Table 1. Univariate analysis of rCBV values for each group of lesions (neoplastic and infectious) and for the two subsets within the neoplastic group (primary and metastatic lesions).

Group	n	Mean ± SD	Range	p value
Infectious	46	0.63±0.49	0.3–3.5	<0.001
Neoplastic	54	4.28±2.11	0.4–9.7
Primary neoplastic	38	4.37±2.10	0.4–9.7	0.676
Metastatic	16	4.07±2.20	1.1–8.7

SD: standard deviation.
