Investigation of anorectal disorders has become a very
wide field reaching from case history and simple plain
radiography to advanced techniques such as defecography,
nuclear medicine, endosonography, computed tomography, and
magnetic resonance imaging. The place and value of
defecography, thedynamic demonstration of bowel evacuation,
have not previously been clearly defined. In this highly
illustrated volume, radiologists experienced in thisfield
describe techniques, radiation risks, and the interpretation
of normal and abnormal findings using the aforementioned
techniques of investigation. Anorectal surgeons and gastro-
enterologists also participatein the discussion of
indications and the influence of abnormal findings on
patient management. This book will be helpful as a practical
guide tothe choice, performance, and interpretation of the
appropriate investigationfor a patient with functional
anorectal disorders. As such it represents an excellent
addition to the library of every physician and specialist
withan interest in anorectal disease.
