PMS MRI what to expect

Overview

An MRI (magnetic resonance imaging) scan is a safe and painless test that uses a powerful magnet and radio waves to take detailed pictures of the inside of your body. It helps doctors see problems that other imaging tests might miss.

Yes. MRI scans are used every day in hospitals and imaging centers around the world to help diagnose and monitor many health conditions.

Anyone – children, adults, and older people – may need an MRI to help understand symptoms such as pain, injury, or abnormal findings in blood tests.

Symptoms

Common symptoms

• Loud tapping, clicking, or knocking noises from the scanner during the test.
• A feeling of warmth in the area being scanned, especially if contrast dye is used.
• Numbness or tingling if you have to stay very still for a long time.

Symptoms in children

• Children may feel anxious about lying still in the scanner or being alone in the room.
• Some children need a medicine to help them relax or sleep before the scan – the care team will discuss this if needed.

Symptoms in older adults

• Older adults may find it uncomfortable to lie flat for a long time due to joint stiffness or back pain.
• Cushions and padding can help make the scan more comfortable.

Causes

Main causes

• Your doctor has requested a detailed image of a specific part of your body, such as the brain, spine, joints, or abdomen.
• You have persistent pain, swelling, or unexplained symptoms that need further investigation.
• You are being monitored after a diagnosis or surgery to see how well treatment is working.

Risk factors

• Having a pacemaker, implanted device, or certain metal fragments in your body may require special checks or may make MRI unsafe.
• Severe kidney disease may affect your ability to receive contrast dye safely.
• Claustrophobia (fear of enclosed spaces) or anxiety can make the scan more challenging.

When to see a doctor

See a doctor urgently if:

• New or worsening pain, sudden weakness, or any concerning symptoms should be checked without delay.
• If you have a known allergy to contrast dye and you've just had an MRI with dye, call for medical advice immediately if you notice symptoms.

Book a routine appointment if:

• If your doctor has recommended an MRI, schedule it as soon as convenient – waiting is rarely needed.
• Make an appointment to review your MRI results with your doctor.

Diagnosis

An MRI is itself a diagnostic test. It produces detailed images that let your doctor see what may be causing your symptoms. For most MRI exams, no special preparation is needed.

Tests that may be done

• You will lie on a padded table that slides into the scanner – you may have an injection of contrast dye to make certain tissues stand out more clearly.
• The radiographer gives you earplugs or headphones to block the loud noise.
• After the scan, a radiologist reviews the images and sends a report to your doctor.

What to expect at your appointment

The scan usually lasts 30–60 minutes. Remove any jewellery, glasses, or clothing with metal, and you may be asked to change into a hospital gown. If contrast is used, it is given through a small tube in your arm. You will hear loud noises and must lie still. You can stop the scan at any time if you are uncomfortable.

Treatment

An MRI does not treat or cure anything – it gives your doctor the information needed to decide what treatments may help. The right treatment depends entirely on the underlying problem found.

Self-care at home

• After a standard MRI, you can usually return to normal activities immediately.
• Drink extra water if you had contrast dye to help your body remove it.
• If you felt anxious, relax afterwards – deep breathing or a short walk can help.

Medical treatments

Depending on the results, your doctor may recommend a range of treatments – for example, pain relief, antibiotics, physical therapy, or referral to a specialist. Always follow the treatment plan your healthcare team sets out for you.

When is surgery considered?

If the MRI shows a problem that may need surgery, your doctor will explain this and refer you to a surgeon. Surgery is only recommended when necessary and never as a first option without discussion.

Living with this condition

If you are waiting for an MRI or its results, try to keep your normal routine. A healthy sleep schedule, regular meals, and staying connected with friends and family can help reduce worry.

Lifestyle tips

• Continue your usual daily activities unless your doctor advises otherwise.
• Let the imaging team know if you have any health conditions or concerns before the scan.
• If you feel claustrophobic, ask about relaxation techniques, medication, or an open MRI option.

Diet and exercise

Most MRI scans do not require special foods or fasting. If your MRI needs you to fast, the hospital will tell you in advance. Regular exercise and a balanced diet support your overall wellbeing while you wait for results.

Mental health and emotional wellbeing

Waiting for answers about your health can be stressful and worrying. It is normal to feel anxious or down. Talk to a trusted friend or family member, and consider speaking with a counselor if the feelings become overwhelming.

Prevention

An MRI is not something that can be prevented – it is a diagnostic tool. The condition being investigated may be preventable in some cases, but many reasons for an MRI are unrelated to lifestyle.

Vaccines

Staying up to date with recommended vaccines can prevent some infections that might later require imaging to diagnose complications.

Screening programmes

MRI is sometimes used as a screening test for people at high risk of certain conditions, such as breast cancer. Ask your doctor whether you are eligible for any screening programs.

Complications

If left untreated

• If a serious condition goes undiagnosed, it may get worse over time.
• Postponing a required MRI could delay your treatment and affect your outlook.

Long-term outlook

Most MRI scans are completed without problems, and the results will give your doctor a much clearer picture of your health. Whatever the findings, understanding your body is the first step toward getting better – and there are many effective treatments available today.
