Purpose : We aimed to evaluate the differences between true unenhanced (TUE) and virtual unenhanced (VUE) computed tomography (CT) performed by contrast-enhanced CT with dualenergy CT in the assessment of liver metastases that were difficult to visually identify with contrast- enhanced CT. Materials and methods : Between April 2018 and September 2019, we identified 266 patients with liver metastases who underwent unenhanced and contrast-enhanced CT with dual-energy CT at our institution, and enrolled 43 liver metastases in 19 patients (7.1%) that were indistinct on contrast-enhanced CT. Mean CT attenuation values for liver metastases and liver parenchyma were measured, and differences between the CT attenuation values for liver metastases and liver parenchyma were analyzed using VUE CT and TUE CT. Results : The mean CT attenuation values for liver metastases and liver parenchyma in VUE CT versus TUE CT were 51.0 vs. 41.0 HU (p |
