title: Non-vascular intervention with real-time CT fluoroscopy.
abstract: The emerging technology of CT fluoroscopy (CTF) represents the first opportunity for real-time CT guidance in non-vascular intervention. As with any new technology, its efficacy requires validation before widespread application can be advocated. A review of our initial experience is presented with particular attention to room, procedure and fluoroscopy time savings, complication rates and dosimetry. Computed tomography fluoroscopy is useful for pulmonary, pelvic, retroperitoneal and other deep organ lesions that are not easily accessible by other modalities. Computed tomography fluoroscopy decreases procedure time by at least a factor of 2 compared with conventional CT (C-CT) guidance, resulting in improved throughput in a busy interventional CT department. Accurate targeting of small lesions, previously considered inaccessible, can also be achieved with CTF. Exposure to the physician's hands can be reduced to a level that is acceptable to the International Commission on Radiological Protection guidelines.
