  cross sectional ct thorax anatomy: Classic Imaging Signs Bo Gao, Alexander M. McKinney, 2020-11-06 This book systematically summarizes classic imaging signs' characteristics and theory for whole body imaging, serving as a clinical guide for the understanding, prevention, and diagnosis of miscellaneous entities. In recent years, with the rapid evolution of modern imaging modalities, radiology has secured an irreplaceable role in diagnosis within standard clinical practice and being familiar with radiological signs has become essential. The book provides a multimodality review of more than 300 commonly utilized radiologic signs in radiography, CT, MRI, US, angiography, and nuclear medicine, including PET-CT. It is designed to enhance recognition of specific imaging patterns and enable the image interpreter to confidently reach an accurate diagnosis. Divided into ten chapters dedicated to different anatomic areas, each sign includes detailed discussion that explains the history and meaning of the descriptive or metaphoric sign, alongside illustrative photos for memory aid and clarification. Uniquely written from a practical point of view, each case leads you through a radiology expert’s thought process in analyzing the classic signs with considerations of common misinterpretations and imaging pitfalls. The cases then highlight clinical presentation, relevant pathology, anatomy, physiology, and pertinent imaging features of common disease processes. Key information is distilled into succinct, bulleted points with detailed illustrations and images. This book is an ideal reference and review for practicing radiologists, as well as trainees preparing for licensing examinations.

  cross sectional ct thorax anatomy: See Right Through Me Savvas Andronikou, 2012-12-04 This atlas demonstrates all components of the body through imaging, in much the same way that a geographical atlas demonstrates components of the world. Each body system and organ is imaged in every plane using all relevant modalities, allowing the reader to gain knowledge of density and signal intensity. Areas and methods not usually featured in imaging atlases are addressed, including the cranial nerve pathways, white matter tractography, and pediatric imaging. As the emphasis is very much on high-quality images with detailed labeling, there is no significant written component; however, ‘pearl boxes’ are scattered throughout the book to provide the reader with greater insight. This atlas will be an invaluable aid to students and clinicians with a radiological image in hand, as it will enable them to look up an exact replica and identify the anatomical components. The message to the reader is: Choose an organ, read the ‘map,’ and enjoy the journey!
  cross sectional ct thorax anatomy: Pulmonary Functional Imaging Yoshiharu Ohno, Hiroto Hatabu, Hans-Ulrich Kauczor, 2020-12-11 This book reviews the basics of pulmonary functional imaging using new CT and MR techniques and describes the clinical applications of these techniques in detail. The intention is to equip readers with a full understanding of pulmonary functional imaging that will allow optimal application of all relevant techniques in the assessment of a variety of diseases, including COPD, asthma, cystic fibrosis, pulmonary thromboembolism, pulmonary hypertension, lung cancer and pulmonary nodule. Pulmonary functional imaging has been promoted as a research and diagnostic tool that has the capability to overcome the limitations of morphological assessments as well as functional evaluation based on traditional nuclear medicine studies. The recent advances in CT and MRI and in medical image processing and analysis have given further impetus to pulmonary functional imaging and provide the basis for future expansion of its use in clinical applications. In documenting the utility of state-of-the-art pulmonary functional imaging in diagnostic radiology and pulmonary medicine, this book will be of high value for chest radiologists, pulmonologists, pulmonary surgeons, and radiation technologists.

  cross sectional ct thorax anatomy: MRI of the Lung Hans-Ulrich Kauczor, 2008-11-12 During the past decade significant developments have been achieved in the field of magnetic resonance imaging (MRI), enabling MRI to enter the clinical arena of chest imaging. Standard protocols can now be implemented on up-to-date scanners, allowing MRI to be used as a first-line imaging modality for various lung diseases, including cystic fibrosis, pulmonary hypertension and even lung cancer. The diagnostic benefits stem from the ability of MRI to visualize changes in lung structure while simultaneously imaging different aspects of lung function, such as perfusion, respiratory motion, ventilation and gas exchange. On this basis, novel quantitative surrogates for lung function can be obtained. This book provides a comprehensive overview of how to use MRI for imaging of lung disease. Special emphasis is placed on benign diseases requiring regular monitoring, given that it is patients with these diseases who derive the greatest benefit from the avoidance of ionizing radiation.
