MR signal and contrast calculator (SE) The MR signal and contrast calculator or app lets you choose two tissue T1 and T2 whilst manipulating the scanner parameters: TR and TE to show the signal, contrast and relative contrast to noise ratio (CNR). Use the calculator to explore the weightings below. MR gradient echo signal and … More MR signal and contrast calculators
Gradient echo (GE, GRE, FLASH, SPGR, T1-FFE, FE) is one of the hardest elements of MRI to understand. Image signal and contrast in spoiled gradient echo depends upon three user-selected parameters: For any given tissue T1 and scanner TR there is a flip angle, the Ernst angle, that gives the maximum signal for that tissue. … More Gradient echo signal and contrast
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
