The CNN-estimated dose level of CT images was highly correlated (r=0.998) with the actual CTDI. CT image noise level classification using CNN can be useful for the estimation of CT radiation dose. CT image noise level classification using CNN can be useful for the estimation of CT radiation dose. The purpose of this study was to propose a method for segmentation and volume measurement of graft liver and spleen of pediatric transplant recipients on digital imaging and communications in medicine (DICOM) -format images using U-Net and three-dimensional (3-D) workstations (3DWS) . For segmentation accuracy assessments, Dice coefficients were calculated for the graft liver and spleen. After verifying that the created DICOM-format images could be imported using the existing 3DWS, accuracy rates between the ground truth and segmentation images were calculated via mask processing. As per the verification results, Dice coefficients for the test data were as follows graft liver, 0.758 and spleen, 0.577. All created DICOM-format images were importable using the 3DWS, with accuracy rates of 87.10±4.70% and 80.27±11.29% for the graft liver and spleen, respectively. The U-Net could be used for graft liver and spleen segmentations, and volume measurement using 3DWS was simplified by this method. The U-Net could be used for graft liver and spleen segmentations, and volume measurement using 3DWS was simplified by this method. Automated analysis of skeletal muscle in whole-body computed tomography (CT) images uses bone information, but bone segmentation including the epiphysis is not achieved. The purpose of this research was the semantic segmentation of eight regions of upper and lower limb bones including the epiphysis in whole-body CT images. Our targets were left and right upper arms, forearms, thighs, and lower legs. We connected two 3D U-Nets in
