We present the use of Double DANTE as an improved method for DANTE prepared 3D TSE imaging of intracranial arteries. DANTE preparation inherently leads to banding artifacts, which become increasingly visible at high-resolution imaging. We show that Double DANTE strongly reduces banding separation without changes in the DANTE pulse train duration, and more importantly, without compromising flow suppression of blood or CSF. Double DANTE therefore enables high-quality intracranial vessel wall MRI at 0.6mm isotropic resolution.
