'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.
New Review Reveals Flaws of Influential Canadian RCTs on Mammography Screening
March 29th 2022A closer look at the Canadian National Breast Screening Studies (CNBSS) has revealed key methodological flaws that may prohibit use of the findings in the development of future guidelines on mammography screening for breast cancer.
Key Highlights From the Annual Symposium of the American Society of Spine Radiology
March 23rd 2022In a recent video interview, Kevin J. Abrams, MD, discussed highlights from the recent 25th Annual Symposium of the American Society of Spine Radiology (ASSR), including lectures on imaging for spontaneous intracranial hypotension, the emergence of dynamic susceptibility contrast for MR perfusion and insights on the use of dual-energy computed tomography (CT) for diagnosing vertebral fractures.
Could an Emerging Classification Scheme Streamline Ovarian Cancer Detection on Pelvic Ultrasound?
March 22nd 2022Distinguishing between classic and non-classic presentations of isolated adnexal lesions on pelvic ultrasound reportedly had a high specificity and sensitivity in diagnosing ovarian cancer in women at average risk.
Study Offers Closer Look at AI-Enabled Tool for Assessing Breast Density
March 21st 2022The artificial intelligence (AI) model reportedly had an 89.3 accuracy rate in differentiating between non-dense and dense breasts on mammography scans, and a 90.4 percent rate of agreement with human radiologist reviewers.
Study Shows Link Between Breast Arterial Calcification and Significant Cardiovascular Risks
March 18th 2022While breast arterial calcification is a common incidental finding on mammograms that is not routinely recommended for follow-up, statistically significant associations with cardiovascular risks may change that approach for postmenopausal women.
Researcher Presents First Non-Invasive Images of Alpha-Synuclein in the Brain
March 16th 2022Emerging research suggests that an experimental alpha-synuclein (a-syn) positron emission tomography (PET) tracer may help diagnose multiple system atrophy (MSA) and potentially other neurodegenerative diseases such as Parkinson’s disease and Lewy body dementia.
Philips Garners FDA 501(k) Clearance for Update of Real-Time Clinical Surveillance Software
March 16th 2022New additions to the Philips Capsule Surveillance software include improved integration with health information technology (HIT) systems and enhanced visibility of patient data across remote devices.
New Chest Imaging Study Finds Intrathoracic Complications in 20 Percent of Patients with COVID-19
March 15th 2022The retrospective study, which involved nearly 1,000 patients with COVID-19, found that a high initial chest radiograph severity score was an independent risk factor for intrathoracic complications.
Multicenter Study Validates New MRI Scoring System for Peripheral Neuropathy
March 9th 2022In addition to facilitating strong interreader agreement among radiologists of various experience levels, use of the proposed Neuropathy Score Reporting and Data System (NS-RADS) classification for peripheral neuropathy reportedly improved accuracy in differentiating between milder and more severe categories for muscle abnormalities and nerve lesions.
Study Suggests Overdiagnosis in More Than 15 Percent of Mammography-Detected Breast Cancer Cases
March 4th 2022In a large study reviewing biennial mammography screening for women between the ages of 50 to 74, researchers estimated a 6.1 percent overdiagnosis rate for indolent pre-clinical cancer and a 9.3 percent overdiagnosis rate for progressive pre-clinical cancer in women who would have died from other causes prior to clinical diagnosis.
Could an AI-Powered Enhancement of MRI be a Pre-Op Game Changer for Total Shoulder Arthroplasty?
February 28th 2022A new artificial intelligence tool reportedly overcomes resolution issues of standard magnetic resonance imaging (MRI) scans with 3D images of the shoulder bones and may eliminate pre-operative use of computed tomography (CT) for total shoulder arthroplasty procedures.
Federal Judge Vacates IDR Provisions of the No Surprises Act
February 25th 2022The ruling noted that the interim final rule for the legislation materially altered the independent dispute resolution (IDR) process of the No Surprises Act and cited a lack of sufficient “notice and comment,” rendering the changes as unlawful as per the Administrative Procedure Act (APA).
New Study on Digital Breast Tomosynthesis Shows Benefits of Spot Compression Views
February 23rd 2022When there are equivocal findings with digital breast tomosynthesis (DBT), spot compression views may significantly enhance specificity and accuracy, and could reduce additional workup in benign cases.
