CTV Head There is no relevant literature to support the use of CTV head in the initial evaluation of a child with chronic nonprogressive ataxia. MRI Head MRI is the most widely utilized imaging method to evaluate chronic nonprogressive ataxia [4,32]. In a child with chronic nonprogressive ataxia, MRI is useful in identifying cerebellar and brainstem malformations to aid diagnosis. Imaging can be particularly useful in the diagnosis of certain syndromic causes of chronic nonprogressive ataxia such as rhombencephalosynapsis, Dandy-Walker or Joubert syndrome, and related disorders that have characteristic imaging findings [50]. Diffusion tensor imaging can facilitate assessment of white matter tract structure in congenital brainstem and cerebellar anomalies [4,6,43,52]. For example, absence of decussation of the superior cerebellar peduncles in Joubert syndrome and abnormal dorsal pontine transverse white matter bundles in pontine tegmental cap dysplasia are seen on diffusion tensor imaging [4]. There is no literature to support the use of IV contrast in this setting. MRI Complete Spine Because some congenital brainstem and cerebellar anomalies that present with chronic nonprogressive ataxia are associated with spinal anomalies, MRI of the complete spine may be helpful in individual cases [44]. There is no literature to support the use of contrast-enhanced imaging of the spine in this scenario. MR Spectroscopy Head There is no relevant literature to support the use of MR spectroscopy head in the initial evaluation of a child with chronic nonprogressive ataxia. MRA Head and Neck There is no relevant literature to support the use of MRA head and neck in the initial evaluation of a child with chronic nonprogressive ataxia. MRA Head There is no relevant literature to support the use of MRA head in the initial evaluation of a child with chronic nonprogressive ataxia.
