We characterize the contrast behavior of substantia nigra (SN) in both magnetization transfer (MT) imaging, which is believed to be sensitive to neuromelanin (NM), and susceptibility weighted imaging (SWI). Images were acquired with a MT prepared dual echo gradient echo sequence. The first echo was taken as the MT contrast image and the second was used to(More)

ER content of the rabbit uterus powder was determined using the conventional methods, i.e., Scatchard plot and sucrose density gradient methods. The rabbit uterus cytosol was serially diluted to give a(More)
