A novel image fusion visualizes the angioarchitecture of the perforating arteries in the brain.
We report a novel technique that fuses 3D digital subtraction angiograms and MR images. Image fusion was successfully performed within 20 minutes each in 11 consecutive cases. Our initial experience showed that this image fusion enabled clear and simultaneous visualization of perforating arteries and surrounding tissues. The relation between perforating arteries and normal brain or lesions was easily understood in a clinical setting by using this image fusion.
