Study Suggests AI is Superior to Sonographer Assessment of Heart Function on Echocardiograms
September 1st 2022In comparison to initial sonographer assessment of echocardiograms, cardiologists are over 10 percent less likely to change initial artificial intelligence (AI) assessment of left ventricular ejection fraction (LVEF), according to new research recently presented at the European Society of Cardiology Congress in Barcelona, Spain.
Addressing the Digital Divide with Annual Mammography Exams
September 1st 2022In a new study of over 7,200 women with no history of breast cancer, researchers found that women who scheduled health-care appointments online were more likely to have annual mammography exams but only 18 percent of the study population scheduled appointments online.
Screening Mammography and Breast Arterial Calcification: What a New Study Reveals
August 31st 2022Emerging research suggests a higher prevalence of positive breast arterial calcification (BAC) rates among Hispanic and Black women, and a lower rate of BAC in women with dense breasts or breast implants.
Is CT Imaging Overutilized in the ER?
August 30th 2022Emerging research findings suggest the use of single-encounter thoraco-abdominopelvic computed tomography (CT) per 1,000 trauma-related emergency department (ED) visits more than quadrupled for minor injuries and more than doubled for intermediate injuries from 2011 to 2018.
Judy Yee, MD, FACR Receives Gold Medal Honors from the Society of Abdominal Radiology
August 24th 2022Well known for her education and advocacy on the use of computed tomography (CT) colonography for colorectal cancer screening, Dr. Yee is also widely recognized for her leadership, mentoring skills and being a champion for diversity in the field of radiology.
Medicare Claims Study Shows Increasing Utility of PAs and NPs in Radiology Practices
August 23rd 2022In a new study comparing 2017 and 2019 Medicare claims submission data, researchers noted a 40 percent increase in evaluation and management (E&M) services, and a 74 percent increase in imaging services performed by radiology-employed nurse practitioners (NPs) and physician assistants (PAs).
Study Says Machine Learning MRI Model May Help Predict Recurrence Risk of Hepatocellular Carcinoma
August 22nd 2022Noting that the machine learning model incorporating magnetic resonance imaging (MRI) had a higher mean area under the curve (AUC) than a model based solely on clinical features for predicting hepatocellular carcinoma recurrence, researchers said the study findings could have implications for refining liver transplant criteria.
Emerging Deep Learning System May Enhance MRI Assessment of Intracranial Tumors
August 19th 2022In comparison to neuroradiology assessment of brain magnetic resonance imaging (MRI) scans for tumor diagnosis, researchers found that adjunctive use of a deep learning system improved diagnostic accuracy by 12.4 percent and sensitivity by 33.5 percent in one test set of 300 patients.
PET Imaging Study Links COVID-19 to Reduced Myocardial Flow Reserve
August 18th 2022Emerging research from a positron emission tomography (PET) study suggests that prior COVID-19 infection can lead to a 30 percent increased risk of lower myocardial flow reserve in patients with cardiovascular risk factors ranging from diabetes to coronary artery disease.
Study Finds Disparities with Follow-Up After Incomplete Mammography Exams
August 18th 2022Emerging research revealed that Asian patients, Black patients, and those who identified their race as “other” were nearly 1.5 times more likely than White women to have more than two-month delays with follow-up imaging after BI-RADS 0 screening mammography.
Survey: Over Half of Women in Their 40s Did Not Have a Mammogram in the Past Year
August 17th 2022In a recent survey of nearly 2,000 women in their 40s who had no history of breast cancer, researchers found that over 38 percent of survey respondents said they had no reason to get a mammogram or had never thought about it.
A Radiologist's Perspective on New Patient-Facing Breast Cancer Screening Guidelines
August 17th 2022With ongoing gaps in mammography screening and patient anxiety that often accompanies screening exams and a possible diagnosis of breast cancer, patient education is critical. Accordingly, in a recent video interview, Amy K. Patel, M.D., discussed the potential impact of new patient-oriented breast cancer screening guidelines from the National Comprehensive Cancer Network.
MRI/CT Imaging for Axillary Lymph Nodes: What a New Breast Cancer Study Reveals
August 16th 2022The combination of magnetic resonance imaging (MRI) and computed tomography (CT) had a 63.83 percent sensitivity rate for tumor-infiltrated axillary lymph nodes in patients with breast cancer in comparison to a 36.11 percent sensitivity rate for the combination of mammography and sonography.
Lung Cancer Screening Study Says Significant Disparities Persist Despite Expanded Eligibility
August 9th 2022While recent recommendations from the United States Preventive Services Task Force (USPSTF) to lower lung cancer screening thresholds significantly expanded eligibility for screening tests such as low-dose computed tomography (CT), differences in education, health-care insurance and proximity to health-care facilities continue to be key drivers of racial and socioeconomic disparities limiting access to appropriate preventive care.
FDA Clears New AI Software for MRI Detection of Prostate Cancer
August 8th 2022The ProstatID, an adjunctive artificial intelligence software that radiologists can utilize with traditional magnetic resonance imaging (MRI), reportedly measures prostate gland volume, and suggests PI-RADS scoring of suspicious lesions.
Can EHR Interventions Have an Impact in Conserving Iodinated Contrast Media in Radiology?
August 3rd 2022A recent study found the use of an alert and a request for more clinical information in a multisite health system’s electronic health record (EHR) system led to a 12 percent reduction in contrast-enhanced computed tomography (CT) exams per day and a 15.2 percent reduction in orders for CT with contrast media per day.
Could AI Enhance Early Detection of COVID-19 on Chest X-Rays?
August 2nd 2022Preliminary research revealed an area under the curve (AUC) of 85 percent for an artificial intelligence (AI) algorithm in diagnosing COVID-19 on initial chest X-rays in comparison to a consensus 71 percent AUC for five radiologists.
Study Suggests AI Enhances Non-Contrast CT Detection of Large Vessel Occlusion
July 29th 2022Artificial intelligence (AI) accurately diagnosed 79 percent of proximal large vessel occlusions with an ipsiversive gaze deviation on non-contrast computed tomography (CT), according to new research findings presented recently at the Society of Neurointerventional Surgery’s (SNIS) 19th Annual Meeting in Toronto.
