We describe a case of small bowel Crohn's disease in which dual-energy computed tomography enterography using dual-layer spectral detector scanner contributed to quantitative assessment, and provided a higher degree of confidence pertaining to the diagnosis. Dual-layer spectral detector computed tomography enables retrospective analysis including virtual monochromatic imaging, iodine mapping, and determining the effective atomic number Z with routine scan protocols. These advanced parametric dual-energy imaging holds promising potential as an imaging biomarker for diagnosis, risk-stratification, monitoring of disease progression and therapy, and outcome prediction.
我们描述了一例小肠克罗恩病，其中使用双层光谱探测器扫描仪的双能计算机断层扫描小肠造影有助于定量评估，并为诊断提供了更高的可信度。双层光谱探测器计算机断层扫描能够进行回顾性分析，包括虚拟单色成像、碘图绘制以及使用常规扫描协议确定有效原子序数Z。这些先进的参数化双能成像作为一种成像生物标志物，在疾病诊断、风险分层、疾病进展和治疗监测以及结果预测方面具有广阔的应用前景。
