The blood-oxygenation-level-dependent (BOLD) fMRI has been widely implemented to study brain functions. However, the BOLD contrast still suffers the low temporal resolution and low sensitivity. Here, we applied single carrier Wideband (WB) MRI technique on gradient echo imaging (GRE) sequence in fMRI studies, in order to reduce the scan time and enhance the T2* sensitivity. By examining the simulated BOLD contrast from different inhaled gas, this study demonstrated the reduced scan time and enhanced sensitivity of the Wideband MRI technique.
