✦ Synopsis

Measurement employing the concept of the centroid is the most accurate way to study the radiographic anatomy of the posterior fossa. The normal measurements in Japanese subjects and as reported by Ross and du Boulay correlated well. We have developed a new radiographic centroid based on the morbid anatomy of the posterior fossa. The normal measurement in the Japanese by this method is also presented.

The centroid of the mid-sagittal plane of the posterior fossa seems to be the most accurate reference point for the angiographic measurements in relation to the choroid plexus of the fourth ventricle. We studied the normal vertebral arteriograms in the Japanese by the method of Ross and du Boulay [6]. Thereafter, we devised modified boundaries of the radiographic posterior fossa, with the correlative study in the postmortem angiograms. Normal measurements of the radiographic posterior fossa in the Japanese by our method are presented.
