Summary
Computed tomography (CT) fluoroscopy is a versatile tool for interventional procedures. Employing lead drapes and radiation protection gloves significantly reduces radiologist radiation exposure during CT fluoroscopy.
Area of Science:
- Radiology
- Medical Imaging
- Interventional Procedures
Context:
- CT fluoroscopy is increasingly utilized for guiding diagnostic and therapeutic interventions.
- A comprehensive analysis of its application over one year was conducted.
Purpose:
- To evaluate the techniques, indications, and radiation exposures associated with CT fluoroscopy.
- To assess the effectiveness of protective measures in reducing scatter radiation.
Summary:
- CT fluoroscopy supports a broad range of procedures, from biopsies to radiofrequency ablation and osteosynthesis.
- Radiologist hand radiation exposure varied widely (1-320 microSv/case) without protective gear.
- A lead drape reduced exposure by 72%, gloves by 49%, and the combination by 97%.
Impact:
- CT fluoroscopy is a valuable targeting method for diverse interventional procedures.
- Awareness of techniques and protective measures is crucial for minimizing radiologist radiation exposure.
- Implementation of lead drapes and radiation protection gloves is highly effective in dose reduction.
