Hypothesis
Can intraoperative ultrasound (IOUS) accurately assess the extent of tumor resection compared to postoperative MRI?
Conclusion
IOUS is a reliable tool for assessing the extent of tumor resection during surgery, showing high concordance with postoperative MRI results.
Supporting Evidence
- The study included 39 procedures from 36 patients who underwent tumor resection.
- The concordance of resection by IOUS and postoperative MRI was found to be high.
- The Kappa coefficient for total resection agreement was 0.8108, indicating strong agreement.
Takeaway
Doctors used special ultrasound during brain surgery to see how much tumor was removed, and it worked really well compared to the MRI taken after surgery.
Methodology
A retrospective analysis of prospectively collected data from 39 lesions in 36 patients who underwent tumor resection using IOUS and had postoperative MRI within 48 hours.
Potential Biases
All IOUS was performed by the same neurosurgeon, which may introduce a learning curve bias.
Limitations
The study had a small sample size and was conducted at a single center, which may limit the generalizability of the findings.
Participant Demographics
Of the 36 patients, 36% were women, with an average age of 51.4 years.
