Medical Specialties: Diagnostics
A complete range of imaging and diagnostic services is available to physicians to help make accurate and speedy diagnosis of diseases and abnormalities. Accredited by the College of American Pathology (CAP), the laboratory at Trinity Hospital offers full service clinical and pathology procedures and conducts all standard tests. X-ray and imaging capabilities include MRI, CT, ultrasound, nuclear medicine, digital mammography and special radiology procedures. An accredited vascular laboratory within the Radiology Department provides diagnostic and therapeutic procedures. An endoscopy lab is equipped with endoscopic ultrasound equipment dedicated to the diagnosis and treatment of disorders of the gastrointestinal system.
Neurodiagnostics is a field of science devoted to recording and studying the electrical activity of the brain and nervous system. This activity is recorded using the following procedures:
Records electrical activity of the brain to diagnose and/or monitor:
Nerve Conduction Study (NCS)
Evaluates electrical potentials from peripheral nerves by recording the speed of the impulses through the nerves. The NCS is valuable in diagnosing many disorders including Carpal Tunnel Syndrome. Remember diagnosis is the first step towards treatment.
Records the electrical activity of muscles for evaluation of muscle weakness, spasms, and paralysis or pain in the arms, hands, legs or face. Performed by a specially trained physician, an EMG also can determine if a disease involves the spinal cord, nerves, muscles or the nerve-muscle junction.
Both NCS and EMG are often performed at the same appointment.
Evoked Potentials (EP)
Also called Evoked Responses. This test consists of three separate procedures, each focusing on a different nerve pathway:
Auditory Evoked Potential (AEP)…Evaluates the nerve pathway from the ear through the brainstem and provides the physician with information regarding hearing integrity and brainstem function.
Somatosensory Evoked Potential (SEP)…Checks the pathway from limb nerves to the brain. The SEP studies the function of the spinal cord and nerves in the limbs.
Visual Evoked Potential (VEP)…Checks the pathway from the eyes to the brain and may help find the cause of vision problems or other conditions such as M.S. or optic neuritis.
