Gradient echo signal and contrast calculator

November 24, 2018

First choose tissue T1 and T2 values.Then select your scanning TR, TE  and flip angle. You can also set a field inhomogeneity factor. The calculator uses an estimated value of T2* based upon this and the tissue T2.The graph shows the signal intensity (max = 1) for both tissues, the contrast and the relative contrast … More Gradient echo signal and contrast calculator
