Abstract:
Objective To explore the diagnostic value of CT in thyroid carcinoma , thyroid adenoma and nodular goiter .Methods CT manifestations of 55 cases with thyroid disease were retrospectively analyzed ,among them 6 cases had 2 kinds of lesions , 20 cases had thyroid carcinoma , 22 cases had thyroid adenoma and 15 cases had nodular goiter .The lesions'location, number, density, margin, enhancement type , neighbor structures chan-ges and cervical lymph nodes were evaluated .Results Thyroid carcinoma , thyroid adenoma and nodular goiter were mainly located in single lobe and solitary , and there were no significant differences among the 3 types(P>0.05).All thyroid carcinoma lesions were with slightly low density (100%, 20/20)with calcification 75%(15/20), which were significantly higher than those of thyroid adenoma 64%(14/22),23%(5/22)and nodular goiter 47%(7/15),40%(6/15)respectively.The differences had statistical significance (P<0.05).Most thyroid ade-noma had clear margin 91%(20/22),which had significant differences with thyroid carcinoma 35%(7/20) and nodular goiter 60%(9/15)(P<0.05).80%(16/20)of the thyroid carcinoma had inhomogeneous enhancement and 64%(14/22)of the thyroid adenoma had markedly inhomogeneous enhancement .The difference had statisti-cal significance(P<0.05).Neighbor structures were compressed and displaced .7 cases(35%,7/20)of thyroid carcinomas invaded neighbor structures and 14 cases ( 70%,14/20 ) had cervical lymph nodes metastasis .Con-clusion CT manifestations of thyroid carcinoma , thyroid adenoma and nodular goiter were different , thus CT has great value in the diagnosis .
