［Abstract］ Objective To study radiological_anatomy of greater omentum and to address the related clinical implications, and to provide anatomic data for the radiological diagnosis and surgical application of greater omentum. Methods The anatomic distribution and morphology of the greater omentum as well as the anatomic relationship of the organs in the vicinity were analyzed by using axial, coronal, sagittal and 3D images from 16-detector row spiral CT scans of 60 individuals. We assessed the advantages of these images as well as the clinical significance. The data were recorded and analyzed by using SPSS115 software. Results 1. Advantages of three sections: axial section, the display of the fatty tissue and the anatomic distribution; coronal section, the vasculature; sagittal section, the anatomic relationship of neighbour organs. 2. Three-dimensional reformatted images showed the return of the gastroepiploic vein. 3. Gastrocolic trunk was revealed in 67.2% of cases. The free_hanging portion seemed to have the capability of ‘migration’: it located in the subphrenic spaces in 207% of cases and distributed in the right lower quadrant predominantly in 17.2% of cases. The CT value of fatty density within greater omentum was (-104.97±10.78)Hu and no statistical significance was found in the difference between greater omentum and the subcutaneous tissue. Conclusion Gastroepiploic vessel is the landmark for the location of greater omentum. Axial, coronal and sagittal sections together with 3D reconstruction images could produce a full display of greater omentum and provide valuable data for the radiologic
