MR imaging unveils one source of dementia
Debate on the association between dementia and cerebrovascular disease is as old as imaging itself. Although the causes of dementia are multiple, some imagers consider cerebrovascular disease to be one of the most relevant.

Dr. Aart Spilt and colleagues at the University Medical Center of Leiden in the Netherlands explored the connection between structural brain damage and total cerebral blood flow. They prospectively enrolled 17 elderly patients with late-onset dementia, 16 subjects of the same age with normal cognitive function, and 15 young healthy controls. The study appeared in the September issue of Radiology.
Using MRI, the group found that elderly individuals with dementia exhibited significantly more structural brain damage and lower cerebral blood flow than normal subjects, even among the elderly.
"Clinicians should be aware that hypotension, as well as hypertension, needs to be prevented to diminish the periods with low cerebral blood flow," Spilt said.
New MRI Research Explores Links Between Waist-to-Hip Ratio and Memory in Aging
March 13th 2025Researchers found that a higher waist-to-hip ratio in midlife was associated with higher mean diffusivity in 26 percent of total white matter tracts in the cingulum as well as the superior and inferior longitudinal fasciculus.
Can Ultrasound-Based Radiomics Enhance Differentiation of HER2 Breast Cancer?
March 11th 2025Multicenter research revealed that a combined model of clinical factors and ultrasound-based radiomics exhibited greater than a 23 percent higher per patient-level accuracy rate for identifying HER2 breast cancer than a clinical model.
