Multicenter Breast Ultrasound Study: AI Bolsters Accuracy and Specificity of BI-RADS ClassificationsMay 24th 2023
Emerging breast ultrasound research showed the use of computer-aided diagnosis (CAD), powered by deep learning, led to 24 percent and 36.9 percent improvements in accuracy and specificity, respectively, in the use of BI-RADS classifications by radiologists without breast ultrasound expertise.
Digital Mammography Meta-Analysis Suggests AI Performs as Well as RadiologistsMay 24th 2023
Six reader studies on digital mammography revealed a pooled sensitivity rate of 80.8 percent for stand-alone artificial intelligence (AI) in comparison to 72.4 percent for radiologist assessment while seven historic cohort studies showed a 75.8 percent pooled sensitivity rate for stand-alone AI versus 72.6 percent for radiologist interpretation of digital mammography.
Study Says CT Scan is More Predictive than Genetic Risk Factors for Coronary Heart Disease RiskMay 23rd 2023
In what may be the first comparative study of the polygenic risk score and the computed tomography (CT)-derived coronary artery calcium (CAC) score for assessing coronary heart disease (CHD) risk, researchers found that the CAC score was associated with significant improvements in assessing and stratifying risk for the development of CHD in middle-aged to older adults.
Key Findings on Non-Contrast CT Signal Higher Complication Risks in Patients with Intracerebral HemorrhageMay 22nd 2023
In a subgroup analysis of patients with intracerebral hemorrhage who had intraventicular hemorrhage (IVH) growth, researchers found that hypodensities on non-contrast computed tomography (CT) were associated with more than double the risk for greater than 1 mL of expanded IVH (eIVH).
Are You Prone to Superstitions in Radiology?May 22nd 2023
Whether it’s the proverbial “bad penny” case that crashes PACS or the perception that positive computed tomography angiography (CTA) exams for pulmonary arterial clots come in sets of three, suspicions can emerge here and there in radiology.
Can Abbreviated MRI Have an Impact in Neuroimaging?May 19th 2023
In a recently published review, radiology researchers from the University of Wisconsin discussed the potential and key considerations for applying accelerated magnetic resonance imaging (MRI) protocols in the assessment of emergent and urgent conditions.
What a Transvaginal Ultrasound Study Reveals About Fibroid Prevalence in Minority WomenMay 18th 2023
African American and Asian-Chinese women have a disproportionately higher prevalence of fibroids, according to newly published transvaginal ultrasound findings in a diverse population of nearly 1,000 women.
CT Study Examines Post-Reperfusion Infarction Growth in Vaccine-Naive Patients with COVID-19May 17th 2023
Unvaccinated people with COVID-19 who undergo angiographic reperfusion after acute ischemic stroke may have a greater than fivefold risk of continued infarct growth in comparison to unvaccinated people without COVID-19, according to computed tomography perfusion (CTP) and magnetic resonance imaging (MRI) findings from a recently published study.
Philips Introduces AI-Enhanced CT System for High-Volume Radiology Screening ProgramsMay 17th 2023
The artificial intelligence (AI)-enabled CT 3500 system reportedly reduces patient positioning time by 23 percent, improves low-contrast detectability by 60 percent and facilitates up to an 80 percent reduction in radiation dosing.
