sag·it·tal sec·tion

a cross section obtained by slicing, actually or through imaging techniques, the body or any part of the body, or any anatomic structure in the sagittal plane, that is, in a vertical plane parallel to the median plane. Inasmuch as actual sectioning in the sagittal plane results in right and left portions, an anatomic sagittal section may be a two-dimensional view of the cut surface on the medial aspect of either portion.

As a result, it was suggested that the 30-degree scanning angle in T2-weighted images might be optimum for showing the RCPmi because the length of the RCPmi was the longest in this oblique sagittal section. In this study, a reference value of imaging anatomical parameters of the RCPmi was set up on the basis of the scanning section of 30-degree angle: the length of the RCPmi was 21.2 [+ or -] 2.6 mm in male and 19.3 [+ or -] 2.4 mm in female, and the area of the RCPmi was (91.9 [+ or -] 27.2) mm2 in male and (73.3 [+ or -] 22.0) mm2 in female.
