抄録 :Purpose: Volume estimation of organs or fluid is one of the most important roles in autopsy. The aim of this study is to develop a volume estimation program for CT images of Digital Imaging and Communication in Medicine (DICOM) which runs on a personal computer, and to confirm the usefulness and accuracy of it. Materials and methods: We developed a program which extracted correct boundaries of the organs in spite of setting of rough region of interest (ROI). We retrospectively evaluated five postmortem CT (PMCT) examinations which were performed with a 64-row detector CT. Volume of five livers, five spleens, and 10 kidneys were evaluated by means of a general image processing program and our developed program. The averages of obtained volume and required time to set ROIs were analyzed with paired t-test.Results: There were no significant differences for the estimated volume of all organs between with the general image processing program and with our program. However, there were significant differences for the required time to set ROIs between with the two methods in all organs. The mean evaluation time was shortened by 52.0%, 67.2% and 74.0% in liver, spleen, and kidney, respectively. Conclusion: Our developed program provided correct volume value, and was able to reduce labor and time to set ROIs compared with using the general image processing program. Our program is useful to evaluate the volume on CT images of DICOM data especially in PMCT.
