Before, During, and After: Your Complete MRI Test Timeline

If your doctor has just handed you a referral for an MRI scan, chances are you have a hundred questions swirling in your head. What exactly happens inside that machine? Will it hurt? How long does it take? What do you do once it’s over? You’re not alone, most people walking into an MRI suite for the first time feel a mix of anxiety and confusion simply because nobody ever walked them through the whole process.

This guide is here to change that. Before, During, and After: Your Complete MRI Test Timeline is exactly what it sounds like a plain-language walkthrough of everything you can expect from the moment you receive your MRI referral to the moment you get your results. No medical jargon, no vague reassurances. Just honest, practical information so you can show up prepared and leave feeling confident.

What Is an MRI and Why Does It Matter?

MRI stands for Magnetic Resonance Imaging. Unlike an X-ray or CT scan, an MRI uses powerful magnetic fields and radio waves, not radiation to produce detailed images of the soft tissues inside your body. This makes it especially valuable for examining the brain, spinal cord, joints, muscles, organs, and blood vessels.

Doctors order MRIs for a wide range of reasons: investigating unexplained pain, diagnosing neurological conditions, assessing sports injuries, monitoring tumours, or ruling out serious illness. Because the images are so detailed, an MRI often reveals what other scans simply cannot.

Understanding why you’re having the scan is the first step toward feeling less anxious about it.

BEFORE Your MRI: Everything You Need to Do in Advance

The Week Before Your Appointment

Once your MRI is scheduled, a little preparation goes a long way.

Review your medical history. Your diagnostic centre will likely send you a safety questionnaire. Fill it out honestly and thoroughly. This is not paperwork for the sake of paperwork — MRI machines use extremely strong magnets, and certain metal implants or devices in your body can be dangerous or can distort the scan images.

Common items you must disclose include:

• Pacemakers or implantable cardiac defibrillators
• Cochlear (hearing) implants
• Metal fragments from previous accidents or surgeries
• Aneurysm clips in the brain
• Insulin pumps or neurostimulators
• Any joint replacements or surgical screws

Most modern implants are MRI-compatible, but your radiologist needs to verify this beforehand. Never assume.

Check your medications. Most routine medications can be taken as normal before an MRI. However, if your scan requires sedation or contrast dye, you may be asked to adjust certain medications temporarily. Confirm this with your doctor or the diagnostic centre when you book.

Arrange transport if needed. If you’ll be receiving sedation or a contrast injection, it’s a good idea and sometimes a requirement to have someone drive you home. Sort this out in advance so it isn’t a last-minute scramble.

The Day Before Your MRI

The day before is mostly about keeping things simple.

Eat and drink normally unless you’ve been specifically instructed otherwise. For most standard MRIs, there are no dietary restrictions. If your scan involves abdominal imaging or contrast dye, you may be asked to fast for four to six hours beforehand — your diagnostic centre will tell you clearly if this applies to you.

Avoid heavy exercise. There is no strict medical rule against exercise the day before, but keeping your body relaxed and rested helps you lie still during the scan, which directly affects image quality.

Sleep well. Anxiety is completely normal before a medical procedure. A good night’s sleep won’t eliminate nerves, but it will help you manage them better when you’re in the scanning room.

The Morning of Your MRI

Dress appropriately. Wear loose, comfortable clothing with minimal metal — no underwire bras, belts with metal buckles, or clothing with zips or metal buttons if possible. You will likely be given a hospital gown to change into, but wearing simple clothing makes the process smoother and less uncomfortable.

Leave your jewellery at home. Rings, earrings, necklaces, piercings, and watches all need to come off before you enter the MRI room. Save yourself the hassle and leave them behind.

Bring your referral and any previous scans. Your radiologist will want to review prior imaging if available. Carry any relevant CDs, films, or printed reports from previous scans.

Arrive early. Aim to arrive at least 15 to 20 minutes before your scheduled time. You’ll need to complete or verify your safety questionnaire, change into a gown, and speak briefly with the MRI technologist.

Just Before You Enter the Scan Room

The MRI technologist — the trained professional who operates the scanner — will walk you through the procedure before it begins. This is your opportunity to ask any questions you still have. Good ones to ask:

• How long will this particular scan take?
• Will I be given contrast dye? If so, what should I expect?
• What should I do if I feel uncomfortable during the scan?

You’ll be asked to remove anything metallic from your body and your pockets. This includes hearing aids, glasses, hairpins, and even some makeup products that contain metallic particles. A secure locker will typically be provided for your belongings.

Tell the technologist if you’re claustrophobic. This is important. MRI machines are enclosed tubes, and the experience can feel overwhelming if you’re prone to anxiety in tight spaces. Diagnostic centres have ways to help — open MRI machines, mild sedation, or simply allow you to keep your eyes closed and play your music through headphones. There is no need to suffer in silence.

DURING Your MRI: What Actually Happens Inside the Machine

Positioning on the MRI Table

You’ll lie down on a padded, motorised table. The technologist will position you carefully depending on which part of your body is being scanned. If it’s a brain or head MRI, a special frame or coil will be placed around your head — this helps capture clearer images and does not touch or harm you in any way.

Pillows and foam pads may be used to keep you comfortable and correctly positioned. Earplugs or headphones will be offered because MRI machines are genuinely loud.

Entering the Scanner

The table will slide you into the MRI scanner. For most full-body scans, your entire upper or lower body will be inside the cylindrical tube. For limb scans — a knee or wrist, for example — only that body part enters the machine, which is far less claustrophobic.

The bore (the tunnel opening) of a standard MRI machine is roughly 60 to 70 centimetres in diameter. If you’re concerned about the size, ask your diagnostic centre whether they have a wide-bore or open MRI option.

The Sounds You Will Hear

This surprises many first-time patients. MRI machines are not quiet. You will hear a series of loud banging, knocking, clicking, and humming sounds throughout the scan. These are completely normal — they’re produced by the magnetic coils inside the machine as they activate and switch off.

The sounds change rhythm and intensity at different stages of the scan. They can be startling if you’re not expecting them. Knowing this in advance makes a significant difference.

Staying Still — The Most Important Thing You Can Do

Movement blurs MRI images in the same way movement blurs a photograph. The clearer you remain, the better the images, and the less likely you are to need the scan repeated. Breathe normally and steadily. Swallow when you need to, but try not to shift your body position.

For some scans — particularly lung or abdominal scans — you may be asked to hold your breath for short intervals of five to twenty seconds. The technologist will coach you through these moments clearly.

The Contrast Injection (If Applicable)

Some MRIs use a contrast agent — typically a gadolinium-based dye — which is injected into a vein in your arm. Contrast dye makes certain tissues and blood vessels appear much brighter on the scan, helping the radiologist identify abnormalities with greater accuracy.

The injection is given through a small cannula (a thin plastic tube). You may feel a brief cold sensation or mild warmth as the dye enters your bloodstream. Some people notice a metallic taste for a moment. These sensations are temporary and harmless.

Serious allergic reactions to MRI contrast dye are rare, but the team at your diagnostic centre is trained to handle them. If you have a history of allergies or kidney problems, always disclose this before your scan.

Communication During the Scan

You are never alone. The technologist monitors you through a window and via a camera throughout the procedure. You will be given a call button — a small rubber squeeze ball — to press if you feel unwell, anxious, or need the scan to stop.

There will also be an intercom, so you can speak to the technologist at any point and they can speak to you. Use it. There is no such thing as an unnecessary interruption.

How Long Does an MRI Take?

This varies considerably depending on the area being scanned and the complexity of the study:

• A brain MRI typically takes 30 to 45 minutes
• A spinal MRI can take 45 to 60 minutes
• A joint MRI (knee, shoulder) usually takes 30 to 40 minutes
• Abdominal or pelvic MRI may take 45 to 75 minutes
• Full-body or complex multi-region scans can exceed 90 minutes

If contrast is being used, additional time is added for the injection and a second round of imaging. Your diagnostic centre should give you a realistic time estimate when you book.

AFTER Your MRI: What Happens Once You’re Done

Immediately After the Scan

The table will slide out, and the technologist will help you off. That’s genuinely it — for most patients, there is nothing to feel or recover from. MRIs produce no radiation and have no known side effects.

If you did not receive sedation or contrast dye, you can drive yourself home, eat normally, and return to your regular routine immediately.

If you had contrast dye, drink plenty of water over the next few hours to help your kidneys flush it out naturally. Most people experience absolutely no side effects. A very small number may notice mild nausea, headache, or warmth at the injection site — these typically resolve within a few hours.

If you were sedated, you must not drive or operate machinery for at least 24 hours. Have your arranged companion take you home and rest for the remainder of the day.

Watch for Unusual Reactions

Though rare, it’s worth being aware of signs that warrant a call to your diagnostic centre or doctor:

• Hives, itching, or a rash following contrast dye
• Difficulty breathing
• Swelling around the eyes or throat
• Persistent headache or dizziness that doesn’t improve

These symptoms are uncommon but should be taken seriously.

Understanding Your MRI Report

Your scan images are analysed by a radiologist — a specialist doctor trained in reading medical imaging. They will prepare a written report describing their findings.

How long does it take to get results? This depends on your diagnostic centre and the urgency of your scan. Routine reports are typically ready within 24 to 72 hours. Urgent or complex cases may be prioritised and turned around faster.

At Al-Noor Diagnostic Centre, we ensure that your reports are prepared accurately and delivered promptly, with clear communication at every step.

How to Read (and Not Misread) Your Report

When your report arrives, resist the urge to Google every term you don’t understand. Radiology reports are written for doctors, not patients, and terms that sound alarming in isolation often mean something quite routine in context.

Instead, take your report to your referring doctor — the GP, orthopaedic surgeon, neurologist, or specialist who ordered the MRI in the first place. They will interpret the findings in relation to your symptoms, history, and overall health picture. The radiology report is one piece of the puzzle, not the entire picture.

Your doctor may:

• Confirm a diagnosis and recommend treatment
• Request a follow-up scan or additional tests
• Refer you to a specialist for further assessment
• Reassure you that nothing significant was found

Whatever the outcome, a clear, timely MRI report helps your medical team make better decisions for your health.

Following Up After Your MRI

Keep a copy of your MRI report and images (usually provided on a CD or available digitally). If you ever see a different doctor or need a second opinion, having your scan available saves time and avoids unnecessary repeat imaging.

If your doctor recommends a follow-up MRI in three months, six months, or a year, book it on time. Follow-up scans track changes over time and are often more informative than a single scan in isolation.

A Few Tips to Make Your MRI Experience Easier

Practice slow breathing. Deep, slow breaths calm the nervous system and make lying still much easier. If you know you’re anxious about medical procedures, practise the technique a few days before your appointment.

Try a mental distraction. Plan a podcast, audiobook, or playlist in your head. Some centres will play music through the headphones during your scan. Mentally going somewhere else — even just thinking through a recipe or replaying a happy memory — helps pass the time inside the scanner.

Ask for a blanket. MRI suites are often kept cool. There’s nothing wrong with asking for a blanket. Warmth helps you stay relaxed and still.

Communicate openly with your technologist. They perform MRI scans day in and day out. There is no question too basic, no concern too small. A good technologist will make your experience significantly more comfortable.
