Book excerpt: This new and improved 4th Edition of Don Ridgway?s unabashedly practical and famously unique how-to guide to vascular scanning will astound and delight both beginners and veterans who are cross-training in vascular ultrasound. Like previous editions, this one contains all of the features that have made this book so popular and useful.\\In this first all-color edition, the emphasis is on showing, not just telling: You will find dozens of new full-color technical and anatomic illustrations; 150+ duplex scans, color flow images, and Doppler waveforms; and scores of schematics, cross-sections, ultrasound images, and photographs?more than 700 illustrations in all. As praise for the previous editions suggests, you won?t find anything else like this guide for the relative novice: extremely reader-friendly, lavishly illustrated, and focused squarely on the real-world skill-building needs of both budding vascular sonographers and seasoned veterans.\\ As a welcome bonus, the 18-credit CME quiz at the end of the book can be combined with any of Davies? other 12-credit CME activities to help busy sonographers meet their ARDMS triennium requirements in two easy steps.
