N2 - Objective The aims of this study were to compare isotropic 3-dimensional fat-suppressed T2-weighted fast spin echo (FSE) imaging (T2FS) with 2-dimensional fat-suppressed proton-density-weighted FSE imaging (2D-PDFS) and evaluate feasibility of isotropic 3-dimensional FSE shoulder imaging at 3-T magnetic resonance imaging (MRI). Methods Seventy-eight patients who underwent shoulder MRI were evaluated. Three-dimensional T2FS and 2D-PDFS were qualitatively graded for delineation of anatomic structures. In quantitative analysis, mean relative signal intensity and relative signal contrast between each structure of the shoulder were compared. Results Three-dimensional T2FS showed significantly higher scores for rotator cuff (P = 0.020), lower scores for bone (P < 0.001), and higher relative contrast of rotator cuff to fluid (P < 0.001) and labrum to fluid (P < 0.001) in comparison with 2D-PDFS. No significant difference in relative signal intensity of the rotator cuff, labrum, joint fluid, cartilage, and bone marrow was demonstrated. Conclusions Isotropic 3-dimensional FSE MRI has similar image quality and diagnostic performance to conventional 2-dimensional sequence in evaluation of the rotator cuff.
