Summary
Computed tomographic (CT) fluoroscopy (CTF) significantly reduces procedure time for CT-guided biopsies compared to traditional methods. While success rates showed a slight, non-significant increase with CTF, the efficiency gains are substantial.
Area of Science:
- Radiology
- Medical Imaging
- Interventional Procedures
Background:
- CT-guided biopsies are crucial for tissue diagnosis.
- Traditional CT-guided biopsies can be time-consuming.
- Advancements in imaging technology aim to improve procedural efficiency.
Purpose of the Study:
- To evaluate the clinical impact of computed tomographic (CT) fluoroscopy (CTF) on CT-guided biopsy procedures.
- To compare procedure time and success rates between CTF and conventional CT-guided biopsies.
Main Methods:
- Prospective study of 190 patients undergoing CTF-guided biopsies.
- Retrospective analysis of 93 patients undergoing conventional CT-guided biopsies.
- Comparison of total procedure time, fluoroscopy time, complication rates, and success rates.
Main Results:
- CT fluoroscopy (CTF) significantly reduced mean procedure time (27.56 minutes) compared to conventional CT guidance (43.17 minutes; P < .0001).
- Procedure success rate was higher in the CTF group (93.7%) versus the control group (88.2%), though not statistically significant (P > .05).
Conclusions:
- CT fluoroscopy enhances CT-guided biopsy procedures by enabling real-time needle visualization.
- CTF allows for more rapid and efficient performance of CT-guided biopsies.
- The technology shows promise for improving workflow in interventional radiology.
