RADR 2331 Upper & Lower GI Q&A 300+ Questions – GI Anatomy Barium Studies Fluoroscopy Pathology

This document provides a comprehensive collection of over 300 exam-style questions with verified answers for RADR 2331, focusing on the upper and lower gastrointestinal (GI) system, anatomy, radiographic procedures, and pathology. It is designed as a complete study guide for mastering both theoretical GI concepts and their clinical application in radiography. The material begins with foundational anatomy and physiology of the GI system, including the liver, gallbladder, esophagus, stomach, and small intestine, along with their functions and anatomical relationships (pages 1–6). For example, the liver is identified as the largest solid organ located in the RUQ and responsible for bile production, while the route of bile flow through hepatic and bile ducts into the duodenum is clearly outlined (page 2) . The document also explains digestive processes such as mastication, deglutition, peristalsis, and absorption, providing a strong physiological foundation. A major portion of the document focuses on radiographic procedures and imaging techniques, including esophagography, upper GI (UGI) studies, small bowel series, and barium enema (BE) exams (pages 4–13). It details positioning techniques such as RAO, LAO, LPO, and decubitus views, along with CR angles and imaging purposes. It also explains contrast media usage, including barium vs water-soluble iodinated contrast, single vs double contrast studies, and fluoroscopy principles for dynamic imaging. The document further includes extensive coverage of pathology identification, including esophageal varices, Barrett’s esophagus, hiatal hernia, peptic ulcers, Crohn’s disease, diverticulosis, carcinoma, and bowel obstructions (pages 11–16). It integrates clinical reasoning by linking imaging findings with disease processes, making it highly valuable for both exams and real-world application. Additionally, the content covers lower GI anatomy and function, including small and large intestine structure, absorption, elimination, and anatomical landmarks such as the ileocecal valve, haustra, and colic flexures (pages 14–15). It also includes procedural details like BE catheter insertion (Sims position), contraindications, and fluoroscopic techniques, along with advanced topics such as enteroclysis and CT colonography. The material aligns closely with standard textbooks such as Bontrager’s Textbook of Radiographic Positioning and Related Anatomy, Radiographic Imaging and Exposure by Terri L. Fauber, and Introduction to Radiologic and Imaging Sciences and Patient Care by Arlene M. Adler and Richard R. Carlton. It is particularly suitable for students enrolled in Radiologic Technology (RADR2331), Medical Imaging, and Radiography programs. This document is ideal for radiography students, medical imaging students, nursing students, and allied health learners preparing for exams, lab assessments, or registry-level examinations such as ARRT.
