Abstract
In this anthropomorphic head phantom study, samples containing blood and contrast agent with concentrations ranging from 0 to 6 mg iodine per milliliter and another set of samples without blood for reference were scanned with a photon-counting detector CT using a standard cranial protocol. It was demonstrated that photon-counting detector CT can reliably distinguish hemorrhage and contrast media, including density determination of the latter. The technology promises to add value in several neuroimaging applications.
摘要
在这项拟人化头部体模研究中，使用标准颅脑扫描协议，通过光子计数探测器CT对含有浓度范围为0至6毫克碘每毫升的血液和造影剂的样本以及另一组不含血液的参考样本进行了扫描。结果表明，光子计数探测器CT能够可靠地区分出血和造影剂，包括对后者的密度测定。这项技术有望在多种神经成像应用中发挥价值。
