Abstract
Small bowel obstruction is a relatively common clinical condition and its diagnosis is based on the clinical signs, the patient’s history and the radiologic findings. For a patient with suspected small bowel obstruction, it is essential to determine the site, location and cause of obstruction for the appropriate management. Because of the poor accuracy of plain radiography, computed tomography (CT) now has an essential role to diagnose bowel obstruction. With the recent evolution of conventional CT into multidetector computed tomography (MDCT), it is possible to obtain cross sectional images with high spatial resolution and different post-processes can be done, such as obtaining the volume rendering (VR), maximum intensity projection (MIP), or multiplanar reformatted (MPR) images from the volume data. In this article, we illustrate and discuss the utility of the multiplanar images of MDCT for diagnosing the sites, causes and complications of small bowel obstruction.
소장폐쇄는 임상에서 흔히 접하며 그 진단은 임상증상과 환자의 과거력, 영상의학 소견을 종합하여 내리게 된다. 소장폐쇄가 의심되는 환자에서 폐쇄부위와 원인결정은 적절한 치료의 기본이다. 영상검사로 복부단순촬영을 흔히 시행하지만 그 정확도가 낮아 복부전산화단층촬영(CT)을 소장폐쇄의 진단에 필수검사로 시행하고 있다. 최근 다중검출기전산화단층촬영기(MDCT)가 많이 보급되어 고해상도의 단면영상을 얻을 수 있고 삼차원영상프로그램을 통한 영상의 다면재구성이 가능해졌다. 이 종설에서는 소장폐쇄의 원인, 부위, 및 이들과 동반된 합병증진단에 MDCT검사와 다양한 삼차원재구성영상의 유용성을 기술하고자 한다.
