Abstract:
Objective: To explore the value of 4D-CTA based on computed tomography dynamic angiography for preoperative evaluation of meningioma. Methods: Totally 34 patients with intracranial meningioma underwent cranial dynamic volume CT scan. Then 3D-CTA and 4D-CTA related post-processing were performed. The difference of tumor size, tumor feeding artery and the relationship of tumor and skull, passing artery and peripheral venous system showed with 3D-CTA and 4D-CTA were compared. Results: There was no significant difference between 3D-CTA and 4D-CTA in evaluating tumor size and tumor feeding artery (both P> 0.05). The percentage of definite draining veins evaluated with 3D-CTA was 70.59% (24/34), lower than that with 4D-CTA (94.12% [32/34], P< 0.05). The accuracy of 3D-CTA and 4D-CTA for evaluating the relationship between tumor and skull was 91.18% (31/34) and 97.06% (33/34), and the accuracy of for evaluating the relationship between tumor and passing artery was 87.50% (21/24) and 95.83% (23/24), respectively (both P> 0.05). Conclusion: CT dynamic angiography can accurately evaluate the size of meningioma, the feeding artery and relationship with surrounding tissue, therefore providing comprehensive preoperative information of meningioma.
