Summary
Mobile computed tomographic (CT) scanning enhances spinal surgery by improving visualization and verifying corrections. This technology is feasible and beneficial for complex spinal procedures, impacting surgical decisions in select cases.
Area of Science:
- Neurosurgery
- Radiology
- Spinal Surgery
Background:
- Mobile computed tomographic (CT) scanners are increasingly utilized in operating rooms.
- Intraoperative CT scanning has primarily been used for intracranial procedures.
- This study explores the expanded application of intraoperative CT in spinal surgery.
Observation:
- A mobile CT scanner (Tomoscan M) was integrated into the operating room workflow.
- The system involves a translatable gantry and table, with sterile draping for intraoperative use.
- Each CT scan series takes approximately 15-20 minutes.
Findings:
- Intraoperative CT scanning altered surgical management in 6 out of 17 complex spinal cases.
- Benefits included improved visualization for craniocervical decompressions and tumor resections.
- CT verified graft and instrument placement, ensuring surgical accuracy.
Implications:
- Intraoperative CT scanning is feasible and beneficial for complex spinal surgeries.
- It aids in procedures from the craniocervical junction to the sacrum.
- The technology also shows utility in neurointerventional suites and for radiotherapy planning.
