OBJECTIVE
To compare lesion conspicuity amongst DECT monochromatic series (40, 45, 50keV), and single-energy CT (SECT) equivalent images in head and neck squamous cell carcinomas (HNSCC).
METHODS
Two readers compared DECT images to 70keV SECT equivalent series in 39 patients with HNSCC on lesion margin, enhancement, and overall conspicuity.
RESULTS
The 45keV and 50keV images were significantly better (p-values ≤0.001) than the SECT equivalent in lesion enhancement, margins, and overall conspicuity for both readers. Readers mostly preferred the 50keV monochromatic series.
CONCLUSION
DECT can provide better lesion visualization than SECT in HNSCC.
目的
比较双能CT（DECT）单色系列（40、45、50keV）与单能CT（SECT）等效图像在头颈部鳞状细胞癌（HNSCC）中的病灶显示清晰度。
方法
两名阅片者将39例HNSCC患者的DECT图像与70keV SECT等效系列图像在病灶边缘、强化及整体显示清晰度方面进行比较。
结果
对于两名阅片者而言，45keV和50keV图像在病灶强化、边缘及整体显示清晰度方面均显著优于SECT等效图像（p值≤0.001）。阅片者大多更倾向于50keV单色系列。
结论
在HNSCC中，DECT比SECT能提供更好的病灶可视化效果。
