Abstract:
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.
