Figure 2 Noncontrast computed tomography of a patient with coronavirus disease 2019 accompanied by hepatic steatosis. A: The abdominal window shows the determination of the attenuation value with the measurement of a single region of interest (an area of approximately 10 cm2) from the right liver lobe (segment 7); B: Lung window demonstrating lesions (orange arrows) compatible with coronavirus disease 2019.

Figure 3 Scatter graph showing a negative correlation between the hepatic attenuation value and pneumonia severity score measured on computed tomography (Spearman's correlation coefficient, r = −0. 357 and P < 0.001). The mean pneumonia severity score of the coronavirus disease 2019-positive group was 7.6 (4.2-11; minimum 2, maximum 18). HU: Hounsfield unit.
