Skull X-ray (Suture Separation/Enlarged Sella/ICT) MCQ Quiz | Radiology

Welcome to the Radiology quiz on Skull X-rays, specifically focusing on the interpretation of suture separation, an enlarged sella turcica, and signs of increased intracranial tension (ICT). This quiz is tailored for MBBS students to test and reinforce their understanding of these critical neuroradiological findings. Each of the 25 questions is designed to challenge your knowledge of pathologies, their radiographic appearances, and differential diagnoses. After submitting your answers, you will receive your score and a detailed review of each question. You can also download a PDF of all questions with their correct answers for your future reference and study. Good luck, and may your diagnostic skills be sharp!
