MR-detected brain atrophy predicts decline in elderly
Cognitively healthy elderly people who experience atrophy in the amygdala and hippocampus are more likely to develop dementia, according to a study in the January Archives of General Psychiatry.
Cognitively healthy elderly people who experience atrophy in the amygdala and hippocampus are more likely to develop dementia, according to a study in the January Archives of General Psychiatry.
Dr. Tom den Heijer and colleagues of the Erasmus Medical Center in Rotterdam used MRI to assess the brain volumes of 511 dementia-free elderly subjects in the Rotterdam Study, a large population-based cohort study that began in 1990.
Over the six-year follow-up period, 35 participants developed dementia, and 26 of those were diagnosed with Alzheimer's disease. Volume reductions between 5% and 17% were strongly associated with the development of dementia, according to the study. In participants with mild to moderate AD, volume reduction rates were between 25% and 40%, suggesting that atrophy rates accelerate in patients with AD.
Seven Takeaways from New CT and MRI Guidelines for Ovarian Cancer Staging
January 20th 2025In an update of previous guidelines from the European Society of Urogenital Radiology published in 2010, a 21-expert panel offered consensus recommendations on the utility of CT, MRI and PET-CT in the staging and follow-up imaging for patients with ovarian cancer.
Can Generative AI Facilitate Simulated Contrast Enhancement for Prostate MRI?
January 14th 2025Deep learning synthesis of contrast-enhanced MRI from non-contrast prostate MRI sequences provided an average multiscale structural similarity index of 70 percent with actual contrast-enhanced prostate MRI in external validation testing from newly published research.
Can MRI Have an Impact with Fertility-Sparing Treatments for Endometrial and Cervical Cancers?
January 9th 2025In a literature review that includes insights from recently issued guidelines from multiple European medical societies, researchers discuss the role of magnetic resonance imaging (MRI) in facilitating appropriate patient selection for fertility-sparing treatments to address early-stage endometrial and cervical cancer.
