Carotid stenting brings mental pep
Stenting of the carotid artery may offer more than reduced stroke risk, especially to patients with impaired brain perfusion. Researchers have found that the procedure improves cognitive speed, verbal fluency, and delayed recall.
Stenting of the carotid artery may offer more than reduced stroke risk, especially to patients with impaired brain perfusion. Researchers have found that the procedure improves cognitive speed, verbal fluency, and delayed recall.
"To my knowledge, this is the first study combining neuropsychological testing and perfusion imaging that screens for silent ischemic stroke events that can occur during stenting," said lead investigator Dr. Iris Q. Grunwald, a consultant at Saarland University Clinic in Homburg, Germany, at the RSNA meeting.
After evaluating 26 patients, researchers found a statistically significant increase in cognitive speed following stenting, regardless of the patient's age or the severity of stenosis. Results also indicated a correlation between the degree of stenosis and the ipsilateral perfusion deficit. Patients with perfusion deficits experienced improved memory function after stenting restored blood flow.
FDA Clears Virtually Helium-Free 1.5T MRI System from Siemens Healthineers
June 26th 2025Offering a cost- and resource-saving DryCool magnet technology, the Magnetom Flow.Ace MRI system reportedly requires 0.7 liters of liquid helium for cooling over the lifetime of the device in contrast to over 1,000 liters commonly utilized with conventional MRI platforms.
Multinational Study Reaffirms Value of Adjunctive AI for Prostate MRI
June 16th 2025The use of adjunctive AI in biparametric prostate MRI exams led to 3.3 percent and 3.4 percent increases in the AUC and specificity, respectively, for clinically significant prostate cancer (csPCa) in a 360-person cohort drawn from 53 facilities.
FDA Clears Enhanced MRI-Guided Laser Ablation System
