Application of CT fluoroscopy to intracranial lesions

Usefulness of real-time CT fluoroscopy (CTF) as a tool for guiding intracra nial interventions was evaluated based on our clinical experience. Twenty-s ix interventional procedures were undertaken in 16 patients under CTF guide nce, which included puncture of intracranial hematoma, hematoma drainage, c erebrospinal fluid drainage and tumor biopsy. Real-time monitoring with CTF successfully demonstrated the process of intracranial interventions in all cases. The advantages of CT fluoroscopy were improved accuracy of puncture by monitoring the position and direction of the needle, and improved safet y by avoiding critical punctures.
