| 中文摘要: |
| 目的 提高对强直性脊柱炎(AS) 患者骶髂关节炎的MR 早期影像特征的认识。方法 15 例AS 患者
MR 扫描序列包括SE T1WI、FSE T2WI 及梯度回波T2WI。结果 14 例AS 患者骶髂关节表现为T2WI 骨髓信号
不等程度增高,T1WI 及T2WI 示软骨信号增高或减低,形态不规则,部分呈碎裂状,T1WI 可清楚显示软骨增粗大于5mm 及破坏情况。结论 MRI 能观察到骨髓水肿、软骨的异常改变及骨髓内脂脉沉积,可作为AS 骶髂关节炎早期诊断方法。 |

| Purpose To evaluate the characteristic of early sacroilitis on MR imaging in patients with ankylosing
spondylitis (AS) . Method Fifteen AS patients were imaged with SE T1WI、FSE T2WI、T1 WI on MR examination. Results Of sacroiliac joints in fourteen patients were observed the cartilage abnormalities showed as irregular appearance ,
patchy distribution in some patients ,and higher or lower signal intensity on T1WI and T2WI. The cartilage signal became
thick and larger than 5mm ,and was showed erosion obviously on T1WI. The bone marrow was demonstrated by different
degree of higher signal intensity on T2WI. Conclusion MRI can reveal the bone marrow edema ,cartilage abnormalities and
fat accumulation in bone marrow and is helpful to the early diagnosis of sacroilitis in AS patients. |
