Magnetic Resonance Imaging (MRI) with 3D Reconstruction

What Is an MRI Scan Used For?

MRI scans are commonly used to diagnose and monitor a wide range of conditions, including but not limited to: brain and spinal cord issues (e.g., tumors, multiple sclerosis), heart and blood vessel problems (e.g., aneurysms, blockages), joint injuries or arthritis, abdominal and pelvic organ abnormalities, and soft tissue injuries or tumors. They can also guide biopsies or surgical planning by offering precise images of tissues.

How Is an MRI Scan Performed?

You’ll lie down on a table that slides into a large, closed tube (the MRI machine). A technician will monitor you from another room but can communicate with you through an intercom. You may be given contrast dye to enhance visibility of certain structures. The scan itself is painless but may involve loud noises, so earplugs are provided. The procedure typically takes 15–90 minutes, depending on the area scanned.

Preparation Before an MRI Scan

Most people don’t need special preparation, but you may be asked to remove jewelry, clothing with metal, or any items that could interfere with the scan. Avoid using any lotions, powders, or creams on the scan area. If you’re pregnant, have metal implants (e.g., pacemakers, cochlear implants), or have severe anxiety, inform your doctor beforehand. Some patients may need to fast or avoid certain medications.

Potential Risks and Side Effects

MRI scans are generally safe, but risks include allergic reactions to contrast dye (rare) or motion-related artifacts if you move during the scan. You may feel warm or experience mild discomfort from the table or noise. Long scans could cause fatigue, and some patients report a sense of claustrophobia. Rarely, MRI can cause overheating if you have certain medical devices or implants.
