We found that a magnetization transfer contrast (MTC) short echo scan, with a flip angle of 25-30o and a resolution of 0.67 x 0.67 x 1.34mm3 provides the best visualization of the LC.
Figure 2. The plot is shown for one slice that visualizes the
LC clearly. When we choose the upper region as reference, the contrast peaks at 25o with a resolution of 0.67×0.67×1.34mm3.
As for the lower region, the peak occurs at 30owith the same resolution. LR (0.67×1.34×2mm3)；HR1 (0.67×0.67×2mm3); and HR2 (0.67×0.67×1.34mm3).
Figure 1.
The two “frog eyes” represent the high signal of the LC. Once we choose the proper imaging parameters,
those little eyes light up. [The frog picture cited from Britannica Insights/7
