MRI

[Location] MRI may be helpful in the diagnosis of [disease name]. Findings on MRI suggestive of/diagnostic of [disease name] include:Jacob S, Gupta H, Nikolic D, Gundogdu B, Ong S (2014).

• Symmetric signal intensity abnormality in the central pons at T2-weighted and FLAIR imaging
  • This may progress to classic hyperintense “trident-shaped” central pontine abnormality, with sparing of the ventrolateral pons and corticospinal tracts
• Decreased T1 signal intensity
• Fluid attenuated inversion recovery (FLAIR) hyperintense lesion in the pons
• Intramedullary central T2 hyperintensity at axial T2W of spinal cord and sagittal T2W of thoracic spinal cord
