What to Expect at Your MRI Scanner Appointment

Introduction

An MRI (Magnetic Resonance Imaging) scan is a non-invasive medical test that helps doctors diagnose and treat medical conditions. It uses strong magnetic fields and radio waves to produce detailed images of the inside of your body. Understanding what to expect during your MRI scanner appointment can help alleviate any anxiety or concerns you may have. This guide provides a walkthrough of the procedure, specifically for patients in the United Kingdom.

Before the Scan

Before undergoing an MRI scan, you will likely be asked to complete a questionnaire about your medical history and any metal implants in your body, such as pacemakers or joint replacements. It is important to mention any metal items since the strong magnetic fields used in the scan can interfere with them. You may also be advised to remove all metal objects, including jewelry, glasses, and hearing aids, before the scan.

Arrival and Preparation

When you arrive at the MRI facility, you will be greeted by the radiography team. You'll be directed to a waiting area and, when it's time for your scan, taken to a changing room. Here, you may be asked to change into a hospital gown to ensure no metal objects interfere with the imaging process.

During the Scan

Once you are prepared, you will be taken to the MRI scanner room, which contains a large, cylindrical machine. You will be asked to lie down on a movable table that slides into the scanner. It's crucial to remain very still during the scan to ensure the images are as clear as possible. You will be provided with ear protection or headphones, as the MRI machine makes loud tapping and banging noises during operation.

Communication and Comfort

The radiographer will be able to communicate with you throughout the scan via an intercom system. You can signal if you feel uncomfortable or need assistance at any point. Though the scanner can feel a little confined, there is adequate ventilation, and some newer machines even offer more space inside the bore.

After the Scan

The MRI scan typically takes 15 to 90 minutes, depending on the type of imaging required. Once the scan is completed, you can change back into your clothes. There are no known side effects from an MRI scan, and you can generally resume normal activities immediately afterwards. Your results will be analyzed by a radiologist and sent to your referring doctor, who will discuss them with you during a follow-up appointment.

Conclusion

An MRI scan is a safe and important diagnostic tool. Knowing what to expect can make the process smoother and more comfortable. Always follow any specific instructions provided by your healthcare provider, and don't hesitate to ask questions. Your comfort and understanding are crucial for obtaining the best possible imaging results.
