Hybrid Procedure Suites: Combining Computed Tomography and Conventional Angiography.

Abstract

The effectiveness of a combined computed tomography and angiography system in interventional radiology was evaluated based on imaging information required at each step. During the planning phase, three-dimensional visualisation of the target and surrounding organs is essential, making computed tomography superior to X-ray fluoroscopy and ultrasound. Real-time imaging with high spatial resolution is crucial for target access; however, X-ray fluoroscopy, ultrasound, and computed tomography alone cannot fully meet these requirements. When manipulating interventional radiology devices, high spatial resolution and real-time capabilities are essential, making X-ray fluoroscopy the preferred modality. To confirm the outcome of the procedure, three-dimensional imaging without hidden areas is necessary with computed tomography being the most suitable option. In conclusion, although no single imaging modality is ideal for all steps of interventional radiology, considering the mobility of US, angiography-computed tomography system, which integrates angiography and CT on a single table, is useful for accurately carrying out various treatments in interventional radiology.
