摘　　要：目的评价SPECT计算甲状腺体积的准确性。方法1)采用SiemensE.cam型SPECT仪对13个甲状腺模型进行断层扫描,利用SPECT仪自带的体积计算软件计算甲状腺模型体积。2)甲状腺模型的实际体积等于其内充水的体积。3)将SPECT测定的结果与甲状腺模型实际体积进行统计分析。结果SPECT计算的甲状腺体积与实验模型实际体积无明显差异(t=0.273,p=0.79),两者有高度相关性(r=0.987,P<0.001)。结论SPECT能够准确计算甲状腺体积。Objective To assess the accuracy of thyroid volume （weight） by SPECT. Methods 1. 13 thyroid models were tomography by Siemens E.cam SPECT and their volumes were determined by using the volume-calculated soft of SPECT. 2. The actual volume of the models were equal to the volume of water in the models.3. The Volume （weight） of thyroid calculated by SPECT were compared with actual volume of thyroid models. Results The difference between actual and calculated volume of thyroid was not significant （p〉0.05）. The two results have a good correlation （r=0.987, p〈0.001）. Conelusions SPECT can calculate the： volume of thyroid accurately.
