Averaged time-courses for the segmented brain demonstrate a larger peak-to-trough in gray matter compared to white matter (A). Averaged time-courses demonstrated a smaller peak-to-trough in brain tumors than normal tissue with the peak occurring slightly later in tumors. When the time-courses were separated by tumor grade, the normal side tissue shows the expected shape from the BH paradigm performed (C), however, the tumor side tissue lacks the expected shape, and exhibits a noisier time course (D).
