To reconstruct blood vessel in 2D and 3D MB TOF MRA without using coil sensitivity profile to reduce g-factor noise. The idea is to use CAIPRINHA on sparse angiographic data that first shift each slice/slab differently and then apply CAIPI reshift to shift each slab to its original position to form a continuous vessel tree. Results showed that the vessel reconstruction in 2D and 3D MB is comparable to standard single band MS TOF. Vessel reconstruction in MB angiography without using coil sensitivity profile can lead to high MB factors reducing the aquistion time and high sensitivity in detecting small vessels
