A New Device for Upper and Lower Extremity during CT Angiography

Purpose S표 immobilization of the patients is essential for diagnostic CT angiography. Our objective was to develop and evaluate a non-invasive device for rigid immobilization and surface disease non-contact of the 표 in the upper and lower extremity during CT angiography. Materials and Methods Patients undergoing CT examination during 8 months January to September 2004. 655 patients were evaluated with CT angiography. Upper limbs(n=41), Lower limbs(n=614) patients. Image quality in the infrapopliteal(lower limb), brachial region(upper limb). The patients upper limb device consists of a polyethylene resin which need to be immobilize is wrapped with up around the elbow joint area based vecro tape. Lower limb device stabilizing elements made of polyethylene resin soft materials, and pelvis parts foam pad is used for noncontact surface. In a prospective study the upper and lower extremity device was used in patients who underwent a CT angiography of the upper and lower limb. Results Immobilization with our device was well tolerated by all patients. The rigid immobilization resulted in a complete absence of motion artifacts. The device is well tolerated easy and quick to apply, and is now routinely used in limb angiography. During the examination the patients were explicitly asked about pain or any other discomfort, which all denied. The improvement in image quality was especially obvious in the patients who had undergone a previous CT examination without adequate immobilization. Conclusion The device immobilzation allows for comfor표, effective extremity immobilization during CT angiography resulting in complete absence of motion artifacts.
