We describe a case of ischemia complicating acute small-bowel obstruction in which retrospective on-demand spectral analysis using dual-layer spectral detector computed tomography (CT) provided a higher degree of confidence pertaining to the diagnosis. Dual-layer spectral detector CT enables retrospective on-demand spectral analysis, including virtual monochromatic imaging, iodine mapping, and determining the effective atomic number Z, without the need of a pre-scan setting requiring a special protocol, particularly facilitating emergency situations. Retrospective on-demand spectral analysis could improve the accuracy and diagnostic confidence in cases with ischemia complicating small-bowel obstruction.
我们描述了一例急性小肠梗阻并发缺血的病例，其中使用双层光谱探测器计算机断层扫描（CT）进行回顾性按需光谱分析，对诊断具有更高的可信度。双层光谱探测器CT能够进行回顾性按需光谱分析，包括虚拟单色成像、碘图绘制以及确定有效原子序数Z，而无需进行需要特殊协议的预扫描设置，特别有利于紧急情况。回顾性按需光谱分析可以提高小肠梗阻并发缺血病例的准确性和诊断可信度。
