At the end of each chapter, the authors present the imaging approaches. understanding, and (3) the medical -imaging researcher requiring a comprehensive resource. Key points and summarized answers to the important clinical issues are at the beginning of the chapters, so the. review in the form of summary tables and flow charts. The imaging case series highlights the strengths and limitations of the different imaging studies with vivid examples. Toward the end of the
