T1 relaxation time sufficient to produce pallidal T1 hyperintensity in hepatolenticular degeneration. [4] Manganese is also used as MR contrast due to the above properties but surprisingly SWI failed to show any blooming. Interestingly, calcification containing diamagnetic calcium is visualized in SWI and hence is used in the seizure MR imaging protocol.[5] The magnetic susceptibility of parama...
