Magnetic resonance imaging apparatus and method controlling execution of a pulse sequence based on recovery of longitudinal magnetization of a monitor region
First Claim
1. A magnetic resonance imaging apparatus comprising:
- processing circuitry configured to execute a pulse sequence to acquire data from an image taking region after applying a first pre-pulse to the image taking region in synchronization with a predetermined electrocardiographic waveform of a subject, whereinthe processing circuitry is further configured to;
acquire data from a monitor region that is different from the image taking region after applying a second pre-pulse to the monitor region, by using timing linked with timing with which the first pre-pulse is applied;
monitor a degree of recovery of longitudinal magnetization in the data acquired from the monitor region; and
control execution of the pulse sequence in accordance with the degree of recovery of longitudinal magnetization.

Abstract
A Magnetic Resonance Imaging apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to execute a pulse sequence to acquire data from an image taking region after applying a pre-pulse in synchronization with a predetermined electrocardiographic waveform of the subject. The processing circuitry is configured to monitor recovery of longitudinal magnetization by acquiring data from a monitor region that is different from the image taking region, by using timing linked with the timing with which the pre-pulse is applied. The processing circuitry is configured to control execution of the pulse sequence on the basis of a signal value of the data from the monitor region.
