A method, which is performed by an MRI apparatus, of scanning a blood vessel, includes: sequentially applying, according to a time-of-flight (TOF) method, radio frequency (RF) pulses respectively to first grouped slabs during a first repetition time (TR) sequentially acquiring MR signals respectively corresponding to the RF pulses applied during the first TR sequentially applying, according to the TOF method, RF pulses respectively to second grouped slabs during a second TR and sequentially acquiring MR signals respectively corresponding to the RF pulses applied during the second TR.
