Abstract
Objective:To explore the diagnostic value of CT features on thyroid nodule.Methods:The plain and three-phase enhanced CT scan images of 30 cases with thyroid nodules (38 nodules) proved with pathology were analyzed retrospectively,and two experienced senior doctors were responsible to evaluate each CT feature and analyzed the value of them in qualitative diagnosis.Results:The boundaries of 33 benign nodules were clear with complete or incomplete strengthened envelope.The nodular solid part was significantly enhanced with non-enhanced cystic necrotic area.There was outflow type of 27 cases in the strengthened timedensity curve,6 benign nodules could not be classified due to that the cystic portion is more and the solid part is less and the CT value can't be measured accurately,4 nodules occurred with porphyritic,nodular and cyclic coarse calcifications.The cervical Ⅵ region of one case with multiple thyroid nodules had the same form.5 malignant nodules showed blurred edges,no envelope,and ramp platform type time-density curve,3 cases had regional lymph node metastasis and 2 nodules had punctate cluster distributed calcifications.Conclusion:Lymph node metastasis is the leading indicator that distinguishes benign thyroid nodules from the malignant ones.Nodule border,the presence of capsule,calcification shape,time-density curve,and other CT signs are effective methods to identify the benign and malignant thyroid nodules.关键词
