The benefits from the first shot only lasted 2 weeks. The second and third set of injections lasted about 90 days. In November, I was ready to have surgery. My EMG and nerve conduction tests proved that the nerves were "sleeping" before I was. After another MRI, the neurosurgeon said I was a candidate for surgery but I was not able to get the endoscopic type surgery that is less invasive. I would have an incision about 6-8" long. Along with removing the herniation, they would have to increase the size of the hole where the nerve roots were going through.
CT guidance has been shown in published medical studies to result in more accurate and precise placement of needles and medication, resulting in better patient care. We have tailored our CT technique to minimize radiation dose and have shown that the radiation levels for injections with CT guidance are at or below the levels that occur with conventional fluoroscopy. In fact, to further minimize the patient’s exposure to radiation we often limit the scan to just one or two segments that are of importance instead of scanning the entire spine.
