Incontinentia pigmenti with sensorimotor polyneuropathy: a novel association.

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 paramagnetic manganese is much higher than diamagnetic calcium.[6] The association of manganese deposition and T1 hyperintensity is well known but the causation is not well established.
