MR oms in on brain structure changes
Scientists have known that meditation alters brain waves. New evidence suggests that the practice actually changes the brain's physical structure.
Scientists have known that meditation alters brain waves. New evidence suggests that the practice actually changes the brain's physical structure.
Dr. Sara W. Lazar and colleagues from Massachusetts General Hospital used MR imaging to assess the cortical thickness of 20 subjects experienced in meditation (Neuroreport 2005;16(17):1893-1897). Study participants averaged 40 minutes of meditation daily.
Compared with controls, meditation participants had thicker brain regions associated with attention, interoception (the automatic monitoring of heart rate or breathing), and sensory processing, including the prefrontal cortex and right anterior insula.
Between-group differences in prefrontal cortical thickness were most pronounced in older participants, suggesting that meditation might offset age-related cortical thinning.
Can Contrast-Enhanced Mammography be a Viable Screening Alternative to Breast MRI?
June 17th 2025While the addition of contrast-enhanced mammography (CEM) to digital breast tomosynthesis (DBT) led to over a 13 percent increase in false positive cases, researchers also noted over double the cancer yield per 1,000 women in comparison to DBT alone.
FDA Clears Enhanced MRI-Guided Laser Ablation System
June 5th 2025An alternative to an open neurosurgical approach, the Visualase V2 MRI-Guided Laser Ablation System reportedly utilizes laser interstitial thermal therapy (LITT) for targeted soft tissue ablation in patients with brain tumors and focal epilepsy.
Possible Real-Time Adaptive Approach to Breast MRI Suggests ‘New Era’ of AI-Directed MRI
June 3rd 2025Assessing the simulated use of AI-generated suspicion scores for determining whether one should continue with full MRI or shift to an abbreviated MRI, the authors of a new study noted comparable sensitivity, specificity, and positive predictive value for biopsies between the MRI approaches.
