Sommario/riassunto |
|
"Doppler Echocardiography for the Small Animal Practitioner provides a clinically oriented quick reference to using color flow and spectral Doppler to interpret echocardiographic findings, enabling readers to learn and apply these techniques and acquire background knowledge of technical factors affecting diagnostic color and spectral Doppler. Practically, the text also serves as a quick checklist for the Doppler features of commonly acquired cardiac diseases in the dog and cat. To aid in reader comprehension, the text contains color images and video clips to support the descriptions. This handbook is not intended as a comprehensive explanation of the echocardiographic features associated with heart disease in animals. Rather, it is intended as the next step for the general practitioner and the non-cardiac specialist that have learned to acquire diagnostic 2D and M-Mode echocardiographic studies"-- |
