MRA (magnetic resonance angiography) and MRV (magnetic resonance venography) are MRI-based scans that visualize arteries and veins, respectively. They produce detailed, noninvasive images to detect aneurysms, stenosis, vascular malformations, or clots. Techniques may use contrast (gadolinium) or special sequences. They avoid ionizing radiation but can be unsuitable with certain implants or severe kidney dysfunction due to contrast risks.

An MRA of the spine is a magnetic resonance angiography scan that noninvasively images the spinal blood vessels and blood flow. It detects vascular problems affecting the spinal cord—such as arteriovenous malformations, fistulas, stenosis, aneurysms or tumor-related blood supply—and helps guide treatment. It typically uses MRI techniques with or without gadolinium; some implants and severe kidney disease are contraindications.

Before an MRV, wear loose, metal-free clothing and remove jewelry, watches, and piercings. Tell staff about implants, pacemakers, pregnancy, allergies, or kidney problems—contrast (gadolinium) may require a recent kidney function test. You usually don’t need to fast or stop meds unless instructed. Bring prior imaging and arrive early. Expect to lie still; discuss sedation if you’re claustrophobic.

In Chennai, an MRI brain with MRA and MRV typically costs approximately INR 6,000–18,000 (about USD 75–225). Prices vary by facility, machine strength (1.5T vs 3T), use of contrast, center reputation, and whether additional radiologist fees or urgent scheduling apply. Always confirm the final price and included services with the imaging center before booking.

Magnetic resonance venography (MRV) is generally safe, but risks include problems from MRI itself (claustrophobia, loud noise, and incompatibility with some metal implants or pacemakers) and from contrast dye (rare allergic reaction, injection-site pain, and in people with severe kidney disease a small risk of nephrogenic systemic fibrosis; possible gadolinium retention). Sedation risks and very rare infection or bleeding at the injection site may occur.

Cost of an MRA varies widely by country and provider. In the UK it's usually free on the NHS; in India private centers often charge roughly ₹2,000–15,000. In the US typical billed prices range from several hundred to several thousand dollars; insured patients usually pay a reduced copay or coinsurance. Final cost depends on facility, use of contrast, and whether outpatient, hospital, or emergency setting.
