High-precision, patient-specific 3D models of brain aneurysms for therapy planning and training in interventional neuroradiology

Endovascular treatment of complex intracranial aneurysms is challenging because the configuration of each aneurysm is unique. Using 3D printing, the individual anatomy of the aneurysm can be reproduced with high precision, allowing a deep understanding of the diseased vessel. Here we present a method for the high-resolution and patient-specific production of 3D models of brain aneurysms using stereolithography 3D printing techniques.
