 A Corrigendum on Diagnostic Accuracy of Delayed Phase Post Contrast Computed Tomographic Images in the Diagnosis of Focal Liver Lesions in Dogs: 69 Cases by Burti, S., Zotti, A., Bonsembiante, F., Contiero, B., and Banzato, T. (2021). Front. Vet. Sci. 8:611556. doi: 10.3389/fvets.2021.611556 decision tree HCC (hepatic cellular carcinoma) contrast - enhanced CT computed tomography focal liver lesion

In the original article an error occurred with the ellipsoid volume formula and subsequently there were errors in Table 2. The volume was calculated using formula V = 4/3*(height*width*length) whereas the correct formula is: V = 4/3*(height/2*width/2*length/2). Therefore, the results reported in Table 2 are 8 times bigger than the actual volume. The corrected Table 2 appears below.

Quantitative features of the lesions, classified based on cytological or histological examination, are reported as medians along with the first and third quartile values and the p-value.
