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' diagnoses evaluated 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 lt; 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 identification of 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.
