CT Scanning

Since its introduction in 1972, X-ray computed tomography (CT) has evolved into an essential diagnostic imaging tool for a continually increasing variety of clinical applications. The goal of this book was not simply to summarize currently available CT imaging techniques but also to provide clinical perspectives, advances in hybrid technologies, new applications other than medicine and an outlook on future developments. Major experts in this growing field contributed to this book, which is geared to radiologists, orthopedic surgeons, engineers, and clinical and basic researchers. We believe that CT scanning is an effective and essential tools in treatment planning, basic understanding of physiology, and and tackling the ever-increasing challenge of diagnosis in our society

A Posteriori Validation of Pre-Operative Planning in Functional Neurosurgery By Quantification of Brain Pneumocephalus

Functional neurosurgery for Parkinson's disease is based on the stereotactic introduction of electrodes in a small, deeply located, nucleus of the brain. This nucleus is targeted on pre-operative stereotactic MR acquisitions. The procedure is time-consuming and can lead to the development of a pneumocephalus (presence of air in the intracanial cavity) because of CSF leak. This pneumocephalus leads to a brain shift which can yield a significative deformation of the entire brain and thus cause potential errors in the pre-operatively determined position of the stereotactic targets. In this paper, we conduct an a posteriori validation of the pre-operative planning, by quantifying brain pneumocephalus from the registration of pre and immediate post-operative MR acquisitions
