Characterization of Enhancing MS Lesions by Dynamic Texture Parameter Analysis of Dynamic Susceptibility Perfusion Imaging

Table 2

One-way ANOVA of the texture parameter maps (TPMs): number of significant differences in the different time periods. A total of 19 out of 48 (12 4) tests revealed statistical significant differences.

	IF	OF	RP	Total
TPM-ORIG	0	0	2	2
TPM-DIFF	1	2	4	7
TPM-SD	0	1	4	5
TPM-VAR	0	2	3	5
Total	1	5	13	19

Note: ORIG: raw image, DIFF: difference image, SD: standard deviation, VAR: local variance, IF: inflow, OF: outflow, and RP: reperfusion.
