SHORT T2 TISSUE IMAGING WITH T2 PREP PETRA SEQUENCE

摘要

In a short T2 tissue imaging method and system, a magnetic resonance image is acquired that includes a short T2 tissue based on point-wise encoding time reduction with radial acquisition point-wise encoding time reduction with radial acquisition (PETRA) sequences, to obtain a first image, a T2 preparation pulse cluster is applied for suppressing a short T2 tissue signal between the PETRA sequences according to a predetermined interval of applying the T2 preparation pulse cluster, a magnetic resonance image is acquired that excludes the short T2 tissue based on the PETRA sequences applied with the T2 preparation pulse cluster, to obtain a second image; and a magnetic resonance image of the short T2 tissue is obtained based on the second image and the first image (e.g. by subtracting the second image from the first image).
