Intrathecal CT Intrathecal CT determines blockages or flow of cerebral spinal fluid around the spinal column. A local anesthetic is injected into the lower back to numb the area. A dye is injected. This procedure is followed by a CT scan which takes a series of detailed pictures of the spinal area. Electrodiagnostics Electrical testing of the nerves and spinal cord may be performed before, during and after surgery.
Bone scans are also accurate for finding lesions for biopsy or excision.
Approximately three hours after the tracer has been injected into a vein, a scan takes place. Discography Discography is a procedure used to determine the internal structure of your disk. It is performed by using a local anesthetic and injecting a dye into your disk under X-ray guidance. An X-ray and CT scan are performed to view the appearance of the disk composition to determine if its structure is normal or abnormal. In addition to your disk appearance, your doctor will note if you have pain with this injection.
