Quantitative Analysis of Diffusion Weighted MR Images of Brain Tumor Using Signal Intensity Gradient Technique

Table 1

Decisive SIG and Mean RSIG values for subjects with glioma and meningioma.

Tumor type	Number of cases	Decisive SIG values (𝑥±𝑠)		Mean RSIG values (𝑥±𝑠)
		Tumor side	Contralateral side
Glioma	20	156.75±71.42	9.17±4.33	16.87±4.69
Meningioma	12	114.05±51.41	13.22±6.67	7.94±1.54

∗(𝑥±𝑠) = (mean ± standard deviation).
