Purpose: To assess the significance of three-dimensional CT-angiography (3D-CTA) in detecting remnant necks after cerebral aneurysm clipping, 3D-CTA was compared with intra-arterial digital subtraction angiography (IADSA). Materials and Methods: Fifty-nine patients (79 aneurysms) underwent both IADSA and 3D-CTA after cerebral aneurysm clipping. A single detector spiral scanner was used for 3D-CTA. Shaded surface display (SSD) and volume rendered (VR) images were produced from each data set. Two blinded observers independently evaluated the presence of remnant necks on SSD images, VR images and IADSA. Results jointly evaluated by three observers were applied as the gold standard to assess diagnostic accuracy of each image. Diagnostic performance of each image was evaluated using receiver operating characteristic (ROC) analysis. Results: Mean sensitivity and specificity of SSD images for detecting remnant necks were 50.0% and 74.2%, respectively. VR images displayed a mean sensitivity and specificity of 63.3% and 82.8%, respectively. IADSA demonstrated a mean sensitivity and specificity of 93.3% and 92.2%, respectively. Under ROC analysis, IADSA displayed excellent diagnostic performance (mean Az [area under ROC curve] =0.97). While 3D-CTA demonstrated good diagnostic performance (0.68 and 0.76 for SSD and VR, respectively), it was significantly inferior to IADSA (P <.001). Mean Az for VR imaging was significantly superior to that for SSD imaging (P <.001) . Conclusion: Following clipping surgery for cerebral aneurysms, 3D-CTA, and particularly VR imaging, is useful for postoperative evaluation. As a noninvasive alternative, 3D-CTA could be recommended for routine use. However, IADSA should still be performed when 3D-CTA yields uncertain results. |
