Determining the Laterality of the Fetal Body and Image Orientation

Abstract

In the normal human, the midline sagittal plane divides the body into two sides that are mirror images of each other in term of their skeletal and muscular structure. However, many organs within the body, even those that are paired (such as lungs, bronchi, kidneys), show a distinctly lateralized arrangement. This lateralization is most striking in unpaired organs. In the large majority of normal subjects, the liver is predominantly to the right of the midline, whereas the stomach and spleen are located to the left. The heart sits in the mediastinum, with two thirds in the left side of the chest and its long axis also pointing left. This pattern of lateralization is called situs solitus, which means usual arrangement.
