Case-based learning (CBL) in the context of abdominal ultrasound refers to an educational method that utilizes published clinical cases and citations to teach students how to interpret ultrasound images and diagnose abdominal conditions. This approach integrates real-world scenarios from literature, fostering critical thinking and practical application of theoretical knowledge in clinical settings. Through analyzing and discussing cited cases, students gain a deeper understanding of diagnostic principles and enhance their ability to apply ultrasound findings to patient care.
