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.
