Patient recovers language and motor function after 19 years
After 19 years in a minimally conscious state, a man recovered language and motor function. Diffusion tensor imaging showed reorganization of the patient's white matter, possibly facilitating functional recovery.
After 19 years in a minimally conscious state, a man recovered language and motor function. Diffusion tensor imaging showed reorganization of the patient's white matter, possibly facilitating functional recovery.
At the initial DTI evaluation by Henning U. Voss, Ph.D., a biomedical researcher at Cornell University, and colleagues, the patient already had regained limited movement, speech, and communication. DTI showed increased anisotropy (less water diffusion in white matter tracts, indicating recovery) in the medial parieto-occipital (MPO) areas compared with controls (J Clin Invest 2006;116:2005-2011).
Eighteen months later, at the time of a second scan, the patient's motor and cognitive functions had further improved. Interestingly, anisotropy in the MPO had decreased. Researchers theorize that the initial increase in anisotropy was a transitional stage of an ongoing axonal sprouting process. Once the new fiber tracts were laid down, anisotropy decreased as axons sprouted toward other targets.
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.
Study: AI-Generated ADC Maps from MRI More Than Double Specificity in Prostate Cancer Detection
June 5th 2025Emerging research showed that AI-generated ADC mapping from MRI led to significant increases in accuracy, PPV and specificity in comparison to conventional ADC mapping while achieving a 93 percent sensitivity for PCa.
