Measurements of the Insula Volume Using MRI

Following the development of the neuroimaging sciences, the insula has been anatomically and functionally evaluated. With the new technology, important information about physiology and anatomy were obtained after CT, MR, and PET. Recent neuroimaging studies showed that volumetric changes of the insular cortex may be associated with many neuropsychiatric diseases. Most studies have shown that the volume of the insula in these psychiatric diseases was smaller than in healthy people. The main purpose of this book chapter is to provide some information about the volume of the insula and its clinical concepts.
