MRI reveals when cognitive impairment will advance
Swiss researchers used susceptibility-weighted MRI and an artificial intelligence technique to help identify which individuals with mild cognitive impairment will continue to decline.
Swiss researchers used susceptibility-weighted MRI and an artificial intelligence technique to help identify which individuals with mild cognitive impairment will continue to decline.
Susceptibility-weighted MRI measures magnetic susceptibility phase-effect differences between tissues. Using the technique, researchers were able to view details of the blood vessels in the brain, including microhemorrhages and microbleeds.
The scans revealed microbleeds in 33% subjects with stable mild cognitive impairment. They found microbleeds in 54% of those with progressive cognitive impairment and in 14% of the control group. The study appeared in Radiology.
The researchers also analyzed the data with support vector technology algorithms to identify patterns within a group and create classifications. By adding the support vector technology to the baseline MRI data the researchers were able to distinguish patients with mild cognitive impairment with 85% accuracy.
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.
