Montwood Medical has recently purchased an MRI system to better serve you. There is no longer any need for you, our patients, to have to travel to two different locations for you health needs. Our MRI will save you time and money!
What is a MRI Scan?
MRI, or magnetic resonance imaging, is a routine diagnostic procedure. Images of the internal tissues of the human body are produced by using the tiny magnets of hydrogen nuclei which are abundant in all of us as parts of water, fat, protein, and other molecules. The large magnetic field of the MRI machine causes the hydrogen magnets to align, while applied radio waves excite them to transmit signals similar to the radio waves generated at FM radio stations. The locations of the signals within the body are identified using magnetic field gradient pulses which are the source of the loud knocking noises heard during the examination. Once enough signals have been collected, they are processed by powerful computers to generate pictures of the human anatomy in vivid detail for the radiologist to analyze and diagnose abnormalities.
Why are MRI Scans performed?
Your physician may request an MRI study for a number of reasons. MRI is often used to obtain specific diagnostic information not already provided by other imaging technologies such as ultrasound, computed tomography, and nuclear medicine. MRI may be needed to rule out disease and to facilitate medical, surgical, and other treatments for conditions of the brain, spinal column and spinal cord; eye, ear, nose and throat; bones, joints, and muscles; heart and blood vessels; chest and lungs; abdominal organs and digestive tract; and, kidneys , urinary tract, and pelvic organs. Such conditions may include congenital and developmental disorders, genetic and metabolic diseases, infections and inflammatory conditions, traumatic and other types of injury, vascular and blood diseases, and cancer conditions of childhood.
How do I prepare for a MRI Scan?
You may eat or drink as usual unless the MRI examination requires the injection or ingestion of a contrast agent for image enhancement, if sedation or anesthesia is necessary, or if there are other special care considerations. In these situations, specific dietary restrictions and other instructions are provided by your physician in advance of the appointment. It is very important to adhere to these instructions to insure your safety while undergoing the MRI examination. Otherwise, the procedure will be rescheduled to a time and date that allows for the appropriate preparation. It is also important to notify the MRI staff of any active illness, allergy, or previous drug reaction that may prevent the child from undergoing the examination safely.
How is a MRI Scan performed?
Upon arriving at the MRI suite, your appointment and registration are confirmed by the MRI scheduling coordinator. You will be asked to fill out the MRI screening questionnaire. The MRI nurse then asks a few questions and does a clinical screening examination. The patient must remove all metal objects (e.g. jewelry) and electronic devices (e.g. watch) and change into hospital attire or wear clothing from home that is comfortable and free of metal (zippers, buttons, etc.). The nurse then prepares you for the MRI procedure, which may include oral or intravenous sedation by the radiologist, or anesthesia by an anesthesiologist.
The MRI Technologist positions and secures you comfortably on a narrow bed within the large, doughnut-shaped magnet and adjusts the radio wave coil. The technologist then performs the MRI examination with the radiologist and is in contact with the patient at all times. During the MRI procedure, the patient will hear several series of repetitive pulsing noises. It is particularly important for the patient to remain still during these noises since the MRI machine is obtaining images at those times. If the first pictures are motion-free, this will help shorten the total exam time and prevent delays. An entire MRI examination may take from twenty minutes to one and a half hours depending on the type of information required by the radiologist and your physician. All patients undergoing sedation or anesthesia receive continuous vital monitoring and support.
