减少或不进行肠道导泻以及粪便标记的计算机断层扫描结肠成像 (CTC) 已出现，以提高患者对 CTC 的耐受性及其随后对结直肠癌筛查的依从性。通过粪便标记，电子清洁是通过后处理软件进行的，该软件可以去除残留的对比材料。然而，由于该技术是基于阈值的，因此可能会注意到降低图像质量和检查准确性的伪影。基于双能 CT 和特定材料清洁的光谱电子清洁可减少伪影数量并提高图像质量。在这篇综述中，我们描述了减少宣泄 CTC 的光谱净化，并说明了其潜在的好处。 Semin 超声 CT MRI 31:309-314 (C) 2010 Elsevier Inc. 保留所有权利。
Computed tomography colonography (CTC) with reduced or without bowel catharsis and with fecal tagging has emerged to improve CTC tolerability in patients and their subsequent compliance with colorectal cancer screening. With fecal tagging, electronic cleansing is performed by postprocessing software that removes remnants of contrast material. However, because the technique is threshold based, artifacts that lower the image quality and accuracy of the examination may be noted. Spectral electronic cleansing, based on dual-energy CT and on material-specific cleansing, decreases the number of artifacts and improves image quality. In this review we describe spectral cleansing with reduced catharsis CTC and illustrate its potential benefits. Semin Ultrasound CT MRI 31:309-314 (C) 2010 Elsevier Inc. All rights reserved.
