A magnetic resonance angiography (MRA) of the head and neck is a noninvasive MRI technique that produces detailed images of the blood vessels supplying the brain and neck. It detects aneurysms, stenosis, dissections, and vascular malformations and helps evaluate stroke risk. MRA can be done with or without gadolinium contrast, involves no ionizing radiation, and usually takes about 15–45 minutes.

Magnetic resonance angiography (MRA) images the brain’s blood vessels and blood flow. It shows arterial and venous anatomy, detects narrowing (stenosis), blockages or occlusions, aneurysms, dissections, and arteriovenous malformations. MRA helps evaluate stroke risk, vessel patency after treatment, and vascular causes of headaches or neurological symptoms. It is noninvasive and can be performed with or without contrast.

Magnetic Resonance Angiography (MRA) brain scan costs vary widely by country and facility. Typical private prices: United States about $400–$3,000; United Kingdom £250–£700 (NHS scans are free when clinically referred); India roughly ₹3,000–₹15,000; Australia about AUD 300–900. Use of contrast, higher‑field scanners and urgent/private appointments raise the price; check local imaging centers for exact fees.

A head MRI images brain structure and soft tissues to detect tumors, stroke, inflammation, or degenerative changes. An MRA (magnetic resonance angiography) is a specialized MRI technique that visualizes cerebral blood vessels and blood flow to identify aneurysms, stenosis, or vascular malformations. MRA often uses specific pulse sequences and sometimes contrast; it complements, rather than replaces, a standard brain MRI.

An MRA of the head and neck typically takes about 30–60 minutes for the imaging alone. Including registration, positioning, contrast injection if needed, and brief post-scan checks, plan for roughly 45–90 minutes at the imaging centre. Shorter non‑contrast or focused scans can be around 20–30 minutes, while more complex or combined studies may take longer.

A doctor orders a head MRA to noninvasively visualise brain blood vessels and detect problems such as aneurysms, arteriovenous malformations, stenosis or occlusion from atherosclerosis, and vascular causes of stroke or transient ischaemic attack. It’s used after unexplained sudden headaches, dizziness, trauma, or to plan or follow up vascular surgery/interventions and to assess blood flow when vascular disease is suspected.
