A system and method for splicing medical image datasets are provided. The method for splicing medical image datasets comprises: segmenting first and second medical image datasets comprising an organ of interest and a nearby area to create a mask for points in the first and second medical image datasets, wherein the mask identifies points in the organ of interest and nearby area; and creating a spliced image of the first and second medical image datasets by using the points in the organ of interest and nearby area identified by the mask.
