Abstract:
Objective To evaluate the diagnostic value of ultrasonography on thyroid microcarcinoma ,and to find out its sono-graphic characteristics .Methods Ultrasound performance of 206 thyroid microcarcinoma nodules in 150 patients confirmed by sur-gery and pathology were retrospectively analyzed ,nodules internal echo ,boundary ,the shape ,the blood flow and internal calcifica-tion and calcification size ,distribution and type were observed and compared with 82 benign nodules(diameter ≤1 cm) .Results In terms of solid low echo ,minicalcification ,aspect ratio≥1 ,rich blood flow and neck lymph node enlargement ,thyroid microcarcinoma were significantly higher than that of thyroid benign nodules (P<0 .05) .Ultrasonographic performance of thyroid microcarcinoma often presented as solid low echo ,irregular form ,aspect ratio ≥1 ,internal mostly small calcification ,edge blur and the surrounding small burrs .Color doppler blood flow showed that ,blood supply was rich in patients with strong nodules ,distribution was irregular , smaller nodules blood flow was not rich .Conclusion The two-dimensional and color doppler flow imaging(cdfi) might be has a im-portand value on thyroid microcarcinoma diagnosis .
