Summary
The Airo CT scanner is a new intraoperative imaging tool for deep brain stimulation (DBS) surgery. While both Airo and O-arm CT are effective, O-arm may be better for DBS alone, whereas Airo is more versatile for combined cranial procedures.
Area of Science:
- Neurosurgery
- Medical Imaging
- Radiology
Background:
- Intraoperative computed tomography (CT) imaging, such as the O-arm CT device, is widely used in surgery.
- New devices like the Airo CT offer advantages in reducing patient transfer and improving lead placement accuracy during surgery.
- This report details the initial application of the Airo CT device in deep brain stimulation (DBS) surgery.
Purpose of the Study:
- To evaluate the application and compare the efficacy of the Airo CT device versus the O-arm CT device in DBS surgery.
- To assess patient and surgeon comfort, surgical planning, image quality, and cost-effectiveness.
- To provide insights into the suitability of each device for different neurosurgical procedures.
Main Methods:
- A retrospective study of 52 patients undergoing DBS surgery between October 2020 and November 2021.
- Involved preoperative MRI and CT scans, followed by intraoperative CT using the Airo device.
- Images were merged with neuronavigation software (BrainLab) to confirm lead placement.
Main Results:
- Both Airo CT and O-arm CT devices are user-friendly, precise, and safe.
- Each device presents distinct advantages and disadvantages depending on the surgical context.
Conclusions:
- This is the first study to report on the use of the Airo CT in DBS surgery.
- For DBS procedures exclusively, the O-arm CT may be more suitable.
- The Airo device is recommended for cases involving both DBS and additional cranial surgery due to its versatility.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
