This study was performed to assess low-dose scan parameters in dual-energy computed tomography (CT) for displaying the anterior cruciate ligament.
Dual-energy CT scans with low and standard dose parameters, respectively, were performed in nine human knee joint specimens. Eighteen imaging data sets for cruciate ligament specimens were obtained and processed. Statistical analysis was performed for signal-to-noise ratios of the CT images and subjective scores.
Comparable signal-to-noise ratios and subjective image quality scores by evaluators in dual-energy CT anterior cruciate ligament images between the low and standard-dose groups were observed.
Low-dose scan parameters do not compromise the outcomes of anterior cruciate ligament imaging.
本研究旨在评估双能计算机断层扫描（CT）中用于显示前交叉韧带的低剂量扫描参数。
分别对九个膝关节标本进行低剂量和标准剂量参数的双能CT扫描。获得并处理了18组交叉韧带标本的成像数据集。对CT图像的信噪比和主观评分进行了统计分析。
观察到低剂量组和标准剂量组的双能CT前交叉韧带图像中，评估者给出的信噪比和主观图像质量评分具有可比性。
低剂量扫描参数不会影响前交叉韧带成像的效果。
