Survival prediction of non-small cell lung cancer patients using radiomics analyses of cone-beam CT images.
BACKGROUND AND PURPOSE In this study we investigated the interchangeability of planning CT and cone-beam CT (CBCT) extracted radiomic features. Furthermore, a previously described CT based prognostic radiomic signature for non-small cell lung cancer (NSCLC) patients using CBCT based features was validated. MATERIAL AND METHODS One training dataset of 132 and two validation datasets of 62 and ...
متن کاملReproducibility with repeat CT in radiomics study for rectal cancer
PURPOSE To evaluate the reproducibility of radiomics features by repeating computed tomographic (CT) scans in rectal cancer. To choose stable radiomics features for rectal cancer. RESULTS Volume normalized features are much more reproducible than unnormalized features. The average value of all slices is the most reproducible feature type in rectal cancer. Different filters have little effect ...
متن کاملRadiomics in PET/CT: More Than Meets the Eye?
In the present issue of the J Nucl Med, Orlhac and colleagues present a study comparing visual assessment of uptake heterogeneity in positron emission tomography (PET) images by experts and a subset of radiomics metrics, namely textural features (TF). They exploited both clinical and simple simulated PET images, going further than previous studies carried out using clinical data only (4–6). Suc...

متن کاملDoes cone-beam CT alter treatment plans? Comparison of preoperative implant planning using panoramic versus cone-beam CT images
PURPOSE The present study was performed to compare the planning of implant placement based on panoramic radiography (PAN) and cone-beam computed tomography (CBCT) images, and to study the impact of the image dataset on the treatment planning. MATERIALS AND METHODS One hundred five partially edentulous patients (77 males, 28 females, mean age: 46 years, range: 26-67 years) seeking oral implant...
