Is there a reliable correlation between computer-aided diagnosis (CAD) results from CT images and information from PET images in longitudinal studies: an example study in interstitial lung disease

Summary

The study examined whether changes in computed tomography (CT) computer-aided diagnosis (CAD) results corresponded with texture-based measures from positron emission tomography (PET) in longitudinal imaging of interstitial lung disease. The reported approach used gray-level co-occurrence matrix texture features from CT regions of interest and kurtosis, skewness, and histogram features from PET images. The abstract reports a correlation between CT and PET changes related to diffuse lung parenchymal disease. These findings are from a meeting abstract; the available record does not provide enough information to assess the study’s design limitations or establish prospective clinical validation.
