Abstract

The purpose of this paper is to evaluate the image of the Styrofoam Wedge that can minimize the position change by supporting the wrist during the True PA and lateral examination of the wrist. In 50 people, the gap between the distal radius joint facet and the wrist bone was measured after the wrist True PA and lateral images were obtained using a general examination(vertical), tube angle(vertical:10°, lateral:20°) and Styrofoam Wedge(vertical). When joint spacing was measured in the True PA and lateral images of the wrist, general examination(5.54mm, 9.42mm), tube angle(2.05mm, 5.07mm) and Styrofoam Wedge(1.79mm, 5.46mm) were shown to be small. The smaller the joint spacing, the easier it is to observe that is open. Therefore, True PA and lateral imaging of the wrist Styrofoam Wedge can reduce the distortion of the image and thus acquire images of high diagnostic value. In addition, it may be possible to reduce the deviation caused by the change of patient's position during re-projection.

본 논문은 손목 후전, 측방향 검사 시 손목을 지지하여 자세 변동을 최소화 시킬 수 있는 경사보조도구에 대해 영상 평가하고자 한다. 50명을 대상으로 일반적 검사(수직), 튜브 각도(후전방향:10°, 측방향:20°)와 경사보조도구(수직)를 이용한 손목 후전, 측방향 영상을 획득하여 먼쪽 노뼈 관절면과 손목 뼈와의 간격을 측정하였다. 손목의 후전, 측방향 영상에서 관절 간격을 측정 하였을때 일반적 검사(5.54mm, 9.42mm), 튜브 각도(2.05mm, 5.07mm) 그리고 경사보조도구(1.79mm, 5.46mm) 순으로 관절 간격이 작게 나타났다. 관절 간격이 작을수록 열려진 관찰이 용이하다. 따라서 경사보조도구를 이용한 손목의 후전, 측방향 촬영은 영상의 왜곡을 감소시켜 진단적 가치가 높은 영상을 획득할 수 있고, 재촬영 시 환자 자세 변동에 따라 발생할 수 있는 편차를 감소시킬 수 있을 것으로 사료된다.
