What is a MRI scan? MRI (magnetic resonance imaging) is an imaging modality used to produce high quality images of the body, without the use of x-rays. Instead, it uses a strong magnetic field, radio waves, and a computer to produce 3D images of different parts of the body. At The Washington Hospital, state-certified radiology technologists perform these examinations. Radiologists, who specialize in this type of imaging, will then interpret the exam. What are some reasons an MRI exam is performed? MRI is the most sensitive imaging exam for spinal and joint problems. It gives clear images of soft tissue structures near and around the bones. In sports related injuries, the MRI images allow the radiologist to see very small tears and injuries to ligaments and muscles. Chest, abdomen and abdominal vessels can also be imaged with MRI. MRI of the heart, aorta and coronary arteries is a non-invasive tool for diagnosing coronary artery disease and heart problems. What kind of MRI scanner will be used for my exam? The Washington Hospital utilizes two Siemens MRI scanners, which are the most advanced systems available today. Will I experience claustrophobia? Claustrophobia is defined as the fear of confined spaces. The Washington Hospital has a “short bore” MRI scanner, which means it is wider and shorter (similar to the CT scanner) and does not completely enclose the patient, making it more patient-friendly. There is constant communication between the patient and technologist via an intercom system. What are the hours of operation? The Washington Hospital performs MRI exams for outpatients at the hospital Monday through Friday from 7am-9:00pm and Saturday and Sunday from 7:30am-3:30pm. Do I need an appointment? Yes, you or your physician may call 724-250-4300 to schedule your exam. Do I need a referral or prescription to have a MRI examination? A prescription is necessary for you to have the exam. If you do not have a prescription or your doctor has not sent one to the hospital, your MRI exam may be delayed. How do I prepare for the scan? Prior to your scheduled exam, an MRI technologist will call and ask you a few questions about your health history. This “screening” is to make sure that there is not any health risks associated with you being inside of the magnet. This “screening” process is done once again after you have arrived for your exam. If you have had a history of metal in your eyes, you may have to have an xray of your eyes done prior to your MRI.
Who may not be able to have an MRI? Patients who have the following medical conditions may not be able to have an MRI:
Most of the new surgical metal implants are made of a high quality stainless steel that is non-magnetic. What must be removed before entering the MRI examination room?
What happens during the scan? You will be positioned on the MRI table. The technologist will operate the scanner from an adjoining room. You will need to lie still for periods of 3-10 minutes at a time, while a series of images are collected. You will not feel anything during the scan, but you may hear thumping, knocking or humming sounds from the scanner. We will provide earplugs or headphones during the scan to mask the noise. You can breathe freely for most of the MRI exam. Your exam will last between 30 and 60 minutes. What is contrast? Contrast is the term used for the material that is injected intravenously into a vein in your arm or hand. It is used to enhance the visibility of certain tissues or blood vessels. Few adverse reactions are reported with MRI contrast. How do I get the results? The radiologist will review the images and a signed report will be sent to the requesting physician within a few days. Urgent results will be called immediately to your doctor. Any questions? Please call The Washington Hospital MRI Department at 724-223-7113.
