کتاب Clinical Emergency Medicine Casebook زبان اصلی

Emergency Medicine is not divided into specific areas of practice. Emergency room visitors come in all shapes and sizes, at any time of day or night, with a wide range of maladies. Emergency physicians need to become experts in diverse areas of medicine and to be able to make quick and informed decisions about patient care. A cornerstone of emergency medicine training is the constant drilling and re-drilling of simulated cases and clinical scenarios. This book offers a unique yet underutilized strategy for learning: a case-based approach from real patients and actual events. Each case provides the opportunity for learning essential clinical concepts. Focused exclusively on the needs of in-training emergency physicians and nurses, the book covers more than 100 common and unusual cases in emergency medicine. The procedures have been class-tested by the Stanford/Kaiser Emergency Medicine Residency Program.

کتاب Practical Nuclear Medicine زبان اصلی

Nuclear medicine plays a crucial role in patient care and this book is an essential guide for all practitioners to the many techniques that inform clinical management. The first part covers the scientific basis of nuclear medicine, the rest of the book deals with clinical applications. With a particular emphasis throughout on the practice of nuclear medicine, real-life practical problems encountered in nuclear medicine both in clinical practice and in the introduction of new techniques are addressed.

 

Following on the success of the previous edition, this book is also expanded by covering areas of development in nuclear medicine, such as PET, methods of tumor imaging and data processing. All illustrations for this new edition reflect current standards of image quality.

 

This practical approach results in a book which is invaluable to the radiologist, physician, physicist or technologist starting in nuclear medicine but also contains up-to-date advice for the most experienced practitioner.
