Tests & Screenings

An accurate diagnosis is the first step to getting better. At Fountain Valley Regional Hospital and Medical Center, we provide a wide range of tests and screenings at our fully equipped Imaging Services. See how we can get you on the road to a life without neck or back pain.

Computerized tomography (CT) scan

A computerized tomography (CT) scan is a test that involves combining X-rays taken from multiple angles to form a cross-sectional image of blood vessels and soft tissues.

Endoscopic disk stimulation diagnosis

An endoscopic disk stimulation diagnosis involves injecting disks near the site of back pain with a small amount of contrast fluid. When the patient feels pain, the physician can visually observe the site of pain using an endoscope.


An epiduroscopy involves using an epiduroscope to visually examine the epidural space, or area that contains the nerves that connect the spinal cord and the rest of the body. This test is used to check for inflammation and scar tissue in the nerve roots.

Facet medial branch block

A facet branch block involves injecting a local anesthetic and a steroid into a nerve near a spinal joint to diagnose the source of spinal pain based upon the quality and duration of the relief obtained.

Magnetic resonance imaging (MRI)

Magnetic resonance imaging (MRI) is a diagnostic technique that creates detailed images of organs and tissues using a magnetic field and radio waves.

Pain mapping

Pain mapping is a diagnostic technique in which a physician probes sensitive areas and asks the patient to rate the pain. This technique can be minimally invasive and creates a detailed map of sensitive areas.

Provocative arthrography

Provocative arthrography is a procedure in which contrast dye is injected into the joint space and X-rays are taken. The dye injections may provoke symptoms and pain.

Provocative manometric discography

Provocative manometric discography is a diagnostic procedure in which contrast dye is injected into problematic discs and CT scan images are taken. The dye injections may provoke symptoms or pain.

Selective nerve root block

A selective nerve root block involves injecting local anesthetics and steroids near a spinal nerve root that is suspected of causing pain. It can be used to determine which spinal nerve root(s) are causing symptoms such as pain.
