The present update to both documents incorporates a multidisciplinary approach to the periprocedural management of coagulation status with emphasis on the patient's clinically relevant comorbidities, and will be divided into 2 parts: part I will review classes of anticoagulation medications and clinical considerations common to patients requiring percutaneous image-guided interventions; part II will discuss recommendations. METHODOLOGYThe Standards Division of SIR provides evidence-based clinical practice documents to ensure patient safety and enhance the delivery of patient care. Standards Division members are leaders in the field of interventional radiology from the private and academic sectors of medicine who dedicate the vast majority of their professional time to performing interventional

Much of radiology education has currently focused on the concept of spoon-feeding information from the teacher to the learners. This article outlines the dangers of this approach in radiology and offers solutions for educators to improve their teaching skills and use the potential afforded by the diversity of the field.
