This book is an attempt to bridge the interface between referring clinicians and radiologists
when faced with a patient suspected of having a complex or unusual abdominal
condition. The emphasis is on the choice of imaging procedures, expected diagnostic
yield, a discussion of pertinent imaging findings, and the possible differential diagnosis.
The rapid proliferation of imaging techniques provides a bewildering array of
choices to the referring physician.Thus when faced with a suspected biliary abnormality,
should one suggest traditional endoscopic retrograde cholangiography, or is noninvasive
and noncontrast magnetic resonance (MR) cholangiography or even contrast-aided
computed tomography (CT) cholangiography more appropriate? What is the role of CT
virtual colonoscopy? Is it limited to colon cancer screening or does it have a role in cancer
staging?
This book discusses imaging topics of those structures that fall in the purview of the
gastroenterologist, urologist, general surgeon, and related specialist. The anatomic limits
of the abdomen are somewhat stretched to include the esophagus superiorly, and the
aorta, inferior vena cava, and adjacent structures posteriorly. The emphasis is on new
imaging findings and innovations. This book also discusses the clinical aspects of a
disease needed to formulate a rational diagnostic approach, but basic research, results
of animal studies, and imaging research are not discussed as they are not pertinent to
clinical medicine. Because of space limitations, fetal imaging and choosing a contrast
agent are not discussed. Also, laboratory findings and therapeutic options are not discussed,
except for those having a bearing on subsequent diagnostic studies.
This book is intended to be used as a reference for the atypical and unique presentation
and newer diagnostic imaging modalities. Publications of unusual clinical and
imaging finding are accentuated, and common imaging studies of common disorders are
only mentioned in passing, if they are applicable. |
