Bone age assessment, a crucial part of the diagnosis and management of pediatric growth disorders as well as the timing of certain pediatric orthopedic procedures, has for decades depended on the meticulous examination of plain radiographs. Examining the subtle changes present within the maturing human hand often proves to be challenging and time-consuming.Building on the popular Greulich and Pyle atlas, this book modernizes the method for pediatric skeletal maturity determination. It offers a wealth of images, carefully mined from thousands of digital radiographs from University of Virginia's Picture Archiving and Communication System (PACS), edited to best demonstrate important developmental bone features, and organized by age and sex for rapid reference. To expedite learning and clinical image analysis, images come in pairs: annotated and unannotated, for easy comparison. Succinct annotations on the images replace lengthy text to provide a quicker and clearer understanding of the skeletal age. These annotations highlight important and subtle features to help distinguish images that otherwise look superficially alike. The result is an atlas of exceptionally high quality skeletal radiographic standards that capture both the major and finer details of the accepted standards of Greulich and Pyle. The user-friendly format of this book enables a faster, more accurate, and more educational approach to determining skeletal maturity. The Digital Bone Age Companion packaged with the book is a computer program that facilitates viewing of the atlas images in digital format. Users can easily zoom in on radiographic features, set image level and width to their preference, and compare two or three reference standards side-by-side for difficult cases. Most importantly, the program expedites evaluation, optimizes workflow, and minimizes user-introduced errors with the reliable bone age calculator and built-in report generator. The digital format may also be available for integration with your Radiology Information System (RIS) for further workflow enhancement.Given the broad application of pediatric bone aging, Skeletal Development of the Hand and Wrist is not only intended for practicing and training radiologists, but for all of those who employ bone age studies as part of their practice.

MRI Atlas of Pediatric Brain Maturation and Anatomy and its software application offer a concise review of normal myelin, myelination, and commonly used MR techniques. Practical points on using MRI to assess the progress of brain maturation are discussed, followed by clinically relevant summaries of normal MR appearances grouped by age. The book version contains abridged sets of normal reference MR images between preterm and 3 years of age. The software proivides immediate access to over 13,000 high resolution, normal comparison MR images of subjects ranging in age from 32 gestational weeks to 3 years. Designed as both a practical clinical resource and educational tool, the software is ideal for use at the imaging workstation where one can rapidly bring up complete sets of high quality, scrollable MR reference images with guiding annotations to ensure more accurate and clinically valuable interpretations. Suspected deviations from normal brain development or MR signal can be more confidently identified or excluded, and diagnostic errors arising from unfamiliarity with the changing MR appearances of the immature brain can be minimized.

Through 105 highly-illustrated chapters, Interventional and Endovascular Tips and Tricks of the Trade equips interventional radiologists, surgeons, and cardiologists with unique techniques for solving complex clinical problems that may arise during both vascular and non-vascular procedures. The techniques are presented as succinct steps with particular attention paid to applications, challenges, and potential pitfalls. The accessible outline format and illustrative case examples optimize learning, patient selection, and outcomes. Suggested further readings are included with each technique. The "outside-the-box" strategies presented in this volume are useful solutions to clinical challenges in the ever-evolving field of interventional medicine, with its innovative technology, devices, and procedures.
