Being told you need a scan can raise a lot of questions. What will it feel like? How should you prepare? When will you hear the results? Medical imaging is one of the most useful tools your care team has, and most tests are quick, painless and simple. Knowing what to expect can turn a worrying appointment into a calm and easy one.
Why your doctor orders imaging
Imaging lets your doctor look inside the body without surgery. An ultrasound uses sound waves to show soft tissues, organs and blood flow. An X-ray gives a clear view of bones and the chest. A CT or MRI scan builds detailed pictures that help explain symptoms such as ongoing pain, headaches or swelling. Your doctor chooses the test that answers your question in the safest, simplest way.
How to prepare
Some tests need no preparation at all, while others ask you to avoid food for a few hours, drink water beforehand or wear clothing without metal. Tell your care team if you are pregnant or might be, if you have a pacemaker or metal implant, or if you feel anxious in small spaces. Bring a list of your medicines and any earlier scan reports.
During and after the test
A technologist will explain each step and stay in contact with you throughout. You may need to lie still, change position or hold your breath briefly. Most people return to normal activities straight away. A specialist will review the images and send a report to your doctor, who will explain what the results mean for you and agree any next steps.
A scan is simply a way of looking more closely, so your care team can give you clearer answers.
Questions worth asking before your scan
Write these down and bring them to your appointment:
- Why is this test the right choice for me?
- Do I need to stop eating, drinking or taking any medicine?
- What should I wear and what should I leave at home?
- Will I need someone to drive me home?
- How and when will I hear about my results?
