ABSTRACT
Objective To investigate the accuracy and missed diagnosis rate of preoperative ultrasound in the diagnosis of thyroid carcinoma . Methods With the method of natural language recognition ,816 solitary thyroid nodules which received thyroidectomy were enrolled for the analysis of preoperative ultrasound examination and post-operative pathology results . The accuracy and the rate of missed diagnosis of ultrasonography for the diagnosis of thyroid carcinoma and lymph node metastasis were evaluated with the pathological results as the gold standard . Results There were 783 ( 96 .0% ) malignant thyroid tumors ,6 ( 0 .7% ) follicular tumor with uncertain malignant potential ,and 27 ( 3 .3% ) benign thyroid tumors . Ultrasonography yielded an accuracy of 96 .1% in the differential diagnosis between benign and malignant thyroid nodules and an accuracy of 94 .5% in the quantification of nodule numbers . 5 .5% of solitary nodules reported by ultrasound were proved to be 2 or more malignant nodules after the surgery . Regarding the diagnosis of central lymph node ,the preoperative ultrasound yielded an accuracy of 73 .0%and a misdiagnosis rate of 38 .7% . For the lateral neck lymph node ,the accuracy was 88 .3% ,and the misdiagnosis rate was 3 .4% . Conclusions Natural language recognition method can assist clinical research . Ultrasonography is valuable in the diagnosis of thyroid carcinomas and neck lymph nodes . However , ultrasonography has a certain rate of misdiagnosis for the quantification of nodule numbers ,and for the diagnosis of lymph nodes in central and lateral necks .
