A New Magnetic Resonance Imaging Method for 2 Tissue Suppression: Double Tissue Suppression With Multiecho Acquisition and Single Inversion Time Combining High-Intensity Reduction (DOMUST-HIRE).

Introduction: The fluid-attenuated inversion recovery (FLAIR) method is one of the most important magnetic resonance imaging techniques for the brain, and the high-intensity reduction (HIRE) method is an imaging technique to obtain cerebrospinal fluid suppression images by subtracting long echo time images from short echo time images. In contrast, the double inversion recovery technique suppresses 2 types of tissue signals with different T1 values by applying 2 inversion recovery pulses with different inversion times. However, the double inversion recovery method requires the setting of 2 inversion times in a sequence; thus, its use is limited to relatively high-specification equipment.
