磁振造影检查，这类肿瘤在T1影像是呈现低讯号强度，T2影像是呈现稍微高讯号强度，打过显影剂以后肿瘤只呈现轻微的显影。
On MRI, the tumor showed a slightly low signal on T1-weighted images, a high signal on T2-weighted images, and poor enhancement after gadolinium injection.
磁振造影可应用于检查所有组织，其检查过程为非侵入性，没有副作用又无游离性放射线暴露，所以被普遍的使用。
MRI can be used in all kinds of tissue. Because the process is non-invasive and free of ionization radiation, it has been widely used.
