[Abstract] Objective: To compare three-dimensional double-echo steady state (3D-DESS) and three-dimensional perfection with application optimized contrasts using different flip angle evolutions (3D-SPACE) in the evaluation of sacral plexus (SP).Materials and Methods: Ten volunteers underwent 3D-DESS and 3D-SPACE using a 3.0 T MRI scanner. Ninety-eight consecutive patients with suspected SP disease underwent 3D-DESS and 3D-SPACE at a 3.0 T MRI. The scores and details SP in 3D-DESS and 3D-SPACE had been prospectively interpreted by 2 radiologists Standardized "Likert" scales from 1 to 5 were used to evaluate the imaging qualities; the length of L5 and size of L5 ganglions in 3D-DESS and 3D-SPACE were applied using comparative t-test to perform statistical analysis. Comparisons between normal and abnormal anatomy in SP were evaluated using the Mann-Whitney U test.Results: 3D-SPACE was significantly superior to 3D-DESS (t=9.481, t=5.45, P=0.000) in the evaluation of SP nerve fibers. There was no significance in L5 ganglions size (P=0.79, P=0.70 respectively) between 3D-DESS and 3D-SPAC; 3D-SPACE (4.41±0.67) was significantly superior to 3D-DESS (3.75±0.75) in normal anatomy structures (U=38, P=0.036). 3D-DESS (4.07±0.83) was superior to 3D-SPACE (3.57±0.65) in evaluating the detailed pathological structures, however, there was no significant differences (U=65, P=0.099).Conclusion: 3D-DESS is significantly superior to 3D-SPACE in the evaluation of the detail of SP. Combined 3D-DESS and 3D-SPACE provide a noninvasive tool in the evaluation of SP.
