DTI Tractography and Intratumoral Function

Tract	Positive function within tumor	P value
CST	16/56 (28.6%)	P < .001
Tract invaded	6/8 (75%)
Tract preserved	7/22 (31.8%)
Tract displaced	2/13 (15.4%)
Tract not in direct proximity with tumor	1/13 (7.7%)
AF/SLF	18/117 (15.4%)	P = .01
Tract invaded	1/7 (14.3%)
Tract preserved	12/41 (29.3%)
Tract displaced	4/37 (10.8%)
Tract not in direct proximity with tumor	1/22 (3.0)

CST = corticospinal tract, AF = arcuate fasciculus, SLF = superior longitudinal fasiculus.

Note: some patients were mapped for both language and motor function.
