How to use: This book is a valuable tool for learning about gastrointestinal radiology. You can read it cover - to - cover to gain a comprehensive understanding or refer to specific x - ray images when needed. It's suitable for students, researchers, and medical professionals. Note: Be careful when handling the book because some x - ray images are already missing. Avoid excessive bending to prevent further damage to the creased pages. Maintenance: Keep the book in a dry and clean place. If there is dust on the covers, you can gently wipe it off with a soft cloth. When not in use, store it on a flat surface to maintain the integrity of the spiral binding.
