Long-term data confirm stenting's cognitive benefit
For the first time, long-term data show sustained cognitive improvement at one year in patients who have undergone carotid stenting, according to a report from the 2007 International Symposium on Endovascular Therapy.
For the first time, long-term data show sustained cognitive improvement at one year in patients who have undergone carotid stenting, according to a report from the 2007 International Symposium on Endovascular Therapy. What's more interesting is that many asymptomatic patients in the study also showed improved cognitive functions following stenting.
This finding has led investigators to question the very notion of labeling these patients who are asymptomatic. The government currently reimburses only for symptomatic patients undergoing carotid stenting, according to Dr. Rodney Raabe, an interventional radiologist with Inland Vascular Institute in Spokane, WA.
"Symptomatic carotid stenosis may need to be redefined in the future to include functional deficits," Raabe said. "Perhaps potential neurocognitive improvement will be considered in carotid stenosis treatment."
Strategies to Reduce Disparities in Interventional Radiology Care
March 19th 2025In order to help address the geographic, racial, and socioeconomic barriers that limit patient access to interventional radiology (IR) care, these authors recommend a variety of measures ranging from increased patient and physician awareness of IR to mobile IR clinics and improved understanding of social determinants of health.
The Reading Room Podcast: Current Perspectives on the Updated Appropriate Use Criteria for Brain PET
March 18th 2025In a new podcast, Satoshi Minoshima, M.D., Ph.D., and James Williams, Ph.D., share their insights on the recently updated appropriate use criteria for amyloid PET and tau PET in patients with mild cognitive impairment.
Study: Monitoring of Prostate MRI Exams Could Lead to 75 Percent Reduction of Gadolinium Contrast
March 17th 2025While DCE MRI was deemed helpful in over 67 percent of cases in which it was used, researchers found that monitored prostate MRI exams, which facilitated a 75 percent reduction of DCE MRI sequences, had comparable sensitivity for prostate cancer as non-monitored exams.
