Comparative Analysis of Computed Tomography and Magnetic Resonance Imaging in Clinically Examining Sacroiliac Joint Complications of Ankylosing Spondylitis

Background: To analyze computed tomography (CT) and magnetic resonance Imaging (MRI) in examination diagnosis of sacroiliac joint disease of ankylosing spondylitis. Methods: Eighty patients with ankylosing spondylitis were randomly selected our experimental subjects, and CT and MRI examinations were performed on them to observe and analyze the diagnosis results of the two examination methods. Results: The detection rates of I and II for ankylosing spondylitis sacroiliac joint disease were prominently higher than those of CT (P <0.05). Note that detection rates pertaining to MRI on ankylosing spondylitis, sacroiliac joint disease, erosion of the articular surface, and bone cysts under the articular surface were significantly higher than those of CT (P < 0.05). There exists no significant differences in the detection rates of widening or narrowing and joint ankylosis (P > 0.05). Conclusions: The detection rate of MRI in clinical diagnosis of sacroiliac joint disease of ankylosing spondylitis is higher than that of CT. It possesses excellent clinical promotion and application.
