Magnetic Resonance Imaging (MRI)

Important MEMO re: New MRI forms 

As of February 1, 2018, the new MRI Requisition form is mandatory, and the Appropriateness Checklists is also mandatory in order to book an MRI of the knee or spine.

In the fall of 2016, the South West LHIN approved the Medical Imaging Integrated Care (MIIC) Project with a mandate to improve both patient access and appropriateness of medical imaging services in the LHIN, starting with MRI imaging.

Based on medical literature, including Choosing Wisely recommendations, radiological standards and specific surgical referral requirements, a new standard South West LHIN MRI referral form, and new Appropriateness Checklists for MRI studies of the knee and spine have been developed.

Electronic versions of the forms are available for download on the South West Primary Care Alliance website (www.swpca.ca). If you are using a different EMR system or are a paper-based office, the fillable PDF versions of the form are also available for download from the South West Primary Care Alliance website.

You can also find informational videos surrounding this implementation at www.swpca.ca. Please refer to this website for any questions or more information you may need.  


MRI stands for Magnetic Resonance Imaging. MRI uses magnetism and radio waves to produce highly detailed images of structures within the body. Woodstock Hospital’s MRI is a state of the art 1.5 Tesla magnet boasting a short scanner with a wide opening. This means more space in the MRI for our patients, increasing comfort levels and reducing anxiety due to claustrophobia concerns.

MRI is the gold-standard for imaging of many soft tissue structures throughout the body. Examinations at Woodstock Hospital include imaging of the: brain and spinal cord; internal organs of the abdomen and pelvis; joints and musculoskeletal structures throughout the body; assessment of lumps and bumps; and intravenous contrast examinations.  

MRI is a very safe exam. MRI uses no ionizing radiation (x-rays, gamma rays) and has no known lasting effects on the body. The strong magnetic field may be a safety concern for people who have specific implanted metallic devices; therefore specially trained MRI Technologists will ask many questions about your medical history to assure your safety in the MRI environment. Metallic objects are not permitted into the scan room. You will be required to remove any clothing that contains metal, jewellery, and any other metallic objects prior to your scan. Loud noises are produced while obtaining images, therefore hearing protection will be provided. Scan times vary depending on the exam requested and range from approximately 15 – 60 minutes.

MRI exams may only be obtained by written request by your physician. Your Health Care Provider will arrange for an MRI through Woodstock Hospital and provide you with your appointment time and date, along with any information you need to know prior to your examination. Please bring your Health Card to check in for your appointment. After your exam is complete, the Radiologist will interpret the exam and the results will be sent to your physician within 2 to 5 days.
