Bowel obstruction: comparison between multidetector-row CT axial and coronal planes.
Acute obstruction of bowel is a common reason for presentation to the emergency department. Causes of obstruction are multiple (tumorous, inflammatory, postoperative, or congenital), but the clinical presentation is usually not specific. The abdominal radiographs are sometimes inconclusive, and cause of obstruction is rarely detected. Computed tomography (CT) has been shown to be useful in revealing the site and the cause of obstruction. Although radiologists are skilled in the interpretation of CT scans in the axial plane, the development of multidetector-row CT coupled with fast reconstruction hardware and software has stimulated interest in viewing abdomen in coronal plane. In the evaluation of small bowel obstruction, coronal plane serves as a useful adjunct for the identification of the point of transition from dilated to decompressed bowel. On the other hand, in the evaluation of large bowel obstruction, coronal planes could replace axial images in the evaluation of the site and cause of obstruction, although the best values of confidence level in the diagnosis are reached when interpreting axial combined with coronal images.
