Imaging modalities

Abstract

This chapter provides an overview of the different imaging modalities used for image-guided interventions, including x-ray computed tomography (CT) and fluoroscopy, nuclear medicine, magnetic resonance imaging (MRI), and ultrasound. The emphasis is on the distinguishing physical and engineering properties of each modality and how these characteristics translate into strengths and weaknesses for the end user. Because the imaging methods are very different, there is no single ideal modality for image-guided interventions; rather, they are largely complementary and can all provide valuable information about the patient. The chapter also covers current research topics in medical imaging relating to image-guided interventions and how these trends could potentially improve image-guided interventions in the future. © 2008 Springer US.
