Limitations of angiography, the traditional invasive method for assessing vascular pathology, have led to an interest in alternative invasive techniques that visualize the arterial wall and allow characterization of plaque type. These alternative techniques, which include intravascular ultrasound, angioscopy, thermography, optical coherence tomography, near infrared spectroscopy, and intravascular magnetic resonance imaging are able to provide valuable information regarding plaque vulnerability, the composition of plaque, and luminal morphology.

Intravascular Imaging: Current Applications and Research Developments presents all available intravascular imaging techniques and analyzes their impact in clinical practice and research. This publication aims to inform medical specialists, biomedical engineers, bioinfomaticians, and researchers of current developments and future trends in intravascular imaging techniques, promoting continued evolution of this discipline.

Section three is devoted to thermography and is divided in two chapters. In the fist we analyze the basic principles of thermography, discuss its limitations, and present the available devices used to measure in vivo the temperature of the coronary atherosclerotic plaques. This chapter is completed with the description of microwave radiometry, an alternative technique that provides non-invasive measurements of the heating of the plaque, and is currently under clinical evaluation. In the second chapter we review the literature and present data from in vitro and in vivo studies that implemented thermography to measure the coronary wall temperature. These studies have improved our knowledge about the association between arterial wall inflammation and plaque vulnerability helped us to identify morphological characteristics associated with high risk plaques, and allowed us to assess their prevalence in different populations and the anti-inflammatory efficacy of various pharmacological treatments.

Section four deals with OCT and is divided in four chapters. The first chapter describes the engineering behind OCT image acquisition, while the second chapter focuses on the interpretation of OCT images and presents the available techniques developed for automated OCT processing. The third and the fourth chapter discuss the utility of this imaging technique in the current clinical practice and research arena.

NIRS is described in section five. Initially, we present the physical principles of NIRS and highlight its advantages in analyzing coronary wall tissue. In the main focus of the chapter we describe the NIRS system and present the results of the most important in vitro and in vivo validation studies. Finally, we discuss the clinical value of NIRS in assessing outcome after pharmaceutical or percutaneous coronary interventions and in detecting high risk patients who would be benefit by aggressive medical treatment.

Section six focuses on ICE. It describes the available devices and presents an overview of the typical images obtained during ICE examination. In addition, it discusses the current clinical applications of ICE in electrophysiology and structural interventional cardiology, and concludes with its limitations.

Section seven summarizes the current status of cardiovascular imaging. The first chapter of this section is devoted to the intravascular imaging techniques and particularly, IVUS and OCT, which are mainly used in clinical settings. The book focuses on their value in the assessment of the extent and the severity of coronary atherosclerosis and their utility in treatment planning during complex percutaneous coronary interventions. The second chapter deals with the non invasive imaging. It presents the current applications of non invasive imaging in portraying and assessing coronary atherosclerosis discusses its potentialities in the detection of vulnerable plaques and concludes with its current limitations.

Hybrid imaging is based on the integration of data provided by different imaging techniques and provides models which allow a more comprehensive and complete representation of coronary artery morphology. Today there are numerous data fusion methodologies with an evidenced based role in the diagnosis of coronary artery disease and have enriched our understanding about the atherosclerotic evolution. In section eight the available data fusion techniques are reviewed, and their clinical and research potentialities are discussed.

Blood flow haemodynamics appear to play a significant role in plaque development and destabilization. The current developments in intravascular imaging have allowed reliable representation of vessel’s morphology and geometry and permitted in vivo study of the role of local haemodynamics in the atherosclerotic evolution. Section nine provides the definition regarding the haemodynamic forces and flow patterns, reviews the literature, and cites the evidence concerning the effect of blood flow on atherosclerotic process.

Finally, the last section is devoted to the future trends in cardiovascular imaging. In the first chapter we analyze the necessity in developing new invasive imaging techniques, which will allow more accurate assessment of the anatomical and histopathological characteristics associated with increased plaque vulnerability. The second chapter discusses the potentialities of non invasive imaging modalities, and particularly, of multi slice computed tomography. It summarizes the current clinical utility of this promising imaging technique and attempts to foresee its future clinical and research applications. The last chapter is devoted to imaging techniques applied not to assess coronary morphology and anatomy but mainly to detect other features associated with increased vulnerability, such as the biomechanical profile of the plaque, or the presence of inflammation and increased neo-vascularization, and aims to highlight the variety of the imaging options and the need to invest in the early detection of vulnerable plaques.

We would like to thank all authors for their valuable contributions, the reviewers for the careful review, as well as the advisory editorial board for its valuable comments and suggestions.
