Percutaneous abdominal and pelvic interventional procedures using CT fluoroscopy guidance

Area of Science:

• Radiology
• Interventional Radiology
• Medical Imaging

Background:

• Percutaneous abdominopelvic procedures require precise guidance for safety and efficacy.
• Traditional imaging guidance methods may have limitations in real-time visualization.

Purpose of the Study:

• To evaluate the utility of low-milliamperage computed tomography (CT) fluoroscopy for guiding percutaneous abdominopelvic interventions.
• To assess the feasibility and effectiveness of this technique in various procedures.

Main Methods:

• Retrospective review of 97 patients undergoing 119 procedures guided by low-milliamperage CT fluoroscopy.
• Procedures included fluid aspiration/drainage, biopsy, ablation, chemoneurolysis, and brachytherapy catheter insertion.
• Real-time fluoroscopy reconstruction at six frames per second enabled direct operator control.

Main Results:

• 94.1% of procedures were successfully completed with adequate image quality for device placement.
• CT fluoroscopy facilitated rapid assessment of instrument positioning, especially in nonaxial planes.
• Average CT fluoroscopy times were 133 seconds for biopsies and 186 seconds for therapeutic procedures.

Conclusions:

• Low-milliamperage CT fluoroscopy is a practical and effective tool for percutaneous abdominal and pelvic interventional procedures.
• The technique supports accurate guidance for biopsies, drainage, and therapeutic interventions.
