AJR Expert Panel Review: MRI Reporting for Suspected and Established iNPH

Suspected idiopathic normal pressure hydrocephalus: AJR expert panel recommends unenhanced MRI with 3D T1-weighted sequence; report ventriculomegaly, high-convexity narrowed sulci, enlarged Sylvian fissures (disproportionately enlarged subarachnoid space hydrocephalus), and aque…

• The consensus statements summarize the unenhanced brain MRI protocol, including 3D T1-weighted imaging, and findings to report for both diagnosis and treatment monitoring.
• Imaging should not only support iNPH but also identify findings suggestive of alternate diagnoses or co-pathology.
• Incidentally detected findings supportive of iNPH can be reported in the impression with a hedge tied to the clinical context.
