This general radiology category forms the foundation of the question bank, geared towards physicians who wish to solidify their understanding of the fundamental principles of diagnostic imaging. The content covers cross-cutting concepts applicable to multiple systems of the human body, promoting a comprehensive understanding of radiological reasoning. The questions cover the fundamentals of interpreting radiographs, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound, addressing clinical indications, selection of the appropriate method, recognition of common errors, and clinical correlation. Emphasis is placed on the correct and systematic reading of images and the identification of normal versus pathological findings. This section is ideal for general practitioners, residents, and specialists seeking to strengthen their radiological foundation, improve their analytical skills, and optimize communication with diagnostic imaging services. The question bank is designed to stimulate critical thinking and enhance image-based clinical decision-making.
