Query: several typos and incorrect answers

I used this book as I was studying for my nuclear radiology CAQ. Some of the PET questions are outdated, and I found a few typos and wrong answers to be pretty distracting. It gives a good superficial review of various topics and gave me a good reason to review the topics in a text book, but I wouldn't recommend it for those who are not already pretty familiar with nuclear radiology.
