Imaging Studies - MRI, CT, Myelogram

 

What is a CT scan?

Commonly called a "CAT" scan, this is a type of x-ray, whic allows us to see the inside of your brain (or spinal cord). This type of scan gives us a good look inside the brain, and is a great "screening" imaging study.

 

What is an MRI scan?

An MRI scan also looks inside the brain (or spinal cord) with more detail when compared to a CT scan. But, an MRI is not always "better" than a CT scan. This technology is based on "magnets" and there are no x-rays involved.

 

What is a CT Myelogram?

Some people refer to this study as the "dye test". It is done in the hospital, and involves inserting a small needle into your lower back. Some "contrast dye" is then inserted into your spinal canal (NOT into your spinal cord). This is followed by some x-rays and CT scan of the spine. This contrast "surrounds" the spinal cord and spinal nerves, which allows us to get a "better look" inside the spinal canal.

 

Is an MRI better than a CT scan?

Each situation is different. In some instances, a CT scan is far superior to an MRI. These options should be discussed with Dr. Athni.

 

Is an MRI better than a CT myelogram for spinal problems?

There are some diseases which are better visualized with an MRI. But, in some situations, a myelogram might be more beneficial. These options should be discussed with Dr. Athni.

 

Who reads or interprets these imaging studies?

All of the above imaging studies are performed at a local hospital or an imaging facility. The films are read and interpreted by a Radiologist working at that facily.

BUT, we request that you bring your films to our office appointment, as Dr. Athni reviews the films with you. For a proper assessment, tt is very importnat to correlate your clinical symptoms with the findings seen on the imaging studies.
