Radiation dose reduction for computed tomography-based navigation in endoscopic sinus surgery is feasible. Reduced radiation doses maintained registration accuracy, limited only by surgeon-determined image quality needs.

Area of Science:

Medical Imaging
Otolaryngology
Radiation Oncology

Background:

Computed tomography (CT)-based navigation is widely used in endoscopic sinus surgery.
Concerns exist regarding iatrogenic radiation exposure and cancer risk.
Limited research addresses radiation dose reduction for CT-based navigation systems.

Purpose of the Study:

To validate the use of reduced radiation dose CT for surface registration in computer-aided sinus surgery (CAS-CT).
To assess the impact of dose reduction on the precision of surface registration techniques.

Main Methods:

Human cadaver heads were scanned using dose-reduced CAS-CT protocols (1.1-9.6 mGy) compared to a reference dose (65 mGy CTDI).
Target registration error (TRE) was measured to evaluate registration accuracy at different dose levels.

Dose reduction protocols were tested in clinical practice for 12 months.

Main Results:

Registration accuracy (TRE) did not significantly differ between the highest and lowest radiation doses.
Technical registration accuracy was preserved across tested dose reduction protocols.
The primary limitation to dose reduction was the surgeon's tolerance for diminished image quality.

Conclusions:

Surface registration accuracy is not the limiting factor for dose reduction in CAS-CT.
Significant radiation dose reduction (6-fold, from 65 mGy to 9.6 mGy CTDI) is achievable for most procedures.
This demonstrates potential for dose reduction in similar radiological applications.
