| Objective To establish a virtual three-dimensional cerebral aneurysm model and investigate the benefit of clinical application. Methods The virtual model including cerebral arteries and aneurysms was established by using the three-dimensional moulding software of 3D Studio MAX R3 with typical digital substraction angiography (DSA) image as the original which come from 20 cases of normal cerebral DSA image and 216 cases of cerebral aneurysms DSA images. Several doctors evaluated the similarity between virtual model and DSA image, and the value of application of clinical teaching and angiography diagnosis were evaluated. Results ① Compared with DSA image, virtual cerebral arteries possessed similarity in appearance, and had a benefit for better understanding the vascular three-dimensional spatial relationship in visual sensation. ② Compared with DSA image, virtual cerebral aneurysm could display the location of development, the direction of growth and the feature of appearance correctly. ③ The virtual model could help learner to create and increase the three-dimensional space concept of arteries and aneurysms in clinical teaching. ④ The virtual model could provide the guidance in angiography according to the simulation of the optimal showing angle of the aneurysmal shape and neck. Conclusion The virtual three-dimensional cerebral aneurysm model that was established by the software method would be useful in assisting morphology study and guiding clinical work. |
