Summary
Portable head computed tomography (CT) scans in the operating room altered surgical plans in 32% of cases. This intraoperative imaging provides a valuable alternative, potentially avoiding repeat surgeries.
Area of Science:
- Neurosurgery
- Radiology
- Medical Imaging
Background:
- Intraoperative imaging is crucial for surgical decision-making.
- Portable computed tomography (CT) provides an accessible imaging solution when MRI is impractical.
- This study evaluates the utility of portable head CT in the operating room.
Observation:
- A retrospective review of 50 portable head CT scans performed in the operating room at the University of New Mexico between May 2007 and March 2010 was conducted.
- The average operative time was 121 minutes, with reservoir placement averaging 54 minutes.
- Procedures included reservoir placement (28%), tumor resection (24%), and cerebrospinal fluid shunting (24%), among others.
Findings:
- Portable head CT scans were utilized in 50 cases over a 3-year period.
- In 16 of these cases (32%), findings from the intraoperative CT scan led to modifications in the surgical plan.
- The study analyzed various neurosurgical procedures, including tumor resections and CSF shunting.
Implications:
- Intraoperative portable head CT can significantly alter surgical plans in a substantial percentage of cases (32%).
- This technology may help prevent the need for patients to return to the operating room for further imaging or intervention.
- Portable intraoperative CT offers a cost-effective imaging alternative compared to fixed intraoperative imaging suites.
