  1. Repetition Time
    • According to 3 sources
    TR (Repetition Time) in Magnetic Resonance Imaging (MRI) is the time interval between successive pulse sequences applied to the same slice. Specifically, TR is the duration between the application of one RF (radiofrequency) pulse and the next.
    The repetition time (TR) is the length of time between corresponding consecutive points on a repeating series of pulses and echoes.
    The repetition time (TR) is the time from the application of an excitation pulse to the application of the next pulse. It determines how much longitudinal magnetization recovers between each pulse. It is measured in milliseconds.
