[Frontal and sagittal sections in whole body x-ray computed tomography].

In sufficiently supple individuals, longitudinal sections are interesting in the case of extensive lesions because they provide a global view, whereas transverse axial sections give only a segmentary view of the pathological processus. They are of value in the study of lesions of the thorax, abdomen or pelvis. However, because of their anatomical and technical restrictions, they should be reserved for certain special cases.
