We read with great interest the article by Daoud et al. titled "Could Spectral CT Have a Potential Benefit in Coronavirus Disease (COVID-19)?" [1].The aim of the study was to evaluate the ability of spectral CT (electron density) to enhance fine lung lesions that previously were narrowly visible on conventional CT and clearly identified on subsequently performed conventional CT in four patients with COVID-19 confirmed by reverse transcription-polymerase chain reaction (RT-PCR).The authors interestingly found that the pulmonary lesions were more noticeable on the spectral CT images than on the conventional CT images and were clearly confirmed on follow-up conventional CT.The central finding by Daoud et al. was that electron density imaging improves the early assessment of the extent of ground-glass opacities, which can be missed with conventional CT.We note the value of this study in that radiologists play an important role in the COVID-19 pandemic.It is our duty not only to be trained in this area but also to find the better technique for more accurate diagnosis to serve our patients and their treating physicians.In this case, the proposal to use spectral CT as an alternative or complementary method for radiographic identification of COVID-19 is innovative and valid.It takes into account that spectral CT improves image quality owing to increased contrast enhancement, reduced artifact, and increased tissue characterization [1,2].However, we consider the sample size a major limitation of the study.The sample is too small, considering the large number of patients who can be found who have PCR-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and have
