Summary

This study tested whether a special ultrasound with a contrast agent (DEFINITY®) can measure blood flow in the spinal cord during surgery for acute spinal cord injury. 27 patients received the contrast agent while surgeons performed routine decompression. The goal was to see if the technique is feasible and could help doctors detect dangerously low blood flow that may worsen the injury.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Perflutren lipid microsphere (DEFINITY®)
What this could lead to: If successful, this technique could help doctors identify low blood flow in the spinal cord and guide treatments to improve outcomes after injury.
What could go wrong: This is a small, early feasibility study focused on imaging, not treatment. The technique may not prove useful or may not improve patient recovery.
