PDFAbstract
Objective To compare the clinical value of CT and MRI plain scan in detection of abnormal sacroiliac joint changes in patients with ankylosing spondylitis(AS). Methods The CT and MRI data of 60 cases of AS which undergoing treatment in the past three years were analyzed and compared retrospectively. Results The diagnostic effect of MRI for the early stage of AS is higher than that of CT, P＜0.05. The diagnostic effect of MRI and CT had no obvious difference in grade 2 or more serious cases, (P＞0.05). The detection effect of CT is higher than MRI in cases with bone erosion and bone hardening,P＜0.05. Conclusion The diagnostic effect of MRI is higher than that of CT in early stage of ankylosing spondylitis, CT is more sensitive in detecting bone erosion and bone hardening than MRI. The combination of CT and MRI in abnormal sacroiliac joint changes in patients with AS is of great significance.
