Navigation systems improve CT-guided interventions. They reduce needle manipulations, procedural time, and radiation exposure, leading to fewer complications and better diagnostic success compared to freehand techniques.
Area of Science:
- Medical Imaging and Interventional Radiology
- Medical Technology and Devices
- Evidence-Based Medicine
Background:
- CT-guided interventions carry risks like radiation exposure and procedural complications.
- Navigation systems (NS) offer potential improvements in precision and efficiency for these procedures.
Purpose of the Study:
- To evaluate the impact of navigation systems (NS) versus conventional freehand techniques in CT-guided interventions.
- To compare procedural outcomes, radiation dose, and complication rates between NS and freehand methods.
Main Methods:
- A systematic review and meta-analysis of 30 studies (11 RCTs, 19 cohort studies) involving 2785 patients.
- Analysis included needle manipulations, procedural time, radiation dose, complication rates, and diagnostic/technical success.
- Random-effects models and subgroup analyses were employed, with risk of bias and certainty of evidence assessed.
Main Results:
- NS significantly reduced needle manipulations (MD, -2.58) and procedural time (MD, -8.07 min).
- Radiation dose decreased by 37% (ROM, 0.63), and overall complication rates were lower (OR, 0.64).
- Diagnostic success improved (OR, 1.66), while technical success remained comparable.
Conclusions:
- Navigation systems enhance efficiency and safety in CT-guided interventions.
- NS lead to reduced needle manipulations, radiation exposure, and complications.
- Improved diagnostic success is a key benefit of using navigation systems.
