Recent advances in imaging technology now allow neuroradiologists to more accurately pinpoint the source of patients' back or neck pain, resulting in a more effective and prolonged response to treatment. UCSF Medical Center is one of the few centers in California to offer the latest generation of CT technology, the 64-slice CT scanner .This technology allows neuroradiologists to inject medication adjacent to nerves, within joint spaces or around the spinal canal with greater precision.
During spinal intervention procedures, the 64-slice CT scanner may be used in combination with other diagnostic imaging techniques available at UCSF, including MRI and myelography. Our three-dimensional imaging procedure provides neuroradiologists with the best images available for viewing your spine’s anatomy, and our MRI imaging techniques allow direct visualization of inflamed nerves.
Our radiologists have pioneered low-radiation techniques for spinal procedures using CT, which result in radiation doses that are similar or less than those from conventional X-ray fluoroscopy guidance.
CT-guided spine injection procedures may be particularly beneficial to patients who:
CT-guided spinal injections offer several advantages compared to the technique most commonly used to guide back and neck pain injections, called X-ray fluoroscopy.
Real time, three-dimensional CT guidance is used during procedures to precisely guide needle placement and the delivery of the pain medication to the appropriate location. This improves our patients' chances of a successful diagnosis and treatment.
Using CT, neuroradiologists can visualize structures that do not appear on routine X-ray-based fluoroscopy, such as subtle fractures, disc herniations or bony spurs. These conditions may cause or contribute to back or neck pain. In many cases, the underlying cause of a patient's back and neck pain is discovered during CT scanning for the injection procedure. If this occurs, the therapy originally planned may be altered to treat your pain more effectively.
The procedure for a single injection typically takes less than 30 minutes. Depending on the number of injection sites and the complexity of the treatments, however, the procedure may take as little as 15 minutes or as long as one to two hours.
You will be given discharge instructions of what to expect after the procedure. For more information, please call our Precision Spine Center nurse at (415) 353-3717. Our nurses are available to assist you before, during and after the procedure.
As with any procedure that uses radiation, there are small risks. However, our neuroradiologists use every available technique to minimize your radiation exposure while achieving the best outcome possible.
The new 64-slice scanner, unlike earlier models, quickly records and processes images. Its enhanced speed allows your neuroradiologist to remain in the procedure room as images process and, as needed, to quickly redirect the course of the needle path using three-dimensional imaging.
By using low-dose scanning and reconstruction methods, procedure time can be reduced by as much as 75 percent while achieving radiation doses typical of the usual two-dimensional X-ray imaging techniques. The combination of CT and advanced, low-dose technique results in a more effective and safer procedure.
Most spine procedures can be scheduled within five to seven business days. Every effort will be made to accommodate urgent requests within two days. In addition, spine interventional studies, CT, MRI and PET/CT examinations may be scheduled on the same day.
