Bone Densitometry Exam DEXA

A bone densitometry exam, also known as a bone density test, bone mineral density test, or dual energy x-ray absorptiometry (DEXA or DXA) diagnose osteoporosis or osteopenia, and assess your risk for fracture.

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

CT scans, known as CAT scans or computed tomography, are imaging tests performed to evaluate the cause of spinal disorders and back pain. CT imaging involves low-intensity x-rays to create detailed pictures of the cervical (neck), thoracic (mid back) or lumbar (low back) spine.

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.

Bone Grafts: New Developments

The use of BMP-2 in spinal fusions will eliminate the need for taking the patient's own bone.

Electrodiagnostic Tools

Electrodiagnostic studies should be considered an extension of the history and physical examination and not a substitute for a detailed neurologic and musculoskeletal examination.

MRI vs. Myelogram

There are several advantages to having a myelogram to help diagnose your back pain, in addition to an MRI scan. Article describes both the benefits and drawbacks of myelograms.

Diagnostic Tools: X-Ray, Bone Scan, MRI, CT Scan

Spine specialists use x-rays, bone scans, MR imaging, and CT scans to confirm a diagnosis.

Nuclear Imaging: PET and SPECT Scans

As part of the family of nuclear imaging techniques, PET and SPECT scans are performed to detect abnormal metabolic activity, which could lead to structural changes (in the vertebrae, for example).

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.

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.
