MDCT를 이용한 경부동맥 촬영에서 IV 선택위치에 따른 영상 비교

Image Comparision by IV route selection in Neck Angiography using MDCT -In a basis of simultaneous Angiography at Neck and Brain area-

Purpose The MDCT images in Angiography for shoulder lateral and subclavian and brachiocephalic vein always hae been resulted poor image qulities due to the high concentration of contrast medium using rapid bolus injector. Materials and Methods We sampled 413 people from January to December, 2006 who had been executed Neck-Brain Angiography who took IV routes on upper and lower extremities in C University Hospital and evaluated 100 people randomly among each of them. The program which We used for this research is CARE dose Program used as a real time dose modulation program of SIE!\1ENS Sensation 16 MIXT apparatus. Results By executing 2 examinations of both Neck-Brain Angiography at one time injection, we could give patients more economical and time saving advantages due to the reduction of contrast medium and could execute two examinations simultaneously and offer their diagnostic results faster. By the same reason -we could get both individual images of Neck Angiography and Brain Angiography and get higher diagnostic valuable images by taking IV route on lower extremities rather than upper extremities. Conclusion By executing 2 examinations of both Neck-Brain Angiography simultaneously during only one time injection of contrast medium, we could not only offer patients less exposed dose and more economical and time saving advantages, but also found that we could get higher diagnastic valuable images at the time of lower extremity IV site angiography rather than the one of upper extremity and finally that will be considered as a more useful technique in the future Angiography examinations.
