CT Teaching Manual: A Systematic Approach to CT Reading
This manual introduces you in an easily understandable way to the technology of, and the images produced by modern CT scanners.
You will begin by studying the atlas sections, learning step-by-step to interpret normal anatomic findings in the cross-sectional images. Even as a beginner you can systematically examine images of abnormalities and practice differential diagnoses.
The book explains how you can best prepare your patient for CT procedures and what your colleagues in the radiology unit need to know about your patient. If you are not versed in reading CT studies, the book will help you acquire the basics necessary for understanding your patient's images.
The book provides detailed information about contrast media, for example, when to use which medium to achieve optimal enhancement. Pharmacologic problems are dealt with, such as side effects or adverse reactions.
