  • * Printed films contain 20 images each.

  • The whole cerebrum, including the cerebellum and brainstem, should be included.

  • Reconstruction of 20 slices at 5 mm thickness in the bicallosal plane, centred on the basal ganglia.

  • 3D, three-dimensional; FGE, fast gradient echo; FOV, field of view; FSE, fast spin echo; IR, inversion recovery; NNIPPS, Neuroprotection and Natural History in Parkinson's Plus Syndromes; TE, echo time; TR, repetition time.
