Anatomy and Normal Doppler Signatures of Abdominal Vessels
Doppler studies of the abdominal vessels demand an understanding of normal and abnormal blood flow patterns. The detection of changes in abdominal blood flow allows accurate diagnosis of arterial and venous abnormalities, including stenosis, occlusion, and thrombosis. As is mentioned in several chapters in this book, identification of changes
