We demonstrate three alternative combination to obtain two different dynamic data in one MR examination. A combination of 4D-MRA and DSC-MRI (MR perfusion) is considered for patients with cerebral occlusive vascular disease. Another combination involves acetazolamide (ACZ) loading. DSC-MRI can be performed before and after ACZ administration. For brain tumor cases, a combination of a T1W dynamic study (DCE-MRI) and DSC-MRI can be used.
