Specialized Diagnostic Services

24 Hour Electroencephalographic (EEG) Monitoring. Brain wave electrodes are attached to a portable recorder which is carried for 24 hours to study the brain's electrical activity to aid in the diagnosis of seizures and other neurological conditions.

Arteriogram (angiogram). An X-Ray where dye is injected into an artery to study the blood vessels supplying the brain and within the brain.

Carotid Ultrasound Testing. This test permits us to diagnose abnormalities of the carotid artery, such as arteriosclerosis, using safe and painless high frequency sound waves without radiation.

Computerized Axial Tomography (CT or CAT Scan). A computer-assisted X-Ray which constructs sophisticated, two dimensional pictures of the body, head and spine to aid in the diagnosis of many disorders of the brain, spine, lungs, abdomen and pelvis. In some instances, intravenous dye is used to obtain a better picture.

Electrodiagnostic Testing (EMG & Nerve Conduction Tests). Through mild electrical stimuli, this test measures the electrical activity in muscles and the functioning of nerves for the diagnosis of various disorders of the nerves, muscles and spinal cord. As small needles are inserted to transmit and record the electrical activity, this procedure may cause slight discomfort.

Evoked Potentials Testing. Disorders of the nerves, spinal cord and brain stem as well as visual and hearing pathways can safely and effectively be studied by this test, which combines electrodiagnostic studies and sophisticated computerized EEG recordings.

Magnetic Resonance Imaging (MRI)/Angiography. Using a powerful magnetic field, radio-waves, and computer reconstruction, MRI produces high resolution images of the brain, spine, joints, chest and abdomen. Vascular imaging studies can also be provided with MR Angiography. The imaging process is non-invasive, safe and painless without using radiation.

Myelogram. Contrast medium is injected into the back to aid in diagnosis of herniated discs of the cervical and lumbar spines as well as many other spinal disorders.

Transcranial Doppler Studies. Transcranial Doppler uses the same painless high frequency sound waves as carotid ultrasound to examine the arteries inside the brain to help treat and prevent strokes.
