In an ex vivo experiment of rat, FA map, with low values, failed to
detect crossing fibers (a). AKC identified the crossing fibers with elevated values
[(b), arrows]. Q-ball image (c), with the enlarged part (d), demonstrated
fibers cross in that region. BLFB staining image (e) coincided with AKC, fibers of axon
along the lesion boundary were evident in the magnification panel (f)
