Abstract：Objective To explore characteristics of color doppler ultrasound in thyroid carcinoma. Methods The study included 137 patients with 146 malignant nodules which were confirmed by pathological diagnosis. The blood flow char-acteristics of color doppler ultrasound were retrospectively analyzed. Results Among the 146 nodules, 91. 10% showed blood flow signals, including peripheral type (26. 03%), internal type (42. 47%) and penetration type (22. 60%). Blood flow classifications showed that 8. 90% of the lesions were grade 0, 34. 93% were grade I, 37. 67% were gradeⅡ, and 18. 94%were grade Ⅲ. The blood flow patterns and grades were relative to the sizes of the nodule. As the sizes increased, the blood flow tended to be penetration type, and blood grade increased (r=0. 867, P<0. 05;r=0. 776, P<0. 05). As the lesion si-zes increased, the Vmax and RI increased, and the differences of Vmax and RI were significant among various sizes of lesions (P<0. 05). Conclusion For those lesions with diameter bigger than 10 mm, blood flow is more abundant along with its size, and blood flow pattern may tend to be clutter, and Vmax and RI increase gradually. While lesions with diameter less than or equal to 10 mm may have low blood flow.
