Ferumoxytol-enhanced MRA is safe for chronic kidney disease patients

January 29, 2025

Ultrafast and standard MRI in a 30-year-old woman with triple-negative invasive ductal carcinoma. (A) Ultrafast MRI taken 16.8 seconds after contrast agent injection. (B) Standard MRI taken 58.8 seconds after contrast agent injection. Both images show an oval-shaped, irregular marginated, rim-enhancing mass in the left outer breast. For 3D tumor segmentation, the entire enhanced tumor margins were drawn from top to bottom of each tumor in axial views of U2 phase postcontrast ultrafast MRI and the initial phase postcontrast standard MRI. Among the 14 ultrafast images, U1 is the first phase in which the signal intensity of the hotspot region of interest of the tumor is 10% higher than the average signal intensity of unenhanced images. U2 is the immediate next phase of U1 and the well-established tumor enhancement time.
