Intraoperative sonography through a burr hole: guide for brain biopsy
AJNR. American Journal of Neuroradiology
|May 1, 1984
Summary
Real-time brain sonography via a burr hole accurately imaged tumors. This intraoperative ultrasound technique enhances flexibility and greatly aids brain biopsy procedures.
Area of Science:
- Neurosurgery
- Medical Imaging
- Neurology
Background:
- Intraoperative imaging is crucial for neurosurgical procedures.
- Accurate visualization of brain structures and lesions is essential for successful biopsies.
Purpose of the Study:
- To evaluate the feasibility and accuracy of intraoperative sonography through a burr hole for brain tumor imaging.
- To assess the utility of this technique in facilitating brain biopsy.
Main Methods:
- Sonographic imaging of the brain was performed in five patients using a small, real-time, 5 MHz transducer inserted through a burr hole.
- Brain tumor imaging was compared with computed tomography (CT) scans for morphological correlation.
Main Results:
- Sonographic imaging successfully visualized brain tumors in all five patients.
- The morphology of the imaged tumors closely corresponded to findings on CT scans.
- Intraoperative sonography provided real-time imaging and flexibility during the procedures.
Conclusions:
- Intraoperative sonography through a burr hole is an accurate method for brain tumor imaging.
- This technique offers significant advantages in flexibility and procedural facilitation, particularly for brain biopsies.
- Sonography represents a valuable adjunct to existing neuroimaging modalities in surgical settings.
