Multislice Analysis of Blood Flow Values in CT Perfusion Studies of Lung Cancer

Table 1

Summary of measures for slices and whole tumour referred to baseline CTp examinations: entropy (E), mean (), and median () BF values, where the subscripts and stand for slice or whole, respectively. For the whole tumour, of each slice-based measure is computed as well. Italicized and bold-italicized values point out minimum and maximum value of a given measure, respectively. Bold nonitalicized values highlight an equivalence between and , or and .
