I am again grateful to the many thousands of you whom I have never met but who found a website called Learning Radiology helpful, making it so popular that it played a role launching the first edition of this book, which itself was so popular that it led to this third edition.

For their help and suggestions, I thank David Saul, MD, one of our radiology residents, who made invaluable suggestions about how this edition could be changed. Daniel Kowal, MD, a radiologist who graduated from our program, did an absolutely wonderful job in simplifying the complexities of MRI again in the chapter he wrote. Jeffrey Cruz, MD, one of our residents, helped out with the online Radiation Safety and Dose module, and Sherif Saad, MD, contributed an illustration.

I thank Chris Kim, MD; Susan Summerton, MD; Mindy Horrow, MD; Peter Wang, MD; and Huyen Tran, MD, for supplying additional images for this edition. And thanks to Mindy Horrow, MD; Eric Faerber, MD; and Brooke Devenney-Cakir, MD, for reviewing chapters from this text.

I certainly want to recognize and again thank Jim Merritt and Katy Meert from Elsevier for their support and assistance.

I also acknowledge the hundreds of radiology residents and medical students who, over the years, have provided me with an audience of motivated learners, without whom a teacher would have no one to teach.

Finally, I want to thank my wonderful wife, Pat, who has encouraged me throughout the project, and my family.

William Herring MD, FACR

The links to the American College of Radiology's Appropriateness Criteria provided below explain which imaging study to order under certain clinical circumstances. These guidelines were developed by a series of expert panels consisting of diagnostic radiologists, interventional radiologists, and radiation oncologists, as well as leaders in other specialties. These are evidence-based guidelines designed to assist health-care providers in making the most appropriate imaging or treatment decision for a patient with a specific clinical condition.

Here you are at the end of the book. Finished the text already? That was speedy reading on your part. Here are the answers to the quiz that appears in .

FIGURE 1-1 Small-bowel obstruction. There are multiple air-filled and dilated loops of small bowel (white arrows) with virtually no gas in the large bowel. The stomach (S) is also dilated. The disproportionate dilatation of small bowel is indicative of a mechanical small bowel obstruction caused, in this case, by adhesions from previous surgery.

FIGURE 1-2 Subdural hematoma. A curvilinear band of increased attenuation in the right parietal region (black arrows) is causing a subfalcine shift of the midline structures to the left (white arrow). The crescentric increased density, paralleling the inner table, is classic for a subdural collection. The patient fell from a height and struck his head.
