Fig. 8From: Influence of cellular models and individual factor in the biological response to head CT scan examspATM foci in astrocytes after single and double-helical CT-scan exposure. a Kinetics of pATM foci in astrocytes after a single helical head CT scan, or (b) a double-helical head CT scan at the indicated times after exposure (t0 = non-irradiated). Each data represents the mean ± SEM foci per cell of three independent experiments. Asterisks for time 10 min correspond to a statistically significant difference between HA-h and the other cell lines.
