Incidental Findings:

As this will NOT be a medically indicated examination, there will be no formal review of the scans and no report will be made. The MRI scan being done is designed to answer research questions, not examine you medically. This MRI scan is not a substitute for one a doctor would order. It may not show problems that would be picked up by a medical MRI scan. However, if we believe that we have found a medical problem in your MRI scan, we will ask a doctor who is trained in the reading of MRI scans, a radiologist, to help us review the images. If the radiologist thinks that there may be an abnormality in your MRI scan that requires follow-up, we will contact you and with your permission, contact your family physician and help him or her obtain the appropriate follow-up for you. No information generated in this study will become part of your permanent medical record. However, if the study detects an abnormality in your MRI scan and further follow-up is required, then this information may become part of your record.
