Rater comparisons by specialty^a

	Neuroradiologist	Nonradiologist	P Value
Distance from foot motor centroid	15 ± 8 mm	20 ± 14 mm	.005b
Arrow in motor gyrus	61% (206/336)	46% (71/154)	.008b
Tumor in foot motor cortex	78% (261/336)	74% (114/154)	.515
Tumor in motor gyrus	72% (242/336)	69% (106/154)	.569

^aNumbers in the parentheses indicate the number of correct responses over the total number of responses (eg, in the neuroradiologist group, there were 24 raters for each of the 14 cases, making 336 total responses).

^bSignificant (P ≤ .05).
