Functional MRI uncovers neurobiology of dread
Functional MRI can differentiate between people who experience substantial dread of adverse experiences and those who don't, according to a study released by the National Institute on Drug Abuse.
Functional MRI can differentiate between people who experience substantial dread of adverse experiences and those who don't, according to a study released by the National Institute on Drug Abuse. Findings could provide new insights into the neurobiology of addictive behavior.
Emory University researchers used fMRI to map the brain activity of 32 healthy subjects anticipating unpleasant stimuli. The dread of waiting increased the blood flow in areas associated with attention rather than with fear. Dread may derive from the attention devoted to the expected physical response and not simply fear. Preliminary findings were published in Science.
MRI or Ultrasound for Evaluating Pelvic Endometriosis?: Seven Takeaways from a New Literature Review
September 13th 2024While noting the strength of MRI for complete staging of disease and ultrasound’s ability to provide local disease characterization, the authors of a new literature review suggest the two modalities offer comparable results for diagnosing pelvic endometriosis.
Diffusion-Weighted MRI and Neoadjuvant Chemotherapy for Rectal Cancer: What New Research Reveals
September 3rd 2024In a comparison of imaging assessments to gauge the effectiveness of neoadjuvant chemotherapy for rectal adenocarcinoma, researchers found the combination of diffusion-weighted imaging and MR tumor regression grading had a 90 percent area under the curve (AUC) and a negative predictive value (NPV) of 93 percent.
FDA Expands Clearance of MRI-Guided AI Platform for Deep Brain Stimulation and Lesioning Techniques
September 3rd 2024Utilizing a new machine learning model, the OptimMRI software may improve radiosurgery applications and lesioning techniques such as MRI-guided focused ultrasound through enhanced targeting of the inferolateral part of the ventral intermediate nucleus (VIM).
