To assess the challenges in tumour boundary detection using intraoperative ultrasound (iUS), specifically focusing on interobserver variation and imaging accuracy among experienced operators.
Key Findings:
iUS has a 77% gross total resection rate in glioma surgery, comparable to other navigation methods, indicating its effectiveness.
iUS shows 72.2% pooled sensitivity and 93.5% pooled specificity in assessing diffuse glioma resection, highlighting its diagnostic potential.
Challenges in tumour boundary detection include interobserver variation and imaging accuracy, which may affect surgical outcomes.
Interpretation:
The study highlights significant challenges in the segmentation of brain tumours using iUS, emphasizing the need for improved training and techniques to enhance accuracy and reduce interobserver variability.
Limitations:
Limited number of annotators and images may affect generalizability of the findings.
Variability in operator experience could influence results, potentially skewing the assessment of interobserver variation.
Conclusion:
Addressing segmentation errors and improving training and tools are essential for the broader adoption of iUS in brain tumour surgeries, ultimately aiming to enhance patient outcomes.
