Can MRI-Based Prostate Cancer Screening be a Viable Alternative to PSA Testing?
December 1st 2022In what may be the first study to assess the effectiveness of biparametric magnetic resonance imaging (MRI) for prostate cancer screening in a large cohort, researchers found that MRI screening had a significantly lower false positive rate and significantly higher positive predictive values (PPVs) than prostate-specific antigen (PSA)-based screening.
Can Emerging AI-Guided Software Rein in Scan Times for Cardiac MRI?
In a recent video interview, Raymond Y. Kwong, MD, discussed his clinical experience with the Vista.ai (formerly HeartVista) One Click MRI software and recent research, presented at the Radiological Society of North America (RSNA) conference, that revealed a 31 percent decrease in cardiac MRI scan times for patients with cardiomyopathy or structural heart disease.
New Ultrasound Study Shows Increased Liver Stiffness 10 Months After COVID-19 Infection
December 1st 2022The retrospective study involving the use of ultrasound shear wave elastography showed a significant increase in liver stiffness 44 weeks after the diagnosis of COVID-19 in comparison to pre-pandemic and pandemic controls.
Can Ultra-Low-Dose CT be Effective for Lung Cancer Screening in Current or Past Smokers?
Ultra-low-dose computed tomography (ULDCT) may have similar efficacy as low-dose CT (LDCT) for detecting a variety of pulmonary conditions in people with current or past smoking histories, but had poor detection of ground glass opacification lesions, according to a recent prospective study presented at the Radiological Society of North America (RSNA) conference.
Enhancing MRI Efficiency and Quality: Can the New SIGNA Experience Have an Impact?
Recently launched at the Radiological Society of North America (RSNA) conference, the SIGNA Experience reportedly features synergistic technologies and artificial intelligence (AI) advances that help improve the efficiency and quality of magnetic resonance imaging.
Deep Learning Model Predicts 10-Year Cardiovascular Disease Risk from Chest X-Rays
November 29th 2022Based on a single existing chest X-ray image, the deep learning model predicts future major adverse cardiovascular events with similar performance to an established risk scoring system and may help identify people for preventive use of statin medication.
What an MRI Study Reveals About Low Alcohol Use During Pregnancy and Fetal Brain Structure
November 28th 2022Researchers found that even low amounts of alcohol consumption in pregnant women can lead to early and diffuse structural changes in brain regions related to key functions including language development.
Philips Launches AI-Enabled 'Visualization Workspace' at RSNA
Offering more than 70 clinical applications, the next-generation edition of the Advanced Visualization Workspace reportedly includes enhanced liver analysis and artificial intelligence (AI)-powered scoring of early brain infarction noted on computed tomography (CT) scans for patients with ischemic stroke.
Ultra-High-Resolution MRI Identifies Enlarged Perivascular Spaces in People with Migraines
November 28th 2022New magnetic resonance imaging (MRI) research suggests a significant link between deep white matter hyperintensity severity and increased quantity of enlarged perivascular spaces in the centrum semiovale among people with migraines.
New Computed Tomography Study Shows High 20-Year Survival Rates for Early-Stage Lung Cancer
Emphasizing the benefits of annual lung cancer screening with low-dose computed tomography (CT), researchers noted high 20-year survival rates for a variety of early-stage lung cancer tumor presentations, including a 100 percent survival rate for those with non-solid or partly solid cancerous nodules.
Brain MRI Study Shows 'Significant Abnormalities' Up to Six Months After COVID-19
COVID-19 may cause changes in the brain stem and frontal lobe that could lead to fatigue, impacts in motor signal processing, insomnia, and depression, according to emerging research recently presented at the Radiological Society of North America (RSNA) annual conference in Chicago.
Emerging research showed the combination of contrast-enhanced ultrasound (CEUS) with perfluorobutane and modified 2017 LI-RADS criteria had comparable sensitivity, specificity, and accuracy to current magnetic resonance imaging (MRI) and computed tomography (CT) approaches to detecting hepatocellular carcinoma (HCC) lesions.
SPECT Imaging Agent Gets Expanded FDA Approval for Patients with Suspected Dementia with Lewy Bodies
GE Healthcare’s DaTscan is reportedly the first radiopharmaceutical tracer agent approved by the Food and Drug Administration (FDA) for use in patients with suspected dementia with Lewy bodies.
