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.
Current Insights and Emerging Roles for Contrast-Enhanced Mammography
May 10th 2024In a recent lecture at the 2024 ARRS Annual Meeting, Jordana Phillips, MD, discussed the role of contrast-enhanced mammography in staging breast cancer, evaluating response to neoadjuvant chemotherapy and recalls from screening.
MRI-Based Deep Learning Algorithm Shows Comparable Detection of csPCa to Radiologists
May 8th 2024In a study involving over 1,000 visible prostate lesions on biparametric MRI, a deep learning algorithm detected 96 percent of clinically significant prostate cancer (csPCa) in comparison to a 98 percent detection rate for an expert genitourinary radiologist.
Breast MRI and Dense Breasts: A Closer Look at Early Findings from a New Prospective Trial
May 2nd 2024Supplemental breast MRI had a cancer detection rate (CDR) of 20/1000 and a positive predictive value (PPV) of 50 percent, according to preliminary findings from a prospective trial involving women with heterogeneously or very dense breasts.
