[Abstract] Objective: To explore the method of 3D CE-MRA in demonstrating arterial diseases from abdomen to lower extremity.Materials and Methods: Thirty patients underwent 3D CE-MRA at SIEMENS ESSENZA 1.5 T system with 3D-FLASH sequences and parallel acquisition technique using the body coil. All images were reconstructed with maximum intensity projection (MIP).Results: 3D CE-MRA could clearly show the vascular diseases from the abdomen aorta furcation to the foot artery. Of the 30 patients, 20 were found with arteriosclerosis obliterans, 2 with angeiomas, 1 with artery-vein malformation (AVM), 1 with arteriovenous fistula, 1 with variant artery abdomen to lower extremity arteries, 2 with iliac vein compression syndrome imaging. The CE-MRA images were normal in 3 patients.Conclusion: 3D CE-MRA is of great value for macroangiopathy detection, which can show the vascular illness, the relationship between illness and vessels, or relationship between vessels and peripheral tissues.
