CEUS For Intraoperative Spinal Cord Injury

"1. Before the spinal decompression surgery has started, the study team will inject the ultrasound contrast to visualize the spinal cord prior to decompression of the spinal cord.~2. After the spinal cord has been decompressed, the study team will inject the ultrasound contrast to visualize the spinal cord directly after decompression of the spinal cord.~3. Prior to completion and closure of the incision, the study team will once more inject the ultrasound contrast to visualize the spinal cord.~4. A member of the research team will follow up with study participants within a week of the procedure by phone. The research staff will also review the participants' medical record for up to 360 days after your procedure to collect information on clinical outcomes and any additional treatments, tests or procedures the study participants may have had."
