摘　　要：应用B超和核素显像测量363例Graves甲亢患者甲状腺体积（重量），B超计算公式：每叶体积（ml）=π/6×长径（cm）×宽径（cm）×厚径（cm），按比重=1折算成重量（g）。核素显像计算公式：重量（g）=0．316×两叶平均高度（cm）×表面面积（cm2），结果表明两者的测值相关良好，r=0．93（P＜0．01），甲状腺重量在70．1～90．0g之间，两种方法测量结果无显著差异，可互相替代。但总体上核素显像平均测值大于B超平均测值．其主要影响因素是腺体厚度，核素显像法缺乏厚度，B超法较显像法更为准确。Thyroid volume was measured by ultrasonography in 363 patients with hyperthyroidism and compared with scintigraphy. The calculate formula used in ultrasonography is:V (ml) =π/6×height (cm) ×width (cm)×thickness (cm). Each 1 ml (volume) was assumed to equal lg (weight ). The formula for scintigraphy is weight (g) = 0. 316×mean height (cm) ×area(cm2). The correlation between two methods was significant, r= 0.93 (P＜0. 01 ). The results of two methods were not different when thyroid weights were 70. 1-90. 0g. The ultrasonography is more accurate than nuclear scintigraphy, because the later only provides two dimension data. It is concluded that thyrold volume mesurement by ultrasound is accurate, simple, and teproducible.
