MRI for vertigo targets the posterior fossa, brainstem, cerebellum and internal auditory canals. Protocol typically includes high-resolution 3D T2 (CISS/FIESTA) for inner ear/IAC, axial and coronal T2/FLAIR, diffusion-weighted imaging for acute stroke, susceptibility/SWI for hemorrhage, and pre- and post-contrast T1 with fat-saturation to assess enhancement. Thin slices (≤1 mm) and MR angiography may be added if vascular causes are suspected.

For vertigo, an MRI of the brain focused on the posterior fossa and internal auditory canals is preferred. Contrast-enhanced MRI (gadolinium) is used when inner‑ear tumors or inflammatory lesions are suspected. Diffusion‑weighted MRI helps rule out acute stroke, and MR angiography may be added if a vascular cause is suspected. Clinical findings guide the exact MRI protocol.

A neurologist evaluates vertigo with a detailed history and neurological exam, observing eye movements and gait. Bedside tests include Dix–Hallpike and head‑impulse testing, HINTS (head impulse, nystagmus, skew) to distinguish peripheral from central causes, and Romberg. Hearing assessment and vestibular function tests (VNG/ENG) may follow; MRI or CT is used if central pathology is suspected.

Brain MRI does not usually cause vertigo, but some people experience transient dizziness. Causes include lying still, anxiety or claustrophobia, rapid standing after the scan, or rare magnetic vestibular stimulation from strong MRI fields, which can produce brief imbalance or nystagmus. Symptoms are typically short‑lived; seek medical advice if vertigo is severe, persistent, or accompanied by other neurological signs.

Brain-related (central) vertigo signs include sudden severe imbalance with difficulty walking, persistent vertigo without hearing loss, vertical or direction-changing nystagmus, and accompanying neurological symptoms such as double vision, slurred speech, facial numbness/weakness, difficulty swallowing, severe headache, or reduced consciousness. Symptoms that don’t improve with positional maneuvers or occur in people with vascular risk factors warrant urgent medical evaluation.

An MRI brain protocol typically includes patient screening and positioning in a head coil, non-contrast sequences (axial T1, T2, FLAIR), diffusion-weighted imaging (DWI/ADC), susceptibility-weighted or gradient-echo, and optional contrast-enhanced T1 with fat suppression. Parameters use thin slices (3–5 mm), multiplanar acquisitions, and motion-reduction measures. Contrast is indicated for suspected infection, tumour, inflammation, or blood–brain barrier disruption.
