AI assistance strategy
Two months after the first reading, the doctors read the 812 ultrasonic images again (second reading) with a concurrent reading mode. This meant that, for each image, there would be two images (image without and with an AI diagnosis) shown on the screen side-by-side, and the doctors would read these two images and make a diagnosis. The diagnostic performance and time of the first and second readings were compared to evaluate the capability of AI in assisting diagnosis.
