4. 4 Experiment Assessed the effectiveness of using cross-sections in the recognition of anatomical structures in radiological images Post-test-only control group design Participants 31 freshman medical students Age range: 20-25=23; 26-above=8 Gender: 16 males; 15 females

5. 5 Experiment Types of images used in the experiment Compared the effectiveness of the following treatments on the participants’ abilities to identify anatomical structures in radiological images. Fade-in/fade-out superimposed Radiological Images with their corresponding cross-sections Fade-in/fade-out Radiological Images only Cross-sectionComputed Tomography (CT)Magnetic Resonance Imaging (MRI)
