Diagnostic testing

Getting an early, accurate diagnosis is the first step toward a healthier life

If you think you might be at risk for stroke or have a neurological disorder, you want an early, accurate diagnosis that will support your doctor’s prevention or treatment plan and put you on the road to good health.

The physicians, nurses and technicians at Novant Health UVA Health System specialize in advanced imaging and treatment options for neurological disorders and injuries.

  • Angiography /Neuroangiography – A test used to outline the presence and position of blood vessels in the brain. After injection of a dye into a deep artery, X-rays follow its flow throughout the blood vessels of the brain. Angiography aids in the diagnosis of stroke, aneurysm, arteriovenous malformation (AVM), tumor, clot and arterial stenosis.
  • Biplane angiography – This test creates 3-D brain images. It is used in patients who have aneurysms, arteriovenous malformations (AVMs) and other conditions to determine the exact location of the problem before surgery.
  • Computed tomography (CT) – Uses an advanced X-ray machine and a computer to create a detailed picture of the body’s tissues and structures. It can help physicians determine the location and cause of a problem. It can also help them detect swelling and bleeding.
  • Developmental screenings – Help identify children who should have a more in-depth assessment for potential developmental delays. They can allow for earlier detection of delays and improve children’s well-being and plan of care.
  • Electroencephalogram (EEG testing) – Measures and records the electrical activity of your brain using sensors (electrodes) attached to your head.
  • Electromyography (EMG testing) – Measures how muscles and nerves respond to electrical activity. It helps diagnose muscle conditions that can cause muscle weakness such as muscular dystrophy and nerve disorders.
  • Functional magnetic resonance imaging (fMRI) – Clinical fMRI brain-mapping technology is a leading-edge tool. Patients who may have a brain tumor, epilepsy, a movement disorder or an arteriovenous malformation (AVM), as well as stroke survivors, can benefit from this advanced technology, which can be used by neurosurgeons before and during surgery and also for the evaluation of neurological deficits.
  • Magnetic resonance imaging (MRI) – Uses a magnetic field to distinguish healthy and diseased tissue. MRI is better than CT for areas located near bone and provides images from multiple angles, giving your physician a 3-D image of your condition.
  • Transcranial Doppler – This leading-edge vascular diagnostic technology helps prevent vascular disorders including stroke. Patients at risk for stroke are monitored for clots in their bloodstream. If no clots are found, they are reevaluated six months later. This technology is also used to look for patent foramen ovale (PFO), one cause of stroke. This is called a bubble study. Transcranial Doppler is also used to manage the ongoing care of stroke survivors; it can detect increased narrowing in the arteries of the brain and determine how well the brain has adjusted after a stroke.

Novant Health UVA Health System offers diagnostic testing services at our convenient imaging locations. A physician referral is needed for most tests.
