fMRI bolsters diagnosis, management of autism
Functional MRI can identify brain activity patterns unique to people with autism spectrum disorders. Findings suggest that quantitative fMRI-based measurements could improve the diagnosis and treatment of these conditions.
Principal investigator Pearl H. Chiu, Ph.D., an assistant professor of neuroscience at Baylor College of Medicine in Houston, and colleagues asked high-functioning people with ASD and normal subjects to play an interpersonal game that involved social trust as they underwent fMR scans. The investigators found that the pattern of activity in the cingulate cortex of people with ASD indicated a diminished perception of themselves in a social interaction. This activity pattern resembled one seen in normal people when they play against a computer. Researchers published findings in the Feb. 7 issue of Neuron.
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.
