<h3>BACKGROUND AND PURPOSE:</h3> MRI is routinely performed following brain AVM after treatment in children. Our aim was to determine the predictive values of contrast-enhanced MR imaging and TOF-MRA for recurrence children, compared with conventional angiography role 3D rotational angiography–MR fusion these cases. <h3>MATERIALS METHODS:</h3> We included all pediatric patients AVMs during an 18-year period angiographically documented obliteration treatment. Patients underwent 3T imaging, including TOF-MRA, angiography, a subset undergoing angiography. The were determined. CTA sections reconstructed from coregistered fused 3D-T1WI analysis. <h3>RESULTS:</h3> Thirty-nine children (10.8 ± 3.9 years age; range, 2–17 years; male/female ratio, 19:20; mean Spetzler-Martin grade, 1.9 0.6) met inclusion criteria. Of these, 13 had confirmed recurrence, 8 surgery 5 embolization. Sensitivity, specificity, positive negative following: imaging: 84.6%, 38.5%, 40.7%, 81.8%; TOF-MRA: 50.0%, 96.1%, 85.7%, 79.3%; both: 75.0%, 90.9%, 83.3%. images or excluded available cases (13/13). Embolization-only significant predictor (OR = 32.4, <i>P</i> .006). features tuft vessels on nodular juxtamural/linear enhancement draining vein imaging. <h3>CONCLUSIONS:</h3> useful surveillance but required definitive diagnosis recurrence. provide complementary information determining should be interpreted conjunction. increases diagnostic confidence regarding therefore suited intraoperative neuronavigation.
