Ordered in patients with hearing loss or vertigo. The two main categories of hearing loss are conductive and sensorineural. MRI is the test of choice for sensorineural hearing loss. For conductive hearing loss, CT is the modality of choice, which can assess the ossicular chain, as well as other conductive abnormalities in the external and middle ear (Paget disease, fibrous dysplasia). This study should be ordered without and with contrast.
For the MRI exam, if you are claustrophobic or anxiety is a problem, your referring physician may wish to prescribe a mild sedative to be given prior to the study. A current creatinine (within 45 days) is needed on all patients over the age of 60, as well as patients that have high blood pressure, diabetes, acute vascular disease, or a history of kidney disease. Please have your physicians fax these results with the order.
Patients will need to remove all jewelry, hairclips, pony-tails and bobby pins. In addition, the patient will need to remove all clothing containing metal. This would include bras with metal enclosures and jeans with metal zippers and buttons. Your patient will be provided a gown and a secure locker in which valuables can be placed.
Our MRI equipment has a weight limit of 440 pounds.
MR imaging uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. MRI does not use ionizing radiation (x-rays). Detailed MR images allow physicians to better evaluate various parts of the body and determine the presence of certain diseases that may not be assessed adequately with other imaging methods.
Patients with cardiac pacemakers, ICD, or neuro-stimulators CAN NOT have an MRI. Patients with pins, plates, screws and joint replacements, stents & filters can have an MRI as long as it has been 6 weeks since placement of the device. Women who are pregnant should avoid having an elective MRI. Women who are pregnant and need an MRI should be individually evaluated for risk vs. benefits and should avoid an MRI in the 1st trimester of pregnancy.
Although the strong magnetic field is not harmful in itself, implanted medical devices that contain metal may malfunction or cause problems during an MRI exam.
There is a very slight risk of an allergic reaction if contrast material is injected. Such reactions usually are mild and easily controlled by medication. If you experience allergic symptoms, a radiologist or other physician will be available for immediate assistance.
Nephrogenic systemic fibrosis is currently a recognized, but rare, complication of MRI believed to be caused by the injection of high doses of MRI contrast material in patients with very poor kidney function.
You will be asked to lie down on his back on the scanning table. The table will then slide into the scanning area. During the test, the MRI will make a rapid tapping noise. Some MRI examinations may require an injection of contrast material into a vein in the arm. Your experience and comfort are of key importance. Therefore, you can watch TV, be offered earplugs or a music headset; in addition blankets are also available. You should relax and remain still during the exam. Plan 60-90 minutes of total clinic time. The scan time can vary from 30-60 minutes depending on the study. You may resume normal activities following the MRI.
A radiologist will analyze the images and send a signed report to the referring physician within 1 business day.
