Example of bi-component T₂* analysis of a 23-year-old healthy volunteer. a R² map for bi-exponential T₂* calculation; b R² map for mono-exponential T₂* calculation; c mono-exponentially calculated T₂*; d short component of T₂* map; e long component of T₂* map; f the binary map of mono- and- bi-exponential pixels used for B/M ratio calculation. Individual maps are overlaid on vTE images, calculated as a subtraction of the shortest TE (0.8 ms) and the longest TE (20 ms). Note the higher R² values for bi-exponential calculation
