Subgroup comparison of paragangliomas with prior radiation treatment (n = 9) and with no radiation treatment (n = 13) using normalized semiquantitative perfusion metricsa
| AUC | Peak | TME | Wash-in | Washout | |
|---|---|---|---|---|---|
| Para-RT | 0.80 (SD, 0.15) | 0.84 (SD, 0.19) | 1.04 (SD, 0.33) | 0.96 (SD, 0.12) | 1.00 (SD, 0.16) |
| Para-NT | 0.90 (SD, 0.2) | 0.87 (SD, 0.22) | 1.04 (SD, 0.17) | 1.03 (SD, 0.12) | 1.01 (SD, 0.14) |
| P value | .22 | .68 | .97 | .20 | .86 |
Note:—NT indicates no radiation treatment; RT, radiation treatment, Para, paraganglioma.
↵a There was no statistical difference between these subcategories of paragangliomas in terms of semiquantitative perfusion parameters. Data are means unless otherwise indicated.
