Background. Medical images have passed from static and printed images with no possibility of modifying many technical parameters to volumetric data that allow its manipulation and advanced processing for surgical or pedagogical purposes. Aim. The aim of this paper is to demonstrate the major role and potential of OsiriX™, a new open-source computerized tool for the advanced processing of medical images, in the study of neurovascular anatomy. Methodology. DICOM images were acquired with radio diagnostic equipment using 1.5 Tesla Magnetic Resonance (MR) images from a 34-year-old and right-handed female. Images were further processed using OsiriX™ version 4.0 32 bits for OS, one of the most versatile technologies within the field of medical imaging. Results. Key features required for processing neurovascular images such as segmentation and three-dimensional reconstruction of vascular elements (cerebral arteries and Willis polygon) are visually illustrated and described. Conclusion. The application of this technology in medical imaging has enhanced the accessibility and availability of neuroimaging, reducing the need for sophisticated and expensive workstations for image processing. Advanced image processing allows overcoming limitations inherent to classical techniques based on two-dimensional sections. Three-dimensional reconstructions of vascular elements are already used in daily clinical practice, including diagnostic protocols. Also, interactivity and virtual visualization makes it simple, cost-effective and easy to understand complex vascular elements. Discussion. Implications for teaching and learning neurovascular concepts and diagnostic value are discussed.
