Measurement of the UGSR value for PTMC on the right lobe of the thyroid. a and b (ultrasonic apparatus: Philips HD 11 XE): In the outpatient examination group, a longitudinal scan revealed grayscales of 50.482609 and 80.04525 for PTMC and thyroid tissues at the same gain level, respectively. The UGSR value was 0.630997 (50.482609/80.04525). c and d (ultrasonic apparatus: Siemens S2000): In the preoperative positioning group, the transverse scan showed grayscales of 50.754902 and 81.807229 for PTMC and thyroid tissues at the same gain level, respectively. The UGSR value was 0.620421 (50.754902/81.807229), and the interval was five days. The difference in the UGSR was 0.010576 (0.630997–0.620421) between the two groups (the outpatient examination and preoperative positioning groups)
