The field of vascular interventional radiology has witnessed remarkable advancements, transforming the landscape of patient care for both vascular and non-vascular pathologies. Through minimally invasive techniques, we can now offer therapeutic alternatives with reduced complications to patients who are not eligible for conventional treatments. With the emergence of personalized therapies tailored to specific pathologies, disease stages, and patient characteristics, we find ourselves at the forefront of a new era in medicine where treatments are uniquely tailored to each individual. This Special Issue of the Journal of Personalized Medicine features a comprehensive collection of 16 articles, primarily focusing on embolization, a major theme in vascular interventional radiology. Embolization techniques have revolutionized the field, providing effective treatment options for various conditions. Within this issue, we delve into various aspects of embolization, including the embolization of the prostatic artery, splenic trauma, polycystic liver disease, soft tissue hematomas, pulmonary arteriovenous malformation, gastrointestinal bleeding, and even emerging themes such as musculoskeletal embolization. These articles showcase the breadth and depth of research in the field, offering insights into the latest advancements and personalized approaches in embolization therapies.
