Stereotactic Dissection of an Injected Brain-Skull Preparation: Cortical Branches of the Middle Cerebral Artery in Specimen I-L
The previous chapter has shown the general arrangement of the superficial sulcal pattern on the undissected curved hemispheric surfaces. Juxtaposition of the six different orthogonal views allows the localization of the sulcal openings in radiographic projections. It is perhaps useful to stress the importance of foreshortening effects, which must be taken into account in the interpretation of the cortical angiogram. The superior and inferior views of the hemispheres illustrate particularly well the extent of the surfaces foreshortened in both of the usual angiographic projections, the profile and frontal views. This might well be one of the reasons why these regions are not covered by the usual templates and localization diagrams published in the literature.
