A magnetic resonance imaging (MRI) scan, is a non-invasive diagnostic tool that uses a strong magnetic field and radiofrequency waves to provide detailed pictures of internal organs and tissues.
To better visualize these organs, a contrast material may be used.
It can aid in locating pathologic conditions that may not be found with a general X-ray or CT.
Our radiology department aims for customer satisfaction and comfort.
That is why we now have several state-of-the-art MRI machines, including one that provides more headroom, shorter exam times and better quality images. It accommodates people of varying sizes and is ideal for claustrophobic patients.
Both our diagnostic radiology locations offer MRIs. Call 410-328-3225 for an appointment.
Because an MRI uses a magnetic field, special precautions need to be taken and an MRI might not be able to be done, under the following circumstances:
- A pacemaker
- Some cerebral aneurysm clips
- Cochlear implants
- Certain types of metallic implants
You will change into a gown and remove all metal objects including jewelry, watches and hairpins as well as false eyelashes and hair glue, if you are getting head imaging. Dyes used in tattoos may contain iron and could heat up during MRI, but this is rarely a problem.
Purpose for MRIs
MRIs can be used to visualize nearly any part of the body including the brain, liver, kidneys, spleen, pelvis, blood vessels and spine. It may be performed with or without an intravenous contrast, depending on what your doctor would like to have visualized.
Functional brain MRI is a diagnostic tool that measures quick, tiny metabolic changes taking place in an active part of the brain. Like a PET/CT scan, it is used to examine the anatomy of the brain and its functions to better diagnose and treat brain disorders and abnormalities.
MR imaging is also used to guide treatment during interventional radiology procedures. For instance, MRI-guided focused ultrasound is an innovative treatment for essential tremors.
