Magnetic Resonance Imaging (MRI) Services

What is an MRI?

MRI (Magnetic Resonance Imaging) takes pictures of body structure (inside the body) using powerful magnetic fields combined with radiofrequency signals. An MRI is an extremely accurate way to detect diseases, tumors, bleeding, swelling, aneurysms and many other bodily changes and abnormalities. In some cases, MRIs give information not seen through other exam methods like X-ray or CT scan.

An MRI takes several pictures to accurately examine different body parts, such as the head, chest, spine and joints. Each picture provides different information about the area’s structure.

During an MRI, the patient is placed under a magnetic machine and must lay still for the images to be accurately captured. Contrast agents may be given to the patient before imaging.

A typical MRI lasts 45 minutes, but duration can vary depending on type of examination. Results are usually available after two business days.

How to prepare for an MRI

The first step in preparing for an MRI exam is to become familiar with the procedure, so we encourage you and your child to look at the video below. If you have any questions about your exam, please call the MRI department at (559) 353-7220.

For the MRI, make sure you and your child do not wear jewelry and remove any make up. If you have new tattoos or any past surgery where something was placed in your body, let the MRI technologist know beforehand.

Feel free to bring your own music or movie if you’d like to listen or watch during the MRI. If the patient is sick, the MRI may have to be rescheduled.

If you believe your child is unable to stay still and needs anesthesia, please contact scheduling at (559) 353-9114.

What if my child needs anesthesia?

A nurse will call you 1-2 days prior to give you arrival and eating instructions. Following these instructions is critical so the patient is safe during the MRI.

The patient will be given medicine to help them hold still during the exam. If you have questions, contact nurse sedation at (559) 353-5958.
