Retrospective Analysis Of 80 Cases Of Thyroid Adenoma And Nodular Goiter Ultrasound Diagnosis

Objective:To study two-dimensional,color Doppler ultrasound and contrast-enhanced ultrasonography(CEUS) of thyroid adenoma and nodular goiter the diagnosis and differential diagnosis.Methods:Retrospective analysis confirmed by surgery and pathology of 26 cases of thyroid adenoma and 54 cases of patients with nodular goiter patients with imaging data, and same as to observe the dynamic enhancement pattern of each nodule,these two sets of two-dimensional sound and color Doppler flow imaging (CDFI ) a comparative analysis of image characteristics, and diagnostic imaging results and pathological contrast.Results:1.54 cases of nodular goiter two-dimensional ultrasonography and 26 cases of thyroid adenoma compare the size, internal echo nodules, nodules around the capsule, there was no significant difference (P> 0.05), in the number of nodules, colon section size of edge halo nodules there was a significant difference (P <0.05). Glands with nodular goiter can be seen an increase in blood flow signal of the point, but the internal and peripheral nodules less blood flow signals, and even no-flow signal. Thyroid adenoma and the surrounding blood flow signals within the more abundant, was part of the distribution ring. Thyroid adenoma and nodular goiter in the nodules and the surrounding blood flow signals within the difference was significant (P <0.05). Thyroid adenoma and nodular goiter in the parameters of peripheral blood flow (Vmax) (11.0±0.10cm/svs6.3±4.1cm / s) and RI (0.47±0.08vs0.13±0.14) there was a significant difference sex (P <0.05), the former than the latter, and nodular goiter and thyroid adenoma blood parameters (Vmin) There was no significant difference (P> 0.05). Correct diagnosis of nodular goiter accounted for 94% (51/54), misdiagnosed as adenoma accounted for 5.6% (3 / 54), accounting for, the correct diagnosis of thyroid adenoma accounted for 84.7% (22/26), misdiagnosed as nodular goiter accounted for 15.3% (4 / 26).2. In the 9 follicular adenoma cases. 7 cases showed lately wash in,with a homogeneous Peripheral pattem enhancement, lately Wash out in comparison with the adjacnt thyroid parenchyma. The Enhancement intensities were lower than those in adjacent thyroid parenchyma.In the 16 nodular goiter cases,all cases showed early or lately wash in,with a Peripheral pattern enhancement and centripetal progression,early or lately wash out in comparison with the adjacent thyroid parenchyma.,16 Cases showed that the enhanced intensities were higher than or approximate to those of adjacent thyroid parenchyma.【Conclusion】based on two-dimensional sonographic features of thyroid nodule size, number, shape, location, and cystic change and the internal echo with the surrounding tissue and so on, combined with color Doppler and pulsed Doppler flow parameters of nodular goiter and thyroid adenoma to make more accurate diagnosis and differential diagnosis.
