A Review of Cardiac Radiology

Book Cover & Preview Text
1. The radiographic signs of
right heart failure consist of widening of the vascular pedicle with
enlargement of the superior vena cava and azygos vein, a posterior bulge of the
suprahepatic portion of the IVC on the lateral chest radiograph, thickening of the
chest wall, and CT evidence of passive congestion of the liver, enlargement of
the abdominal portion of the IVC and hepatic veins, and ascites.
2. Since widening of the
vascular pedicle can occur from chronic LV failure with plasma volume overload
from decreased renal perfusion without superimposed right heart failure, and
the other radiographic signs of right heart failure may either be absent
occasionally or require CT of the abdomen to identify, the clinical examination
is a better detector of right heart failure than the chest radiograph.

preload stress on the LV
a. Aortic valvular
regurgitation
1)
Cephalization
of pulmonary blood flow and other signs of PVH may be present.
2)
Left
ventricular enlargement (LVE) characteristic
3)
Left
atrial enlargement (LAE) may develop late from dilatation of mitral annulus.
4)
Enlarged
aorta, particularly the aortic arch (aortic knob) and descending aorta
b. Mitral valvular
regurgitation
1)
Cephalization
of pulmonary blood flow and other signs of PVH may be present.
2)
Usually
have both LAE and LVE, may also have enlarged left atrial appendage (LAA)

About the Book
A Review of Cardiac Radiology, by John H. Woodring, M.D.,
has been written as a guide to help diagnostic radiology residents prepare for
their written and oral board examinations in cardiac radiology. Both adult and
pediatric heart disease are covered in this text. A broad range of basic
material, including anatomy, physiology, embryology, histology, pathology,
cardiology, pediatrics, thoracic surgery, and cardiac radiology, is covered in
detail in order to provide the reader
with the fund of knowledge necessary to do well on the written board
examination. In addition, the book provides the reader with an organized
approach to interpreting chest radiographs of patients with cardiac disease
which is very useful in performing well on the oral board examination.
Appropriate differential diagnostic lists are provided for key patterns of
cardiac disease encountered on chest radiographs. The uses of CT and MR in the
evaluation of cardiac disease are discussed in detail as well. This book was specifically
written to encompass written board questions and oral board cases encountered
by diagnostic radiology residents over the last 25 years. This book could also
be of value to board certified radiologists who are preparing for recertifying
exams in cardiac radiology.
About the Author
John H. Woodring, M.D. has published over 100
scientific articles pertaining to cardiac and thoracic radiology. An expert
teacher, he has been recognized four times as the “Outstanding Teacher of the
Year” by his residents. He is a fellow of both the American College of Chest
Physicians and the American College of Radiology, and is a staff radiologist at
the Lexington Department of Veterans Affairs Medical Center and an Adjunct
Professor of Diagnostic Radiology at the University of Kentucky Medical Center
in Lexington, Kentucky. In this book, Dr. Woodring combines an approach to the
interpretation of chest radiographs useful on oral board exams in cardiac
radiology with basic material that is covered on the written board exams.
