Study Says MRI Offers Most Cost-Effective Imaging for Dizziness Presentations in the ER
November 10th 2023Noting that initial imaging sensitivity is a key factor in cost-effectiveness for patients who do not require acute treatment for dizziness, researchers found that specialized MRI (including multiplanar high-resolution DWI) provided the most benefit in a comparative trial of neuroimaging modalities.
Study Links PTSD to Higher Carotid Atherosclerosis and White Matter Hyperintensity in Midlife Women
November 6th 2023Ultrasound and MRI findings from a new study suggest that greater carotid atherosclerosis and elevated white matter hyperintensities among women with the APOEe4 genotype, a strong risk factor for Alzheimer’s disease, are associated with increased PTSD symptoms in midlife women.
Meta-Analysis of 83 MRI Studies Suggests Link Between Adversity Exposure and Mental Health Issues
November 3rd 2023In their review of functional MRI data from over 5,200 study participants, researchers noted that higher amygdala reactivity and lower prefrontal cortical reactivity were associated with adversity exposure, findings that may contribute to exaggerated threat detection and reduced emotional control.
Current and Emerging Perspectives on Contrast Media in Radiology
November 1st 2023In a recent video interview series, Dushyant Sahani, M.D., discussed the critical role of contrast media in diagnostic imaging, lessons learned from the contrast media shortage, key considerations with generic agents and currently unmet needs with contrast agents.
Large MRI Study Links High Proton Density Fat Fraction to Elevated Liver Disease Risks
October 27th 2023In a study of over 375,000 people, researchers found that a high liver MRI proton density fat fraction was associated with an over 7.5-fold higher risk for non-alcoholic steatohepatitis, a 4.5-fold higher risk for malignancy, and a 3.8-fold elevated risk for cirrhosis of the liver.
Can DWI MRI Offer a Viable Non-Contrast Alternative for Breast Cancer Assessment?
October 19th 2023In a newly published literature review, researchers examined the benefits of diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI) for breast cancer characterization and monitoring of neoadjuvant chemotherapy, current drawbacks that thwart wider adoption, and emerging techniques that may enhance the modality’s effectiveness.
FDA Clears AI-Enabled Denoising Feature for DWI Sequences on Portable Brain MRI System
October 9th 2023In reportedly the eighth FDA 510(k) clearance for Hyperfine’s Swoop portable brain MRI device, clinicians will now have access to enhanced denoising capabilities with diffusion-weighted imaging (DWI) sequences.
MRI Study Identifies Pelvic Floor Parameters that May Lead to Postpartum Stress Urinary Incontinence
October 2nd 2023Researchers found that the combination of a retrovesicourethral angle, functional urethral length, and bladder funnel on MRI exams in primiparous women had a 94.7 percent AUC for predicting postpartum stress urinary incontinence (SUI).
Mammography-Based Deep Learning Model Facilitates Higher Breast Cancer Detection on Screening MRI
September 22nd 2023New research suggests the capability of a mammography-based deep learning model to identify women at high risk of breast cancer led to more than triple the cancer detection rate on breast MRI in comparison to traditional risk assessment tools.
