Diagnosing Stroke, Brain & Neurological Conditions

Under the expert guidance of our neurosciences team at Portsmouth Regional Hospital, you can expect an accurate and prompt diagnosis of your particular neurological condition.

Comprehensive Diagnostic & Imaging Services

Through our extensive network of resources, you have full access to the latest diagnostic tests and imaging services. Our staff of board-certified radiologists and technologists works closely with your physician throughout your entire journey, from diagnosis onward.

We offer the Seacoast Region's only neurological ultrasound equipment dedicated to life-saving emergency care. In addition, you'll benefit from advanced technologies used by our interventional neuroradiologists that combine diagnosis and treatment to address your situation quickly.

  • High-density magnetic resonance imaging (MRI) and computed tomography (CT) scanning deliver detailed images of tumor, stroke or injury locations and conditions or the status of nerves, arteries and vessels in the hands, arms, legs and feet, which improves accuracy during surgery or treatment and spares tissue and function.
  • CT angiography visualizes blood flow throughout the body and helps identify narrowing areas that need correction.

Based on information from your physical exam, medical history and any previous screening or testing, your physician may recommend and refer you for additional diagnostic testing, such as:

  • Electroencephalogram (EEG) or brain wave test – Detects problems in electrical activity of the brain that may be involved with multiple sclerosis, Parkinson's disease, migraine, sleep issues, balance and dizziness disorders or post-concussion syndrome
  • Electromyography (EMG) or myogram – Checks the health of muscles and the nerves that control muscles to determine muscle strength impairment
  • Nerve Conduction Velocity (NCV) – Tests the speed of electrical signals through a nerve to determine nerve damage or destruction or muscle or nerve diseases such as myasthenia gravis and others; often performed with an EMG
  • Evoked Potentials (EP)– Measures electrical signals to the brain generated by hearing, touch or sight to assess nerve condition
  • Visual Evoked Potential (VEP) – Looks for problems in the brain that affect vision, including multiple sclerosis; also used to test vision in children and adults unable to read eye charts
  • Somatosensory Evoked Potential (SSEP) – Measures response from stimulating nerves in arms and legs to detect nerve or spinal cord damage or nerve degeneration
  • Brainstem Auditory Evoked Response (BAER) – Measures brain wave activity in response to clicks or specific tones; helps diagnose or assess neurological function, nervous system problems and hearing loss, especially in low-birth-weight newborns
