Fasting – before undergoing a pelvic or abdominal MRI scan, you will be advised not to eat or drink for at least five hours before the procedure.Tell your doctor if you are pregnant or if you think you may be pregnant. Pregnancy – the affect of MRI scanning on a fetus is unknown.Don’t ever have an MRI scan if you have a heart pacemaker! Tell your doctor about any internal device or implant you may have, such as a heart pacemaker, metal pins or a medication pump. Metal – some metal objects can be affected by the magnetic field of the MRI scan.Medical considerations prior to the MRI scan may include: That is why bone injury or disease is usually investigated with regular x-ray examinations rather than MRI scanning. However, it can’t ‘visualise’ bone very well, since bone tissue doesn’t contain much water. The MRI scan provides clear and detailed images of soft tissue. Injury or disease of internal organs including the brain, heart and digestive organs.Soft tissue injuries such as damaged ligaments.The MRI scan is used to investigate or diagnose conditions that affect soft tissue, such as: The MRI scan operator (radiographer) can take cross-sectional images of the patient’s body from almost any angle. A computer then organises these echoes into images. The magnetised protons in the soft tissue send out an echo in response to the MRI scan’s radio waves. Soft tissue contains water molecules and the magnetic field acts upon microscopic substances (called protons) found in water. Inside the cylinder is a magnet that, when operated, creates a powerful magnetic field. The MRI scan consists of a table that slides into a large cylinder. This allows high-resolution pictures of many organs and tissues to be taken that are invisible to standard x-rays. MRI scans image water, which makes them very useful because all tissues of the body contain various amounts of water. Normal x-rays image calcium, so they are good to see bones. One way to think of an MRI scan is a water ‘x-ray’ (although no actual x-rays are involved). It is especially helpful to collect pictures of soft tissue such as organs and muscles that don’t show up on x-ray examinations. It uses a magnetic field and radio waves to take pictures inside the body. Magnetic resonance imaging (MRI) is a scan used for a medical imaging procedure.
