Objective To evaluate the application of 3.0T TOF magnetic resonance angiography (MRA) in intracranial aneurysm coiling follow-up retrospectively.Methods In our hospital,48 patients who underwent intracranial aneurysm coiling were followed up for one to two years with radiologic examination,which inclouded 3.0T TOF-MRA and Digital subtraction angiography(DSA) examination.DSA served as the golden standard.The MRA image quality and the results were compared.Results 3.0T TOF-MRA to determine aneurysm recurrence sensitivity was 85.7％,specificity was 95.7％,total accuracy rate was 93.8％,and the accuracy of the patency of the parent arterial was 93.8％.There was no significant difference between the 3.0T TOF-MRA and DSA (P ＞ 0.05).Conclusion In the patients after coiling,3.0T TOF-MRA in the judgment of the aneurysm embolization results and the patency of the parent artery had a high degree of consistency compare with DSA.We can use 3.0T TOF-MRA as a routine means in the follow-up.We should analysis individually for positive results and uncertainties.By optimizing imaging and scanning parameters might obtain better images.Perform DSA if necessary,when MRA was positive or uncertainty.
