Perfusion in medical science is the flow of blood or other fluid through or over tissue in an organ. Imaging is the viewing of such flow through a scanning machine, device or instrument.
A common example of perfusion is the myocardial nuclear perfusion test used to determine if there is insufficient blood in the heart and / or if there is a blockage in blood vessels. A small amount of thallium-201 or other radioactive substance (sometimes termed ‘contrast’) is injected into the veins of the patient, and images are then produced by a scanner, first at rest and later, after running on a treadmill.
The presence or absence of blockages in the form of fatty deposits (sometimes called ‘plaque’) on the walls of the blood vessels help determine if the patient has or does not have coronary artery disease, the leading cause of death in the United States today. The narrowing of the vessels reduces blood flow to the heart muscle. An insufficient blood supply to the heart is caused by the narrowing of the blood vessels.
This is often manifested in symptoms such as chest pain and shortness of breath, resulting from reduced oxygen that is carried through the blood.
The purpose of this book is to show and measure tissue perfusion in different organs, and to describe the various approaches to imaging that perfusion, states the editor Dr. Farhood Saremi.
The clinical applications of these techniques of perfusion and imaging are vast and quite broadly scattered in medical literature, the editor points out. This makes it quite difficult for radiologists and clinicians to understand the practical clinical implications of these diagnostic methods.
Eight-eight doctors of medicine and fields related to perfusion and imaging, from the United States and 13 other countries – Australia, Canada, Denmark, France, Germany, Greece, Italy, Japan, the Netherlands, Saudi Arabia, Spain, Switzerland, the United Kingdom – contributed material for this book, mainly writing its 35 chapters, which we present below to give you an overview of what you will (or will not) find in this volume:

Perhaps very few books are available in the market on the subject of perfusion imaging and this is one of those few. This work is an extensive one because it covers perfusion techniques and imaging of major parts of the human body. .
Among the major benefits of using this book are the following:
- Obtain optimal results from perfusion imaging of the brain, cardiac. Liver, kidney, prostate, and musculoskeletal system, as well as oncologic and pediatric applications
- Master all of today’s techniques and technologies, including new, faster CT scanners; MRI applications such as DSC< DCE, and ASL: contrast ultrasound, contrast echocardiography, and nuclear perfusion imaging; MDCT; close-reduction strategies; and other recent trends
- Build your interpretation skills with the aid of hundreds of high-resolution cross-sectional graphics demonstrating the imaging manifestations of various pathologies
