These medical illustrations depict two common image-guided biopsy procedures used to diagnose the nature of mediastinal masses. These illustrations were part of a scientific exhibit discussing the details, techniques, and pitfalls using axial (CT), ultrasound, and endoscopic ultrasound to enable safe access to the lesion, avoidance of vasculature, minimizing risk of pneumothorax, and obtaining adequate lesion samples. These illustrations serve as educational an eye-catching imagery used on the RSNA poster exhibit, as well as a dynamic full-page color image accompanying the radiological journal publication. The primary focus is the education of Radiologists, Oncologists, and Ultrasound Technicians associated with these and other related procedures.
