Physiological Interactions

  • Chapter
Integrated Cardiothoracic Imaging with MDCT

Part of the book series: Medical Radiology ((Med Radiol Diagn Imaging))

Abstract

Improvement in both temporal and spatial resolution of MDCT has brought the ability to explore both the heart and lung within a single examination and opened the field of functional evaluation. However, interactions between heart and lung have long been identified as important physiological phenomena in pathology (Pinsky 2005). For the radiologist, they are involved in difficulties of interpretation in a MDCT thorax examination and in the understanding of observations in physiological normal or near-normal clinical situations. In this chapter, after a brief overview of physiological heart-lung interactions, we will overview the consequences in imaging the heart and lung with the effects of the beating heart on thoracic organs, those of respiratory maneuvers, and of cardiac functional parameters on vascular enhancement. Then, interactions among the pulmonary, systemic circulation, and lymphatic circulations in normal subjects will be considered.
