One-way ANOVA variance test for MTR values in corresponding groups
| Groups | Number of cases | the lesion parenchymal areas | the edema areas | the non focal areas | ||
|---|---|---|---|---|---|---|
| MTR’s Mean ± standard deviation(%) | F value | P value | ||||
| A | 20 | 1.07 ± 0.22 | 1.04 ± 0.23 | 1.06 ± 0.24 | 0.074 | 0.929 |

| C | 15 | 6.29 ± 1.58 | 2.87 ± 0.65 | 1.03 ± 0.30 | 99.167 | 0.000 |
| F value | 98.741 | 87.420 | 4.160 | |||
| P value | 0.000 | 0.000 | 0.002 | |||
P < 0.05, there is a statistical difference
A: normal group; B: metastatic tumor group; C: glioma group
