Query: Good Book

I used this book to prepare for my CT registry. It was not the only book that I used but I felt that it was very helpful. I took, and passed, my registry in October 2006. This book contained a lot of questions that I actually had on my registry. Also this book has a lot of anatomy questions and there was a lot of anatomy on the registry. I highly recommend this book to anyone.
