Magnetic Resonance Imaging (MRI)

MRI is a safe, non-invasive imaging technique that uses a strong magnetic field and radio waves to create detailed, high-resolution images of organs and tissues inside the body. Unlike X-rays or CT scans, MRI does not use ionizing radiation, making it ideal for diagnosing a wide range of conditions, from joint and spine issues to brain and internal organ abnormalities. It helps radiologists diagnose and monitor many medical conditions safely and accurately.

How is an MRI performed?

Understanding the MRI Process

During an MRI, the patient lies on a movable table that slides into the MRI scanner. A specialized device called a coil may be placed over or around the body part being examined. This coil sends and receives radio signals from the body, allowing the scanner to capture detailed images. While the patient lies still, the magnetic field and radio waves work together to create the images. The scan is painless, but hearing protection will be provided as it involves very loud tapping and knocking sounds. The examination may include the use of a contrast agent, given intravenously to improve image detail.


How Should you prepare?

You will be contacted approximately one week prior to your appointment to complete a screening form of your medical and surgical history. If fasting is required for your examination, you will be notified when screened. Some medical implants such as pacemakers, aneurysm clips, and drug pumps are contraindications for MRI, making the exam not suitable for everyone. On the day of your appointment please arrive at least 30 minutes before your scheduled exam time, to allow sufficient time to be re-screened and properly prepared. You should wear comfortable clothing without metal, and all jewelry and metal accessories must be removed before the exam; you may also be asked to change into a gown. Following your MRI, the images will be reviewed by a radiologist, and results are typically available within 2–3 business days.

  • Fasting Instructions for Abdominal Imaging:

    Please do not eat or drink anything for four (4) hours prior to your MRI examination. You may continue to take your prescribed medications as directed by your physician unless you have been instructed otherwise. If the medication requires a small sip of water, this is permitted.

  • Claustrophobic Patients:

    We do not provide sedatives for MRI exams. If you need medication for anxiety, you must bring a prescribed sedative and know the correct dose. Take it 15 minutes before your appointment and arrive with a driver, as you will be legally impaired after the examination. Following these steps ensures your safety and a smooth MRI experience.
