Measurement of the UGSR value for MNG on the left lobe of the thyroid. a and b (ultrasonic apparatus: Mindray Resona7): In the outpatient examination group, a longitudinal scan revealed grayscales of 54.667273 and 63.817095 for MNG and thyroid tissues at the same gain level, respectively. The UGSR value was 0.856624 (54.667273/63.817095). c and d (ultrasonic apparatus: Esaote Mylab 90): In the preoperative positioning group, a longitudinal scan shows grayscales of 77.587572 and 88.556865 for MNG and thyroid tissues at the same gain level, respectively. The UGSR value was 0.876133 (77.587572/88.556865), and the interval was 10 days. The difference of the UGSR was 0.019509 (0.876133–0.856624) between the two groups (the outpatient examination and preoperative positioning groups)
