Normal Brain MRI Report Template (Without Contrast)
Normal non-contrast brain MRI report template: parenchyma by sequence, diffusion, susceptibility, ventricles and flow voids.
EXAMINATION: MRI brain without intravenous contrast. CLINICAL HISTORY: [indication] COMPARISON: None available. TECHNIQUE: Multiplanar, multisequence MR imaging of the brain without intravenous contrast, including diffusion-weighted and susceptibility-weighted sequences. FINDINGS: Parenchyma: Normal signal. No mass, edema or abnormal enhancement pattern on noncontrast sequences. Diffusion: No restricted diffusion to suggest acute infarct. Susceptibility: No hemorrhage or abnormal mineralization. Ventricles and sulci: Normal for age. No hydrocephalus. Midline: No shift. Posterior fossa: Unremarkable. Vascular flow voids: Preserved. Orbits, sinuses and mastoids: Grossly unremarkable. IMPRESSION: 1. Normal MRI of the brain.
Dictation notes
- “Normal for age” does real work on volume loss and white matter — anchor it to the stated age.
- Negative diffusion deserves its own line when the indication is stroke; it is the question being asked.
Frequently asked questions
What sections belong in a normal brain MRI report?
A structured brain MRI report addresses the parenchyma (signal, mass, edema), diffusion-weighted imaging for acute infarct, susceptibility-weighted imaging for hemorrhage or abnormal mineralization, ventricles and sulci relative to age, midline position, the posterior fossa, vascular flow voids, and the imaged orbits, sinuses and mastoids. The normal impression is 'Normal MRI of the brain.'
Why does a brain MRI report say 'normal for age'?
Ventricular size, sulcal prominence and scattered white matter signal change all shift with normal aging, so 'normal for age' anchors the assessment to the patient's stated age rather than to an idealized young brain. The phrase does real work: the same degree of volume loss can be normal at 80 and abnormal at 40. Without the age anchor, follow-up readers cannot tell deliberate judgment from oversight.
Should negative diffusion findings be stated when stroke is suspected?
Yes. When the indication is stroke or acute neurologic deficit, the absence of restricted diffusion deserves its own explicit line — it is the question the study was ordered to answer. DWI is the most sensitive sequence for acute infarction, positive within minutes of onset, so a specific statement such as 'no restricted diffusion to suggest acute infarct' answers the clinical question directly rather than leaving it implied by a generally normal report.
