3D FLAIR TSE imaging can effectively inhibit cerebrospinal fluid flow artifacts, but the scanning time is long, affecting clinical application. Compressed sensing (CS) is a technique to accelerate the acquisition of magnetic resonance imaging (MRI) by using sparsity constraints during readout measurements of k-space. This study aimed to compare the cerebrospinal fluid flow artifacts and overall image quality in CS 3D FLAIR TSE imaging combined and in 2D FLAIR TSE imaging. Results showed that CS 3D FLAIR TSE yielded better image quality, enhanced diagnosis performance, and reduced fluid flow artifacts when compared to the traditional 2D FLAIR TSE sequence.
