Featuring over 900 state-of-the-art images, Radiology 101, Third Edition provides the basic groundwork necessary for interpreting images and understanding how current imaging modalities function. The first chapter explains the principles, capabilities, and limitations of each imaging modality. Subsequent chapters examine anatomic areas and organ systems, including a separate chapter on the pediatric chest and abdomen. Clearly labeled images show normal anatomy from various angles with various modalities and depict normal variants and common pathology. Each chapter includes suggested radiologic workups and key points summaries. This edition has extensive updates, especially on nuclear imaging (PET/CT), computed tomography (multi-slice), magnetic resonance (DWI, t-MRI, MRS), sonography (FAST), abdominal imaging (CT urography), mammography (digital mammograms), and the many indications for interventional radiology.
