If you have a scan scheduled soon, good preparation can make everything easier and more comfortable. Taking a few simple steps before your diagnostic scan helps you feel calm, avoid mistakes, and get accurate results. This guide will show you what to do before, during, and after your scan so you can walk into the imaging room with full confidence.
Why Proper Preparation Is Important for Scans
Accuracy of results depends on your readiness
Even a small mistake, such as eating before a fasting test or wearing metal, can affect scan results. Preparing correctly ensures that doctors receive clear and accurate images of your body.
Reducing stress and avoiding delays
Knowing what to expect helps reduce anxiety. When you arrive prepared, the process becomes smoother, and your appointment stays on time.
Ensuring safety during the procedure
Some scans use contrast dye or magnets. Proper preparation helps protect patients with allergies, pacemakers, or other implants. Informing the staff about your medical history helps avoid any risks.
What to Do Before Your Appointment
A few small steps before your scan can save time and help doctors get the most accurate results from your test.
Check your booking details and location
Confirm your appointment date, time, and location. Make sure you know how long the scan will take and whether you need to fast.
Understand the type of scan you are having
Different scans have different rules. An MRI, CT, ultrasound, or X-Ray each requires separate preparation. Ask your doctor or the imaging center for clear instructions.
Make a list of medications and allergies
Write down all medicines you take, including vitamins and herbal products. Inform your technician if you have any allergies, metal implants, or medical devices.
Preparing the Night Before and on the Day of the Scan
What you do the night before and on the scan day directly affects your comfort and the accuracy of the results.
Fasting and hydration rules
Some scans, such as those using contrast dye, require fasting for 6 to 8 hours. Others may ask you to drink water before the procedure. Always follow the exact instructions given by the center.
Clothing, jewelry, and metal removal
Wear loose and comfortable clothes without zippers or buttons. Remove watches, belts, and jewelry before the scan to prevent interference.
Arrival time and documents
Arrive 15 to 30 minutes early to complete the forms. Bring your ID card, doctor’s referral, and any previous reports or films for comparison.
What Happens During the Scan
Knowing what happens inside the scanning room helps you stay relaxed, follow instructions, and complete the test with confidence.
What happens inside the machine
You will be asked to lie on a soft table that moves slowly inside the scanner. The machine takes pictures of your body using magnetic or radiation waves.
Staying still and following instructions
Movement can blur images, so remain as still as possible. Listen to the technician’s instructions carefully to ensure clear results.
Communicating anxiety or discomfort
If you feel nervous, tell the staff. They can help you stay calm or give ear protection for loud noises in an MRI. Most centers allow you to communicate through a microphone during the scan.
What to Expect After the Scan
Once your scan is done, a few simple follow-up steps help you understand your reports and plan your next actions.
Receiving your reports and images
Reports are usually available on the same day or within 24 hours. You can collect them or receive them through email depending on the clinic’s policy.
How to follow up with your doctor
Share your results with your doctor for further analysis. If something unusual appears, your doctor may ask for a repeat scan or additional tests.
When to ask for second opinions
If you are unsure about your results, it is fine to seek another doctor’s opinion. It helps you understand the findings clearly and make informed decisions.
Frequently Asked Questions
How long before the scan should I fast
Most centers ask for fasting 6 to 8 hours before certain scans, especially those using contrast materials. Always check the instructions before your visit.
Can I take medications before my scan

What if I am claustrophobic or anxious during MRI
Inform the technician before the scan. They can play calming music or offer mild sedation if required.
