Measurement of the UGSR value for PTMC on the right lobe of the thyroid. a and b (ultrasonic apparatus: Mindray Resona7): In the outpatient examination group, a longitudinal scan revealed grayscales of 55.551108 and 85.403236 for PTMC and thyroid tissues at the same gain level, respectively. The UGSR value was 0.650457 (55.551108/85.403236). c and d (ultrasonic apparatus: MyLab Classic C): In the preoperative positioning group, a longitudinal scan showed grayscales of 55.644621 and 87.826126 for PTMC and thyroid tissues at the same gain level, respectively. The UGSR value was 0.633577 (55.644621/87.826126), and the interval was seven days. The difference of the UGSR was 0.016880 (0.650457–0.633577) between the two groups (the outpatient examination and the preoperative positioning groups)
