	IAT-Group	Non-IAT Group	P Value
Total No. of enhancing foci	21.5	30	.04^{^a}
Total No. of ipsilateral enhancing foci	18.5	18.0	.003^{^a}
Total No. of contralateral enhancing foci	3.0	12.0	.74^{^a}
Total No. of concentric ipsilateral foci	9.0	8.5	.02^{^a}
Total No. of eccentric ipsilateral foci	9.5	9.5	.07^{^a}
Total No. of enhancing foci ipsilateral vs contralateral (proportion) P value	(18.5 vs 3.0) .005^{^b}	(18.0 vs 12.0) .47^{^b}
Total No. of concentric enhancing foci ipsilateral vs. contralateral (proportion) P value	(9.0 vs 0.0) .011^{^b}	(8.5 vs 3.0) .14^{^b}
Total No. of eccentric enhancing foci ipsilateral vs. contralateral (proportion) P value	(9.5 vs 3.0) 06^{^b}	(9.5 vs 9.0) .97^{^b}
