Abstract:
Objective To quantitatively observe the value of relationship between nodule and corresponding capsular with ultrasonography in assessment of malignant and benign thyroid nodules.Methods A total of 79 cases with subcapsular tumors of thyroid gland confirmed pathologically were analyzed retrospectively,and the relationship between tumors and capsule was analyzed.Longitudinal diameter of nodules (from the junction of nodule and capsule to the deepest of nodule,V) and distance from nodule protruding thyroid capsule to the highest point of nodule (L) were measured,and L/V was evaluated.Diagnostic efficiency of L/V in diagnosis of malignant thyroid nodule was evaluated.Results The average L/V of benign and malignant nodules was 0.241± 0.041 and 0.162± 0.054,respectively (t=-7.367,P<0.01).The area under ROC curve of L/V in diagnosis of benign and malignant thyroid nodules was 0.87 (P<0.01).When L/V=0.225,the sensitivity was 82.17%,and the specificity was 87.53%;when L/V=0.245,the sensitivity was 67.10 %,and the specificity was 95.12%.Conclusion Ultrasonography can clearly show the relationship between thyroid nodules and capsule,and L/V can be used for differential diagnosis of benign and malignant thyroid nodules.
