Measurement of the volume of the posterior cranial fossa using MRI

Abstract

Since the development of the neuroimaging sciences, the posterior cranial fossa (PCF) has been anatomically evaluated and measured volumetrically. Radiologically, the PCF volume is an important neuroimaging finding in Chiari malformation type I (CM I), but recent neuroimaging studies have revealed conflicting volumetric changes in the PCF in CM I patients. In this chapter, anatomical details of the PCF, different automated imaging techniques, and volumetric changes in the PCF will be reviewed. The main purpose is to gather information about automated imaging methods for the PCF and techniques for measuring brain substructures in patients with CM I and their clinical significance.
