Richard Stevenson[email protected]Clinical NewsIntense x-rays expose Alzheimer's diseaseA challenge in Alzheimer's disease treatment is that conventional tools such as MRI cannot resolve the micrometer-sized changes in the brain associated with the illness. However, these tiny features can now be identified with diffraction-enhanced imaging, with the potential to delivery early diagnosis, according to U.S. researchers.August 5, 2009Page 1 of 1Top StoriesAssociationsFinancial shock waves strike close to radiology researchersAs of May 6, U.S. institutions have lost almost $2 billion in NIH funding.

![Images depict axial MRI scans in a 50-year-old premenopausal female patient with biopsy-proven 12-mm invasive lobular cancer in the lower outer quadrant of the left breast. Upper images are subtracted dynamic contrast-enhanced (DCE) MRI scans from the first and second postcontrast acquisitions. Lower images are ultrafast MRI scans obtained within 24 hours after the DCE study (four consecutive subtracted dynamic frames from time points [T] 6–9). There is marked background parenchymal enhancement (BPE) on the DCE MRI scans. Thus, the known cancer (arrow) is barely visible; it exhibits only slightly stronger enhancement than the normal fibroglandular tissue, which results in low conspicuity. At ultrafast MRI there is less BPE, and still the cancer is barely visible because it starts to enhance simultaneously with the BPE. The conspicuity of the cancer is even reduced compared with the DCE series. Both of the readers missed this cancer on both the DCE and ultrafast MRI scans.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2025/05/2025-05-06-rsna-ultrafast-dce-mri-breast.Gzvq76udFr.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
