The purpose of this book is to explain the current state of the art in
radiological examination, interpretation, and understanding of colonic
disease. The radiologic aspects of colon disease are combined here with
clinical information to serve both beginners and advanced students.
Major emphasis has been placed on technique for those radiologists,
residents, and technologists first undertaking modern gastrointestinal
radiographic techniques. The essentials of technique are stressed so
that the reader obtains a clear understanding of colon disease based on
sound practical information. We believe this book is a thorough and
practical text of particular interest to clinical radiologists and
gastroenterologists in their everyday practice, and also for teachers,
residents and medical students. Digital examination and sigmoidoscopy
are the first procedures in examination of the colon. Then, the
radiologic examination is the next most important procedure. Endoscopy
and biopsy play a compli- mentary role to the radiological examination.
The barium enema reveals quickly and early the overall status of the
colon and it can then guide endoscopy and biopsy together with
subsequent treatment. Surely, if the lesion is not detected our
clinical, radiologic, endoscopic, and therapeutic skills are of no use.
