| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We propose a method to detect small saccular intracranial aneurysms in three-dimensional MRA. In the proposed method, short branches were serched for after axis tinning on the vessel region. The initial candidates for aneurysm were determined in region growing from the short branches. False positives were removed with rule-based method and Support-Vector-Macnine(SVM). We applied this method to 38 dataset. The true positive rate reached 92.0%(23/25). The number of false positive were obtained 1.87 per1 case each. Our method is useful to detect small saccular intracranial aneurysms. | |
