Exams and Tests

Myelography (Myelogram)

A myelogram (myelography) is performed to diagnose disorders of the spinal canal and cord, such as nerve compression that can cause extremity pain and weakness.

X-Rays (Radiographs)

X-ray technology is one of the fundamental types of diagnostic imaging used by different spine specialists.

Bone Densitometry Exam DEXA

Learn all about the bone densitometry examination (DEXA scan) and how to prepare yourself for it.


Fluoroscopy is a special type of x-ray used to project live images onto a monitor. Find out how this diagnostic tool can be used.

Exams and Tests Center

In the SpineUniverse Exams and Tests Center, learn the difference between x-ray and MRI—and how they differ from a CT scan.

The Cage

The cage is used primarily in the lumbar spine as a disc replacement spacer and is used in pairs - inserted one on the right side of the disc space and the other on the left to give good lateral support.

3 Ways to Protect Yourself from Radiation from Spinal Imaging

Discussing risks and benefits with your doctor shouldn’t only be about treatment—the conversation is also important during the diagnostic process.

MRI (Magnetic Resonance Imaging)

The MRI (Magnetic Resonance Imaging) test is the gold standard in imaging because of its ability to reveal the pathology of discs, nerves, and other soft spinal tissues in splendid detail.

Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging, or MRI, is a powerful diagnostic tool that produces highly detailed images of the spine and other parts of your body.

CT Scan (Computed Tomography) and CAT Scan (Computed Axial Tomography)

CT imaging uses low-intensity x-rays to create multiple, detailed pictures of the cervical (neck), thoracic (midback), or lumbar (low back) spine.

Electromyography (EMG) and Nerve Conduction Velocity (NCV) Tests

Electromyography (EMG) and nerve conduction velocity (NCV) tests may be an important part of a spine patient’s work-up by their doctor.

Discography (Discogram)

Provocative Discography is a form of discography that replicates the patient's 'discogenic' pain.

Diagnostic Tests: Bone Density, Nerve Function, Discography, Lab Tests

A bone scan, bone density scan, nerve function tests and basic lab work can help your doctor confirm the diagnosis.

Diagnostic Tests: X-Ray, CT Scan, MRI

X-ray, CT Scan and MRI are types of tests used to help diagnose certain spinal disorders. Learn about these and other diagnostic tests.
