A single MRI scan can last 25 to 45 minutes or longer. Please contact us at 307-634-7711 if you are scheduled for multiple examinations or scans that require sedation or contrast, as they will vary in length of time.
A traditional MRI scan requires very little preparation: If possible, do not wear any jewelry, clothing or accessories with metal (including body piercings). For MRI scans with sedation or contrast, please contact us for specific instructions.
Advise your referring provider prior to scheduling an MRI if you are or may be pregnant, if you have a pacemaker or cochlear ear implants, or if you have had any kind of brain surgery.
Before the exam, you may be asked to change into a dressing gown and remove metal items such as jewelry and body piercings. A Technologist will accompany you into the examination room and inform you of the scan or scans that will take place. If you have ever done any welding or grinding with metals, for your safety, a no-charge X-ray will be completed prior to your MRI scan to ensure that your eyes are free of metal debris.
During the exam, you will be asked to lie down on an examination table that moves through the large circular opening of the MRI scanner, which is not enclosed. You will be asked to be still during the scan. You can expect to hear knocking and buzzing sounds during the scan. If contrast material is used, it will be injected through an intravenous line.
In almost all instances, your referring provider will receive your examination results within two business days or less. Contact your referring provider for the results. If you would like to obtain a copy of your results, you may request a copy from your referring provider or by contacting us at 307-634-7711.
Dr. Daniel R. Possehn began with Cheyenne Radiology Group in 2005, after finishing a neuroradiology fellowship in California. Although Dr. Possehn can usually be found with a cup of coffee in his hand, don’t try to offer him a mug of instant joe—he’s more of a coffee connoisseur than a caffeine junky. When he’s not at work or traveling to remote destinations, he can be found jamming on the drums or enjoying a walk with his wife and their four-legged child Bear, a golden retriever.
