Researchers found that a higher waist-to-hip ratio in midlife was associated with higher mean diffusivity in 26 percent of total white matter tracts in the cingulum as well as the superior and inferior longitudinal fasciculus.
Claustrophobia in Magnetic Resonance Imaging: An Analysis of Causes, Impacts and Solutions
January 18th 2024Given the frequent challenges in magnetic resonance imaging that are associated with claustrophobia, this author discusses innovations in noise reduction, radiofrequency coils and wide bore scanners, and emphasizes keys to relieving patient anxiety.
Newly FDA-Cleared Stereotactic System Can be Utilized with Pre-Op MRI or CT
January 17th 2024Utilized for neurological procedures including biopsies, catheter placement and electrode introduction, the SmartFrame OR Stereotactic System can be combined with preoperative MRI or CT to ensure optimal placement of devices and instruments.
FDA Clears Magnetic Resonance Spectroscopy Platform for Non-Invasive Assessment of Brain Chemistry
November 29th 2023BrainSpec Core reportedly offers enhanced sensitivity for low-grade gliomas and may facilitate the diagnosis of conditions including Alzheimer’s disease, multiple sclerosis, and epilepsy.
Study: Black Patients Less Likely Than Others to Receive MRI Assessment of Cognitive Impairment
November 27th 2023In a four-year study of over 1,600 patients who had outpatient head CTs, head CT angiography and/or brain MRI to assess cognitive impairment, researchers found that Black patients were over 9 percent less likely than White patients and over 16 percent less likely than Hispanic patients to receive brain MRI.
Could an Emerging AI System Lead to Earlier Autism Detection with DT-MRI?
November 21st 2023Through assessment of diffusion tensor MRI of the brain, a new AI system reportedly offers a 97 percent sensitivity rate in diagnosing autism in children between two to four years of age, according to research to be presented at the annual Radiological Society of North America (RSNA) conference next week.
Adjunctive Brain Volume Quantification Tool for MRI Gets FDA Clearance
November 14th 2023Providing automated brain volume calculations based on MRI images, NeuroShield’s artificial intelligence (AI)-powered technology may help facilitate treatment for neurodegenerative conditions ranging from Alzheimer’s disease to epilepsy.
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.
