Foreword
Computed tomography has established itself as a novel diagnostic technique for car-
diovascular disease. The constant improvements in temporal and spatial resolution
of computed tomography systems permit increasingly stable imaging of the rapidly
moving heart, and as a result of these improvements the number of clinical indi-
cations for cardiac computed tomography is increasing. Indications have expanded
from prevention (where coronary calcium imaging is complemented by advanced
analysis of plaque morphology and composition) to modern interventional treatment
of cardiac disease; for example, detailed computed tomographic imaging is one of the
major contributors to the success of transcatheter aortic valve implantation (TAVI).
Based on the tremendous developments that we have witnessed in recent years, it
can be expected that computed tomography will continue to expand its role in the
work-up and management of cardiovascular disease, and everyone involved in the
diagnosis and treatment of heart disease should take advantage of these new imaging
capabilities.
Cardiac computed tomography requires specialist knowledge. Cardiologists need
to familiarize themselves with computed tomography technology, image interpreta-
tion tools, typical findings and artifacts, while radiologists need deeper insight in
cardiac anatomy, function, and pathophysiology than ever before. The second edition
of Cardiac CT Made Easy is therefore published just at the right time. Along with
the basic information everyone should know, and new and recent techniques, the
applications of cardiac computed tomography are thoroughly explained and put in
a clinical context. With a clear structure, well-written text, and a large number of
impressive illustrations, this book will be a very useful resource for all those new to
the field, and a trustworthy reference for those who have been involved for a while
but would like to update their knowledge or are looking for a resource to turn to for
very specific questions.
