Abstract：Objective To explore a simple and accurate method for determining the compression ratio of lung in pneumothorax and liquid pneumothorax with MDCT Tissue Segmentation technology.Methods MDCT Tissue Segmentation technique was ap-plied to measure the volume of the compressed lung, the gas, and liquid in anocelia, then, the results were compared with those in pneumothorax by X-ray measurement and grade method and, meanwhile, the specific and accuracy method in the measurement of the volume of gas and liquid in anocelia was determined.Results The measurement of the ratio of gas or/and liquid volume in anocelia and the sum of the volume and the volume of compressed lung ( anocelia volume) was presented as G/G+L or G+E/G+E+L.The the ratio of compressed lung was calculated.The pneumothorax grade was determined as follows:less than or equal to 25%was grade I, more than 25%or less than 50%was grade II, more than or equal to 50% was grade III.Conclusion MDCT Tissue Segmentation technique is a simple and accurate way for measuring the volume of gas or/and liquid volume in anoce-lia and lung, and more accurate for grading the pneumothorax.
