MRI images form when signals — emitted by organs, soft tissues, bone and other internal body structures — are processed by software and turned into clinical images. These signals are generated using a safe magnetic field in combination with radio waves to produce detailed pictures without the use of radiation.
MRI is used to examine all parts of the body and is useful in evaluating conditions such as:
MRI is often used as a primary diagnostic tool. The images help inform a quick, accurate diagnosis from your physician.
This non‑invasive procedure has no known side or after‑effects. Many patients find the procedure so relaxing they fall a sleep during the exam. It’s important to inform the technologist of any implants inside your body as some of these may pose a safety risk if exposed to the magnetic fields.
There’s no special preparation required for most MRI exams. Eat normally and perform daily routines without interruption. Take any medications as prescribed by your physician unless otherwise directed.
Some MRI exams do require some preparation, such as fasting. If this is the case, you’ll be informed either by our scheduling department or your physician as to what prep is required and whether medication can be taken as prescribed. If you are pregnant, please notify your physician before having an MRI exam.
A typical procedure averages 30 to 45 minutes.
Before entering the MRI room, you’ll be asked to remove any items not compatible with the magnetic field.
Once the exam begins, you will hear a series of knocking sounds. These sounds are normal and represent changes in the magnetic field. You will be asked to remain as still as possible. When the exam is finished, the technologist will help you off the table and out of the scan room.
