Abstract

According to one embodiment, an MRI apparatus includes sequence control circuitry and processing circuitry. The sequence control circuitry executes a pulse sequence for collecting MR signals in collection timings along a relaxation curve of longitudinal magnetization in synchronization with heartbeats or blood beats. The processing circuitry generate a T1 map representing a distribution of T1 values by using the collected MR signals. The pulse sequence is set so as not to collect any MR signal in at least one heartbeat or blood beat among heartbeats or blood beats included between first and second inversion pulses, and so as to collect an MR signal in a heartbeat or blood beat subsequent to the at least one heartbeat or blood beat in which no MR signal is collected.
