An automated, computer-aided diagnosis CAD algorithm for the quantification of pneumothoraces from Multidetector Computed Tomography MDCT images has been developed. Algorithm performance was evaluated through comparison to manual segmentation by expert radiologists. A combination of two-dimensional and three-dimensional processing techniques was incorporated to reduce required processing time by two-thirds as compared to similar techniques. Volumetric measurements on relative pneumothorax size were obtained and the overall performance of the automated method shows an average error of just below 1%.
