Simulated 3-dimensional (3-D) representation of computerized data is a valuable diagnostic tool in evaluation of tumors of the central nervous system. Several reports exist regarding the clinical value of 3-D imaging, but there is little objective evidence to quantify improved performance from the images. The purpose of this study was to quantify the efficacy of simulated 3-D versus 2-D image interpretation in a nonclinical model. A 3- tiered, 3-D model was constructed, and objects were placed in varied positions. CT was then performed on each of the models. Fifty-three subjects were shown the CT images and asked to reconstruct the model as depicted by either 2-D or simulated 3-D images. Performance between subject groups was different depending on clinical experience. In addition, it was found that the 3-D representation of data allowed for a significantly faster performance of the task of image interpretation and reconstruction of the model.
