemia in Women: Key Imaging Considerations
May 10th 2022Sharing insights from their recent presentation at the American Roentgen Ray Society (ARRS) conference in a new video interview, researchers discussed how sex-based differences have an impact in the imaging and diagnosis of ischemic heart disease (IHD) in women.
New Study Shows Impact of COVID-19 and Comorbidities in Inner-City Lung Screening Cohort
May 1st 2022In a lung screening cohort of over 2,500 people, researchers found that significantly higher rates of chronic kidney disease and chronic heart failure were associated with increased hospitalization and mortality rates in patients with COVID-19.
ER Imaging Study Looks at Possible Complications of COVID-19 Vaccines
May 1st 2022Lung opacities/consolidation and cervical/axillary adenopathy are reportedly common findings in emergency room imaging of patients suspected of having complications related to COVID-19 vaccines, according to new research presented at the American Roentgen Ray Society (ARRS) conference.
Issues and Answers With Outsourced Teleradiology Night Coverage
April 28th 2022While there can be an array of challenges in outsourcing night coverage to teleradiology service providers, due diligence with contract terms can help mitigate costs and increase flexibility if radiology practices decide to switch teleradiology providers down the line.
Can AI-Powered Mammography Screening be a Game Changer?
April 25th 2022In a retrospective study involving mammography screening in over 114,000 women, researchers found that an artificial intelligence model had comparable specificity and sensitivity to radiologist screenings, reduced false positive results by 25 percent and reduced radiologist workload by more than 62 percent.
Has Burnout Become an Epidemic in Radiology?
April 22nd 2022Emerging literature suggests a seemingly insurmountable wave of physician burnout in radiology. While the recently enacted Dr. Lorna Breen Health Care Provider Protection Act offers the promise of increased awareness, education, and funding to help prevent burnout, an increased commitment and flexibility from institutional leadership may also be key to erasing stigmas and driving meaningful change.
Can Deep Learning Ultrasound Assessment be a Viable Option for Diagnosing Ovarian Cancer?
April 20th 2022A new study suggests that deep learning algorithms with multimodal ultrasound have comparable specificity and sensitivity to subjective expert assessment and use of the O-RADS classification to distinguish between benign and malignant ovarian tumors.
Multicenter Study Assesses Intrasaccular Flow Disruption for Treating Sidewall Aneurysms
April 19th 2022Emphasizing the proper diagnostic characterization of sidewall aneurysms, the authors of a new study found no significant differences in occlusion status or complications when they compared the approved use of intrasaccular flow disruption for bifurcation aneurysms to off-label treatment of sidewall aneurysms.
FDA Issues Advisory on Use of AI and Machine Learning for Large Vessel Occlusion in the Brain
April 15th 2022The advisory emphasizes that the computer-aided triage and notification (CADt) devices, many of which incorporate artificial intelligence (AI) or machine learning technology, are intended to aid radiologists in prioritizing the assessment of brain imaging that may reveal signs of large vessel occlusion (LVO).
'A Call to Arms' for Electronic Transfer of Medical Images Between Institutions
April 12th 2022In a recent video interview, Arun Krishnaraj, MD, MPH and David Larson, MD, MBA, discussed the continued use of physical media to transport medical images between different health-care facilities, resulting inefficiencies and delays with patient care, and the initiative to create a linked multi-hub model to end this dated practice once and for all.
ACR Urges CMS to Reconsider Non-Coverage of Computed Tomography Colonography (CTC)
April 7th 2022In a formal request to the Centers for Medicare and Medicaid Services (CMS), the American College of Radiology (ACR) emphasized that Medicare and Medicaid coverage of computed tomography colonography (CTC) could significantly improve colorectal cancer screening rates for at-risk populations.
Could a Deep Learning System Facilitate the Diagnosis of Type 2 Diabetes on Abdominal CT?
April 7th 2022Employing a deep learning system for pancreatic segmentation, researchers found that intrapancreatic fat percentage and pancreatic fractal dimension were among the key predictors for type 2 diabetes mellitus in a multivariable analysis.
Fracture Detection: Study Suggests AI Assessment May Be as Effective as Clinician Assessment
April 1st 2022The authors of a new meta-analysis found no significant differences between clinicians and artificial intelligence in diagnosing fractures but conceded that slightly over half of the studies assessed had a high risk of potential bias.
