[EN]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 OsiriXTM, 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 OsiriXTM
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.
