Rickets & Scurvy – Radiology MCQ Quiz | Radiology

Welcome to the Radiology quiz on Rickets and Scurvy, specifically designed for MBBS students. This quiz will test your knowledge of the key radiological findings that distinguish these two important metabolic bone diseases. You will encounter questions on classic signs such as metaphyseal fraying, the white line of Fraenkel, subperiosteal hemorrhages, and Looser’s zones. Understanding these radiographic features is crucial for accurate diagnosis and management. This assessment consists of 25 multiple-choice questions. After submitting your answers, you’ll see your score and a detailed review of each question. For your revision, you can download all the questions along with their correct answers in a convenient PDF format. Good luck!
