Feasibility of high resolution 3D fMRI with whole brain coverage

In high resolution fMRI studies, higher SNR is always desired. Although using a surface coil can increase the SNR, it will limit the study to a certain area of the brain. The 3D method has increased SNR compared to that of the 2D method. However it suffers from low temporal resolution especially when whole-brain coverage is wanted and multi-shot spirals are used to achieve the high in-plane resolution. This problem can be mitigated by using the UNFOLD technique. In this work, we showed the feasibility of high resolution fMRI studies over the whole brain with a reasonable temporal resolution.
