“…However, its usefulness in joints with an unphysiological joint anatomy, such as it is the case in osteoarthritis (presence of osteophytes), is limited. In a previous study, Berliner et al showed that flat-panel detector systems can produce high quality radiographic images at a substantially reduced radiation dose in comparison with conventional computed radiography [15]. Future studies will have to evaluate the role of flat-detector guided imaging for routine interventions in terms of reduction of radiation exposure.…”

Purpose Image guidance is valuable for diagnostic injections in foot orthopaedics. Flat-detector computed tomography (FD-CT) was implemented using a C-arm, and the system was tested for needle guidance in foot joint injections. Methods FD-CT-guided joint infiltration was performed in 6 patients referred from the orthopaedic department for diagnostic foot injections. All interventions were performed utilising a flat-panel fluoroscopy system utilising specialised image guidance and planning software. Successful infiltration was defined by localisation of contrast media depot in the targeted joint. The pre-and post-interventional numeric analogue scale (NAS) pain score was assessed. Results All injections were technically successful. Contrast media deposit was documented in all targeted joints. Significant relief of symptoms was noted by all 6 participants. Conclusions FD-CT-guided joint infiltration is a feasible method for diagnostic infiltration of midfoot and hindfoot joints. The FD-CT approach may become an alternative to commonly used 2D-fluoroscopically guidance.
