Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to examine the feasibility of distinctly visualizing the different cervical venous networks (subcutaneous, muscular, extra-canalicular, and intra-canalicular) using dedicated magnetic resonance imaging (MRI) sequences. Theoretically, these venous networks contribute to the complex distribution of blood drainage in the cervical region, but their precise identification on imaging remains challenging.The objectives of this research are twofold: first, to assess the ability of MRI to differentiate each venous network, thereby enhancing the anatomical and functional understanding of this region; and second, to explore the possibility of grouping patients according to the predominant venous network, which could reveal significant physiological variations and specific anatomical profiles.The results could not only refine the diagnosis of cervical vascular pathologies but also guide targeted therapeutic approaches.
