目得：建立一种实用的方法估计胸腔积液的体积与sonography.Materials和方法：51例患者进行了超声检查的胸膜腔，而仰卧位。将超声检查结果和侧卧位X线检查结果与实际积液量进行比较。最大厚度的胸腔积液层的测量与两种方式，而实际积液量是通过完全drainage.Results：超声测量相关的统计学显着更好的实际积液量（r = 0.80）比放射学测量（r = 0.58）（P小于或等于0.05）。通过超声测量，20 mm积液宽度的平均体积为380 mL +/- 130（标准差），而40 mm积液宽度的平均体积为1，000 mL +/- 330。超声测量的预测误差（平均224 mL）显著小于X线片测量（平均465 mL）（P <0.002）。结论：在胸腔积液定量方面，超声测量方法优于X线片测量。
PURPOSE: To develop a practical method of estimating the volume of pleural effusions with sonography.MATERIALS AND METHODS: Fifty-one patients underwent sonography of the pleural space while supine. Sonographic results and results of lateral decubitus radiography were compared with actual effusion volumes. The maximum thickness of the pleural fluid layer was measured with both modalities, while actual effusion volume was determined by means of complete drainage.RESULTS: Sonographic measurements correlated statistically significantly better with actual effusion volume (r = .80) than did radiographic measurements (r = .58) (P less than or equal to .05). With sonographic measurement, an effusion width of 20 mm had a mean volume of 380 mL +/- 130 (standard deviation), while one of 40 mm had a mean volume of 1,000 mL +/- 330. Prediction error with sonographic measurement (mean, 224 mL) was statistically significantly less (P less than or equal to .002) than that with radiographic measurement (mean, 465 mL).CONCLUSION: In quantification of pleural effusions, the sonographic measurement method presented is preferable to radiographic measurement.
