Abstract
We reviewed magnetic resonance images (MRIs) of 91 patients to estimate the chronologic age of closure of the neurocentral cartilage in the thoracic spine. The neurocentral cartilage on MRI appeared low signal in both T1- and T2-weighted images. It was thick and clearly identified in younger patients but was thin and vague in older patients. The neurocentral cartilage closed at 11-16 years in female patients and at 12-16 years in male patients.
摘要
我们回顾了91例患者的磁共振成像（MRI），以估计胸椎神经中央软骨闭合的时间年龄。MRI上的神经中央软骨在T1加权和T2加权图像上均呈低信号。它在年轻患者中较厚且清晰可辨，但在老年患者中较薄且模糊。女性患者的神经中央软骨在11至16岁时闭合，男性患者在12至16岁时闭合。
