In this case, the very high signal in both lesions on the T1-weightedimages suggests fat content.
在本例,两者在T1序列上显示高信号提示脂性成分。

On MRI, the tumor showed a slightly low signal on T1-weightedimages, a high signal on T2-weighted images, and poor enhancement after gadolinium injection.
Figure 3, Figure 4, and Figure 5: Axial, coronal, and sagittal T1-weightedimages with contrast demonstrate heterogeneous enhancement of the lesion (yellow arrows).
