Table 2 Summary of tumor perfusion patterns in patients

Perfusion type	Before treatment	1 month after treatment	3 months after treatment	6 months after treatment	F value	P value
Enhanced (normal perfusion)	68.25 ± 6.23	62.75 ± 5.99	58.50 ± 5.13	53.75 ± 5.28	4.378	0.03
Uniform (low perfusion)	21.50 ± 4.56	26.50 ± 4.72	28.00 ± 4.50	31.25 ± 4.89	5.187	0.022
Non-uniform (low perfusion)	10.25 ± 3.79	10.75 ± 4.12	13.50 ± 4.12	15.00 ± 3.89	6.123	0.016
Total perfusion rate	68.25 ± 6.23	62.75 ± 5.99	58.50 ± 5.13	53.75 ± 5.28	4.378	0.03

P < 0.05 indicates a significant difference.
