The low signal on T1 WI was still low signal intensity on T2 WI which suggested calcification.
T1加权像低信号区在T2加权像上随回波时间延长信号仍呈低信号而提示钙化。
Results. All the insufficiency fractures and metastasis at the sacrum revealed low signal intensity on T1-weighted MRI; low or high signal intensity was revealed on T2-weighted MRI.
结果： 在T1像上，所有的应力性骨折与转移瘤都表现为信号减低，而在T2加权像上则表现为低或高信号。
On MR images, the necrotic center of the nodes will show intermediate signal intensity on T1-weighted images, low signal intensity on T2-weighted images, and will enhance with contrast.
MR 影像上，在T1序列上中央坏死显示中度强度的信号，T2序列上呈低信号，增强扫描有强化。
