Micheal Casasnovas[email protected]Digital X-RayTargeted renal therapy offers a solution to contrast allergic reactionsRadiologists aren't the only ones who must grapple with contrast-induced allergic reactions: Endovascular therapy specialists may see their choices for imaging exams limited by issues such as contrast-induced nephropathy and hypersensitivity to gadolinium, according to an imaging expert from Columbia University. But the use of targeted renal therapy may reduce the incidence of contrast-induced nephropathy.February 18, 2008Page 1 of 1Top StoriesMolecular ImagingWhole-body PET shows how naloxone blocks opioidsPET imaging has shown for the first time how the opioid overdose treatment naloxone blocks neuroreceptors throughout the body.Womens ImagingKomen rails against proposed federal cuts to women's health programCTCT muscle metrics could help screen for sarcopeniaWomens ImagingCancer incidence on rise in younger people, womenAssociationsFinancial shock waves strike close to radiology researchers
![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)
