Abstract
We present a new steady-state imaging sequence, which simultaneously allows in a single acquisition the formation of two MR images with clearly different contrasts. The contrast of the first image is FISP-like, whereas the second image is strongly T2-weighted. In principle the T2 values in the image can be calculated from the combination of the first and second images. We also show calculated T2 images.
摘要
我们提出了一种新的稳态成像序列，该序列能够在一次采集中同时生成两幅具有明显不同对比度的磁共振图像。第一幅图像的对比度类似快速成像稳态进动（FISP），而第二幅图像则具有很强的T2加权。原则上，图像中的T2值可以通过第一幅和第二幅图像的组合来计算。我们还展示了计算得到的T2图像。
