Diagnostic Testing

Riverside is the only local healthcare system where the latest and most advanced neurological diagnostic technology available, the 128-slice CT scanner, is used. It provides physicians with a view of the brain almost twice as detailed as that of traditional 64-slice CT scanners and in critical situations where seconds count, doctors are able to quickly and more accurately diagnose and treat brain trauma and disorders.

Our medical teams perform thousands of tests each year and all diagnostic test results are sent to the patient’s physician as well as entered into the patient’s electronic medical record. Riverside physicians have 24/7 access to their patient’s electronic medical records making diagnostic reporting, patient notifications and development of a treatment plan much faster.

The most common tests used to properly diagnose and treat neurological conditions include:

CT scan (Computed Axial Tomography)
A CT (also called CAT) scan is short for “computer assisted tomography” and is a valuable diagnostic tool for neurological, heart and vascular specialists. CT scans are more detailed than general x-rays, using computers to generate a three-dimensional image from flat, two-dimensional x-ray pictures. Riverside utilizes the innovative 128-slice CT scanner which provides twice the imaging power and half the radiation of conventional scanners.  It is the only locally available 128-slice CT scanner. This technology can produce three-dimensional images of the brain or spinal cord within seconds. Riverside specialists use CT scanners to accurately locate blockages and other conditions so they can determine the best treatment option. By combining non-interventional and interventional radiology procedures, more accurate images are obtained and better patient outcomes are achieved.

Electromyogram (EMG)
This test records electrical activity of muscles. Active muscles produce an electrical current which is usually proportional to the level of muscle activity. An EMG is also referred to as a myogram.

Positron Emission Tomography (PET)
A PET scan measures important body functions, such as blood flow, oxygen use, and sugar (glucose) metabolism, helping doctors evaluate how well organs and tissues are functioning. For neurological patients, PET scans are most commonly used to detect brain tumors as well as memory, seizure and other central nervous system disorders.

Electroencephalogram (EEG)
An electroencephalogram (EEG) is a test that measures and records the electrical activity of the brain. Certain conditions, such as epilepsy, can be detected based on changes in the normal pattern of the brain's electrical activity.
