Volume‐Rendered 3D Display Of MR Angiograms in the Diagnosis of Cerebral Arteriovenous Malformations

Purpose:  To determine whether application of a volume‐rendered display of 3D time‐of‐flight (TOF) MR angiography could assist the diagnosis of cerebral arteriovenous malformations (AVMs). Material and Methods:  Volume‐rendered 3D images of postcontrast 3D time‐of‐flight MR angiography were compared...

Description
Summary:Purpose:  To determine whether application of a volume‐rendered display of 3D time‐of‐flight (TOF) MR angiography could assist the diagnosis of cerebral arteriovenous malformations (AVMs). Material and Methods:  Volume‐rendered 3D images of postcontrast 3D time‐of‐flight MR angiography were compared with conventional angiograms in 12 patients. The correlation between the 3D images and the operative findings was also analyzed in 5 patients. Results:  The 3D‐displayed images showed all of the feeders and drainers in 10 and 9 patients, respectively. In all patients, the nidus was three‐dimensionally visualized. In 3 patients with hematomas, the relationship between the hematoma and the AVM was well demonstrated. The 3D images corresponded well with the operative findings in the 5 patients. Conclusion:  This method is of help in assessing the relationship between the components of an AVM as well as that between an AVM and an associated hematoma.
