Dear AuntMinnie MRI Insider,
Does menopause affect women's cerebral blood flow? Yes, according to a team of researchers from China, who have found via arterial spin labeling MRI that alterations in women's cerebral blood flow begin during perimenopause and appear to be due to an increased burden of white matter hyperintensities. These results may suggest ways postmenopausal women can be supported as their risk of cerebrovascular disease rises as they age. Check out our coverage of the team's review in this edition's featured article.
Once you've read that story, take a look at our report on a study indicating that risks associated with gadolinium-based contrast agents differ by drug and the importance of clinicians educating themselves about these differences. We're also highlighting research that outlines how global prostate MRI acquisition parameters vary widely around the world -- a trend that may not be good news for consistent patient care; a study that shows how a deep-learning algorithm based on MR images can differentiate spinal pathologies; and an analysis that outlines how MRI reveals novel clues to symptoms of long COVID.
On the women's imaging side, we're drawing attention to research that suggests that breast MRI offers a way to objectively measure background parenchymal enhancement -- which has been linked to increased breast cancer risk -- and a study that has found that most MRI screen-detected breast cancers are invasive.
