Clinical Sonography
Final Exam Questions
Course Introduction
Clinical Sonography is an in-depth course designed to equip students with the foundational knowledge and practical skills necessary to perform diagnostic ultrasound examinations. The curriculum covers sonographic physics and instrumentation, cross-sectional anatomy, patient care, image acquisition techniques, and interpretation of normal and pathological findings in various body systems, including abdominal, obstetric, musculoskeletal, and vascular applications. Emphasis is placed on clinical protocols, patient safety, and effective communication within the healthcare team, preparing students to function competently in diverse clinical settings and to adapt to the evolving scope of sonographic practice.
