PDFAbstract
Objective The purpose of the study was to evaluate the feasibility and application value of MR 3D T1-Weighted Gradient-Echo Imaging with a volumetric interpolated breath-hold examination (3D T1WI-VIBE) in the evaluation of joint cartilage of SIJ in patients with ankylosing spondylitis. Methods A total of 10 AS patients were collected randomly and the 3D T1-VIBE were performed for sacroiliac joint. MR manifestation of sacroiliac articular cartilage of 10 cases of ankylosing spondylitis patients were observed. Results 3D T1-VIBE sequence were performed in 10 patients (20 SIJs) with ankylosing spondylitis, blur iliac side edge of articular cartilage were showed in 3 cases. The gap between cartilage in the sacral and iliac side become unclear and even disappear, seven of ten articular cartilage shown erosion damage, discontinuous change. Conclusions 3D T1-VIBE can show the destroy and break of the articular cartilage in patients of AS. 3D T1-VIBE is a valuable technique for examination of articular cartilage of SIJ, which provides more information for clinic than X-ray and CT.
