Summary
Real-time CT fluoroscopy enhances diagnostic and therapeutic procedures, improving sensitivity for neoplastic lesions and procedure safety. This technique offers economic benefits through reduced procedure times and increased outpatient accessibility.
Area of Science:
- Medical Imaging
- Interventional Radiology
Background:
- Advancements in CT technology and computer hardware enable ultrafast image acquisition and reconstruction.
- CT-guided procedures are increasingly utilized for diagnosis and therapy.
Purpose of the Study:
- To evaluate the efficacy and safety of real-time CT fluoroscopy-guided interventions.
- To compare current techniques and outcomes with existing literature.
Main Methods:
- Analysis of 337 intervention procedures performed over 17 months.
- Comparison of sensitivity, complication rates, procedure time, and outpatient scope with literature data.
Main Results:
- Improved sensitivity for neoplastic lesions, particularly intrapulmonary ones (94%).
- High safety profile with only one major complication across all procedures.
- Reduced average 'in-room' procedure time to under 30 minutes.
- Successful execution of complex interventions including drainage, drug injection, ablation, and biopsy.
Conclusions:
- Real-time CT fluoroscopy significantly broadens the clinical indications for CT-guided procedures.
- The technique offers enhanced sensitivity, safety, efficiency, and patient comfort.
- Potential concerns regarding radiation exposure can be mitigated with appropriate techniques and tools.
