shiny corners啥意思？

IMAGING STUDIES 

• Classic feature is bilateral sacroiliitis on pelvic radiographs (modified NY criteria). 

• Vertebral bodies lose anterior concave shape and become square. 

• With progression, calcification of the annulus fibrosus and paravertebral ligaments develops, giving rise to the so-called bamboo spine. (Figs. E2 through E6). 

• Severe diskovertebral erosions and destruction may occur (Andersson lesion, Fig. 7). 

• MRI (Fig. E8) may be useful in detecting early inflammatory lesions and is especially helpful when the history is suggestive but radiographs are equivocal; can see bone marrow edema, fatty metaplasia, sacroiliitis, erosions, shiny corners.

影像学检查

l 典型的特征是骨盆X线片上的双侧骶髂关节炎(修订的NY标准)。

l 椎体失去前凹的形状，方形变。

l 随着病变的进展，椎间盘的纤维环和椎旁韧带钙化，形成所谓的“竹节样脊柱”。(图E2～E6)。

l 可能出现严重的椎间盘侵蚀和破坏(Andersson病变，图7)。

MRI(图E8)可能有助于发现早期炎性病变，尤其是当病史提示但X线片不明确时，尤其有用，可以看到骨髓水肿、脂肪化生、骶髂关节炎、糜烂、发亮的角落。
