The Procedure of an Abdomen MRI

Understanding the technical aspects of an abdomen MRI involves knowing the procedure and the preparations required. This knowledge includes your dietary guidelines, dress code, and the use of contrast agents during the procedure. You will also learn about the sensations you might experience. Let's look at these aspects in more detail.

Preparation for an Abdomen MRI

To achieve a clear and successful Abdomen MRI, follow these steps- Fast for about 4 hours before the exam and take your regular medications with a bit of water. If your scan requires contrast material, the physician might use gadolinium to improve the MRI images. Allergic reactions to gadolinium are rare, but discuss any potential allergies with your physician before receiving it.

For scans requiring contrast material, adhere to your doctor's instructions about when to stop eating and drinking. If the physician needs images of your gastrointestinal tract, you'll need to prepare your bowel using laxatives or enemas, and fast for 4 to 6 hours before the exam.

In terms of attire and personal items, wear comfortable clothing and prepare to change into a hospital gown when you arrive at the radiology facility. Leave all personal items, especially metal objects like jewellery, at home to prevent any interference with the MRI machine. If you have an artificial cardiac pacemaker or any implanted metal in your body, inform your physician as they might suggest alternative radiological examinations like a CT scan.

If you feel anxious in confined spaces, tell your physician, who may provide medication to help you relax. However, if you receive such medication, arrange for a ride home after the exam. If you're preparing for a pelvis MRI, drink plenty of fluids before the exam to ensure a full bladder.

With these preparations, you're ready for your Abdomen MRI. Next, we'll discuss what you can expect during the procedure.

During the Abdomen MRI

The Abdomen MRI procedure starts with you lying face up on the MRI table. The technologist slides the table into a large, tunnel-shaped magnetic scanner. The scanner makes a series of humming, clicking, and knocking sounds, but you won't feel anything. In some scenarios, the MRI technologist might inject a contrast agent, or dye, into a vein in your arm or hand. This injection helps capture more detailed images and takes about 1 to 2 minutes. After the injection, the technologist performs more MRI scans.

For certain MRI tests, you might receive a medication like glucagon to slow down your bowel movements. The technologist instructs you on when and how to breathe during the scan. It's crucial to stay as still as possible because the MRI machines react extremely to movement. At times, the technologist might ask you to hold your breath while capturing images. The technologist remains in contact with you during the scan and provides you with an emergency device. You can use this device to alert them if you need help.

The procedure doesn't cause any pain, but you might feel enclosed. However, the use of wide-bore MRI scanners has significantly reduced this feeling for most patients. Now that you understand the procedure, let's discuss what happens after the scan.

Interpreting the Results of an Abdomen MRI

If you've just completed an abdomen MRI, you might find the report filled with medical terms and findings that seem challenging to understand. Fear not, this section aims to simplify your report for easy comprehension. So, let's begin the process of understanding your Abdomen MRI report.

Understanding Your Abdomen MRI Report

Understanding your Abdomen MRI report is vital for your active involvement in your healthcare. The report divides into several sections, each delivering crucial insights into your abdominal health:

  1. 'Type of exam': This section states the date and type of exam.
  2. 'History/Reason for exam': This section details your symptoms and the test's reason.
  3. 'Comparison/Priors': This section enables the radiologist to compare the new exam with any previous ones you've had.
  4. 'Technique': This part describes the exam process, including the use of contrast or not.
  5. 'Findings': This section, the most crucial part, summarises the findings and suggests potential causes.

Your Abdomen MRI offers a detailed view of various parts of your abdomen, including:

  • Organs: liver, spleen, and pancreas
  • Parts of the bowel
  • Lymph nodes
  • Blood vessels

It can identify cancers, inflammation, and provide a better visualisation of the blood supply of organs and blood vessels.

In a normal scenario, your organs and blood vessels should appear normal in size, shape, and location. There should be no abnormal growths or blockage in the ducts draining the liver, gallbladder, or pancreas. However, if any organ is too large, too small, or in the wrong place, or if there are areas of scarring or injury, or signs of infection, it may indicate an abnormality. Understanding this will allow you to better comprehend the results of your Abdomen MRI and take an active role in your healthcare decisions.
