Abstract

The sensitivity and specificity of 2-D and 3-D echocardiographic images for the detection of selected morphological abnormalities were compared using receiver operating characteristic (ROC) analysis. Five experienced clinical echocardiographers blinded to the patients' diagnosesevaluated the 20 original static 2-D image sets and 20 corresponding 3-D reconstructions using a five point categorical scale that ranged from definitely abnormal to definitely normal. The ROC curve for the 3-D images was significantly (P < 0.05) closer to the ideal discrimination function than was the ROC curve for the 2-D transesophageal images (i.e., the sensitivity of the 3-D images was higher than that of the 2-D sequential images at the same specificity). In conclusion: 3-D transesophageal images provided better visual clues for the identificationof morphological abnormalities than did serial 2-D echocardiographic images despite the same input information in both image formats. The use of ROC analysis assisted in the comparison of these two imaging techniques.
