Distribution of ΔSUVmax values in patients allocated in the class of responders and non-responders by RECIST criteria. Responders showed ΔSUVmax values significantly lower than those of non-responders (p = 0.0003, unpaired t-test) and a significant correlation was found between ΔSUVmax values and morphovolumetric response (Spearman’s rank correlation, r = 0.64, p = 0.001). Horizontal bar indicates mean
