An analysis of clinical outcomes using color Doppler ultrasound for thyroid disease

Abstract

Objective To increase the awareness of thyroid diseases through observing the relationship between ultrasound indications of thyroid and thyroid disease,and to enhance the understanding of thyroid disease through outpatient data.Methods Two hundred women aged 25 to 50 with thyroid imaging data were selected from the Department of Ultrasonography,the First Affiliated Hospital of Harbin Medical University.Seven indications including age,body weight,thyroid volume,the number of nodules,nodule size,nature of nodules and thyroid disease were recorded.Thyroid cases were divided into four groups based on their sonographic changes of color Doppler ultrasound:normal group (136 cases):sonographic changes of thyroid were approximately normal ; mild degree group (9 cases):consisting of patients with mild thyroid disease,diffused thyroid enlargement or combined cystic nodules; moderate degree group (38 cases):consisting of patients with moderate thyroid disease,hyperthyroidism or hypothyroidism; severe degree group (17 cases):consisting of patients with severe thyroid disease,thyroiditis and/or with hemorrhage and calcification.Data were analyzed using the method of clinical case observation and SPSS 16.0.Results We found that in mild degree group the discriminant coefficients of thyroid volume,the nature of thyroid nodules and nodule size were 0.085,0.169 and 0.695; but in sever degree group the corresponding values were 0.158,0.344 and 0.484,respectively,and the difference between the two groups was statistically significant (x2 =43.3,df =18,P ＜ 0.01).Conclusions The nature,size and area of thyroid nodules are closely related to the progression of thyroid disease.The color Doppler ultrasound data of outpatients as a part of hospital statistics have important theoretical and practical value.
