wart MRI what to expect
Informed by recognized medical guidance
Overview
An MRI (magnetic resonance imaging) is a scan that uses strong magnets to take detailed pictures of the inside of your body. For a wart, an MRI is sometimes used to look more closely at a skin growth to make sure it is harmless and only on the surface.
Key facts
- An MRI does not use radiation.
- You lie still on a table that slides into the scanner.
- The scan is painless, but the machine makes loud knocking noises.
MRIs for warts are uncommon. Most warts can be diagnosed simply by looking at them, so an MRI is only used in specific cases when a doctor needs more information.
Anyone can have a wart that needs further imaging, but an MRI is more likely to be considered if the growth is deep, painful, unusual in appearance, or in a place that is hard to examine.
Symptoms
- Severe bleeding from a skin growth that does not stop with direct pressure
- Signs of a severe allergic reaction if you have an MRI with contrast dye, such as trouble breathing, swelling of the face or throat, or sudden difficulty speaking
- ⚠A skin growth that changes rapidly over a few weeks
- ⚠A growth that becomes infected, with signs of warmth, redness, pus, or increasing pain
Common symptoms
- A small, rough bump on the skin with a cauliflower-like surface
- Pain or discomfort when pressing on the growth
- A growth that changes shape, color, or size over time
Symptoms in children
- A wart on the sole of the foot that causes discomfort when walking
- A wart that grows quickly or spreads to other areas
- A wart that bleeds after minor friction or injury
Symptoms in older adults
- A new growth that looks like a wart but feels firm or hard
- A wart that bleeds easily or does not heal
- A growth that appears in an area of skin that gets irritated frequently
Causes
Main causes
- Warts are caused by certain strains of the human papillomavirus (HPV), which enter the skin through tiny cuts or breaks.
- An MRI may be ordered when a doctor wants to check how deep a growth extends or whether it is affecting nearby structures.
Risk factors
- Having a weakened immune system, such as from an illness or certain medications
- Walking barefoot on warm, moist surfaces like public showers or pool areas
- Touching or scratching warts on another person or on yourself
- Having broken or irritated skin
When to see a doctor
See a doctor urgently if:
- If you notice a new growth that is growing quickly, changing color, or becoming painful, see a doctor within a few days.
Book a routine appointment if:
- If you have a wart that does not go away after a few months of home care.
- If you are unsure whether a growth is actually a wart or something else.
- If you have multiple warts that keep coming back.
Diagnosis
A doctor can usually tell if a growth is a wart by looking at it during a physical exam. An MRI may be suggested if the growth is deep, painful, or located in an unusual place where the doctor needs to see more detail.
Tests that may be done
- Physical examination of the skin growth
- Dermatoscopy, which uses a special magnifying lens to look at the surface closely
- MRI scan, if the doctor needs clearer pictures of the deeper soft tissues
What to expect at your appointment
If you have an MRI, you will be asked to lie on a narrow table that slides into the scanner. You will need to stay still during the scan, which usually takes 15 to 60 minutes. The machine is loud, but you will be given ear protection. You can talk to the technician through a speaker if you feel uncomfortable.
Treatment
Most warts do not need treatment and will clear up on their own. If a wart causes pain, spreads, or you simply want it removed, there are several safe options your doctor can discuss with you.
Self-care at home
- Keep the area clean and dry.
- Avoid picking, scratching, or trying to cut off the wart yourself.
- If the wart is on your foot, wear comfortable shoes and a soft pad to reduce pressure.
- Wash your hands well after touching the wart.
Medical treatments
Doctors can treat warts with a variety of methods, including freezing the wart with a cold spray, burning it with a small electric current, using a laser, or prescribing a topical cream to apply at home. The choice of treatment depends on the type, size, and location of the wart, as well as your health and preferences.
When is surgery considered?
Surgery is rarely needed for a wart. It may be considered if the wart is very large, painful, or has not responded to other treatments.
Living with this condition
For most people, a wart is a minor issue that does not stop them from doing normal activities. You can continue work, school, sports, and social life as usual while you wait for it to go away.
Lifestyle tips
- Wear flip-flops or shower shoes in public pools, locker rooms, and shared showers.
- Do not share towels, razors, socks, or shoes with others.
- Keep your hands clean and dry to lower the chance of spreading the virus.
Diet and exercise
Eating a balanced diet rich in fruits, vegetables, and whole grains supports a healthy immune system, which helps your body fight off the virus that causes warts. Regular exercise also supports overall health and immunity.
Mental health and emotional wellbeing
If a wart is visible or causes worry, it can sometimes affect your confidence or make you feel self-conscious. Talk to someone you trust about how you feel, and remember that warts are very common and nothing to be ashamed of.
Prevention
You can reduce your risk of getting warts by avoiding direct contact with warts on other people, keeping your skin healthy and intact, and practicing good hygiene, especially in public areas.
Vaccines
There are vaccines that protect against the most common strains of HPV that cause warts, but these are mainly given to children and young adults before they are exposed to the virus. Ask your healthcare provider whether the HPV vaccine is suitable for you or your child.
Screening programmes
There is no routine screening test for skin warts. You can check your own skin regularly and mention any new or changing growths to your doctor.
Complications
If left untreated
- Most warts will go away on their own without any treatment.
- In rare cases, a wart may bleed, become infected, or spread to other areas of the body.
- A persistent wart on the sole of the foot can make walking uncomfortable.
Long-term outlook
Warts are very common and usually harmless. Even if your doctor recommends an MRI, the scan is a simple and painless step that can give valuable information to make sure your health is on the right track. With time and proper care, warts often resolve completely.
