Peripheral Venous Access Management by Radiologic Technologists in Radiodiagnostic Procedure

The goal of this interventional study is to evaluate the impact of a structured training program on the ability of Radiologic Technologists (RTs) to safely and effectively perform peripheral venous access (PVA) placement for contrast media administration in a radiodiagnostic setting. The study focuses on adult patients undergoing contrast-enhanced imaging procedures and on Radiologic Technologists who have completed a competency-based theoretical and practical training program on peripheral venous access management. The main questions it aims to answer are: * Does a structured training program improve the theoretical knowledge and technical competencies of Radiologic Technologists in peripheral venous access placement? * What is the incidence of complications associated with peripheral venous access placement performed by trained Radiologic Technologists in routine clinical practice? * How do patients perceive the procedure in terms of pain, safety, procedural success, and overall satisfaction? Participants: * Radiologic Technologists will participate in a structured theoretical and practical training program focused on peripheral venous access placement for contrast media administration. * Radiologic Technologists will perform peripheral venous access placement during routine radiodiagnostic procedures following completion of the training. * Patients undergoing contrast-enhanced imaging will receive peripheral venous access placement performed by trained Radiologic Technologists and will complete questionnaires assessing pain, satisfaction, and perceived safety of the procedure.
