Abstract: Objective To evaluate the diagnostic value of Doppler sonography in occult carcinoma of the thyroid(OCT) and its ultrasound features.Methods Uhrasonography and clinical data of 80 cases with OCT confinned by operative pathology were analyzed retrospectively.Results In 80 cases with OCT,a single cancer nodules in 45 cases(56.3%),more than 35 cases of cancer nodules(43.8%);In 135 focus imaging,among border not clear 64 focus(47.7%),the border clear no envelope of 66 focus (48.9%),the border clearance of a halo 5 focus (3.7%);The nodules were slightly lower echo of 100 focus(74.1%),mixed 28 focus(20.7%),slightly stronger echo of 7 focus(5.2%);35 cases of a cancer;the 50 focus showed nodules with blood flow,in which rich 35 focus (70.0%),strip-signal blood flow 14 focus(30.0%);In 35 cases with OCT,among nodular micro-calcification appeared in the 31 cases(88.6%),coarse calcification in 3 cases(9.7%),1 case of arc-shaped calcification(2.9%).Conclusion The diagnosis value of high-frequency sonography was significance in patients with OCT.
