Dose correlation with localization of AVF before catheter angiography
| Group | Fluoroscopy Time (min) | Dose of Iodinated Contrast Agent (mL) |
|---|---|---|
| A, MRA localized AVF before angiography (n = 13) | 26.3 | 146 |
| B, MRA did not localize AVF before angiography (n = 9) | 55.1 | 325 |
| C, No spinal dural AVF found despite angiography (n = 9) | 50.3 | 288 |
