Wide Variation in Spine MRI Protocols for Spontaneous Intracranial Hypotension

Spine MRI protocols for spontaneous intracranial hypotension (SIH) show substantial heterogeneity in fat-suppression and echo time despite universal 3D T2-weighted imaging use across 9 US expert centers. Ambiguous terminology like 'MR myelography' complicates comparisons.

• Nine specialized US centers participated; all used 3D T2-weighted imaging.
• Inconsistent use of 'MR myelography' obscures whether the exam is non-contrast heavily T2-weighted MRI or intrathecal contrast-enhanced.
