Tests & Screenings for Brain or Neurological Conditions

Finding the source of your brain or neurological condition is one of the first steps in proper treatment. At Hahnemann University Hospital, we offer a wide range of neurological diagnostic tests and screenings at our hospital location. See below for common tests and screenings.


Also referred to as arteriography, it is a medical imaging technique used to visualize the inside of blood vessels and organs. This procedure pays close attention to the heart chambers, veins and arteries.


A biopsy is the removal of a small piece of tissue, which will then be tested in lab for signs of disease or infection. Doctors typically suggest a biopsy when another medical test suggests that a body tissue is not normal.

Brain Scans

This procedure allows doctors to visualize brain activity as well as possible problems with the brain. MRI, CT scans and PET scans are all examples of different scans to visualize the brain.

Cerebrospinal Fluid Analysis

A CFS analysis is a laboratory test to examine a sample of the fluid that surrounds the brain and spinal cord. The fluid is withdrawn from the body by means of a procedure referred to as a spinal tap.

Computed Tomography

Also referred to as CT scans or computer tomography. A CAT scan produces cross-sectional images of the body using a computer and X-ray; these images can be helpful in diagnosing illness or injury.


Lumbar discography is a type of injection used to evaluate back pain patients, who have not responded to other forms of treatment. Once the injection is performed, a CT scan or X-ray is taken of the spine.


An EEG is a medical test used to detect electrical activity of the brain. This test uses electrodes that are attached to a patient's scalp; activity is recorded all of the time, even when sleeping.


An EMG is a diagnostic test to assess the health of muscles and the nerve cells that control them. EMGs are often used to diagnosis conditions such as carpal tunnel syndrome.


An ENG test is a diagnostic test that records involuntary movements of the eye caused by nystagmus. ENG can also be used to help diagnose vertigo or balance dysfunction by examining the vestibular system.

Evoked Potentials

An EP test measures electrical response from the brain when nerve pathways are stimulated. This test is frequently performed on multiple sclerosis patients.


Fluoroscopy is a type of medical imaging that uses X-rays in order to create real-time images of various regions of the body. The images are more like a movie and allow physicians to see what is going on inside functioning organs.

Intrathecal Contrast-Enhanced CT Scan

This test utilizes contrast and X-rays in order to better visualize the spinal canal as well as the spinal nerves. This test can help to diagnose problems with the neck and back.

Laboratory Screening Tests

Laboratory screening tests are a variety of labs and blood works used to screen individuals for a variety of medical conditions. Screening test can be performed at any age and tests will vary based on age.

Magnetic Resonance Imaging

MRI uses a powerful magnetic field as well as radio frequency pulses to produce retailed images of bones, organs, soft tissue and most other bodily structures. MRI does not use radiation.


This is an X-ray exam that uses contrast to detect pathology of the spinal cord — such as the location of an injury, tumor or cyst. The exam involves an injection of contrast; followed by X-rays of the spine.

Neurological Examination

This is a physical exam performed by a doctor in order to access neurological function. This type of exam looks at reflexes to help identify problems with the central nervous system.

Positron Emission Tomography

A PET scan is a specialized radiology procedure used to examine various body tissues for signs of disease; especially cancer. PET scans can also be used as a follow-up tool to help determine if disease has left the body.


This test is a sleep study that is used to diagnose problems with the brain. Polysomnography records a patient's brain waves, blood oxygen levels, heart rate and breathing.

Single Photon Emission Computed Tomography

A SPECT scan is a form of nuclear medicine imaging that shows how blood flows to organs and tissues. Prior to imaging, a radioactive tracer is injected into the blood stream for more accurate results.


Medical thermal imaging uses no radiation and produces infrared images of visible changes in the body. Thermography is a safe, noninvasive means of diagnosing a number of medical conditions.

Ultrasound Imaging

Also referred to as a sonogram, an ultrasound uses high-frequency sounds waves in order to produce images of internal organs. Because images are captured in real-time, images of blood vessels are also able to be produced.


An X-ray is a type of electromagnetic radiation that creates images of the body. X-rays can be used to diagnose disease or injury.
