Book Description
Pulmonary embolism (PE) is an extremely common and highly lethal condition that is a leading cause of death in all age groups. Over the past 10 years, computed tomography (CT) scanners have gained acceptance as a minimally invasive method for diagnosing PE. In this book, a framework for computer-aided diagnosis of PE in contrast-enhanced CT images is presented. It consists of a combination of a method for segmenting the pulmonary arteries (PA), emboli detection methods as well as a scheme for evaluating their performances. The segmentation of the PA serves one of the clot detection methods, and is carried out through a region growing method that makes use of a priori knowledge of vessel topology. Two different approaches for clot detection are proposed: the first one performs clot detection by analyzing the concavities in the segmentation of the pulmonary arterial tree. It works in a semi-automatic way and it enables the detection of thrombi in the larger sections of the PA. The second method does not make use of PA segmentation and is thus fully automatic, enabling detection of clots farther in the vessels. The combination of these methods provides a robust detection technique that can be used as a safeguard by radiologists, or even as preliminary computer-aided diagnosis (CAD) tool. The evaluation of the method is also discussed, and a scheme for measuring its performance is proposed, including a practical approach to making reference detection data, or ground truths, by radiologists.

Book Description
The fourth edition of this well-received book offers a comprehensive update on recent developments and trends in the clinical and scientific applications of multislice computed tomography. Following an initial section on the most significant current technical aspects and issues, detailed information is provided on a comprehensive range of diagnostic applications. Imaging of the head and neck, the cardiovascular system, the abdomen, and the lungs is covered in depth, describing the application of multislice CT in a variety of tumors and other pathologies. Emerging fields such as pediatric imaging and CT-guided interventions are fully addressed, and emergency CT is also covered. Radiation exposure, dual-energy imaging, contrast enhancement, image postprocessing, CT perfusion imaging, and CT angiography all receive close attention. The new edition has been comprehensively revised and complemented by contributions from highly experienced and well-known authors who offer diverse perspectives, highlighting the possibilities offered by the most modern multidetector CT systems. This book will be particularly useful for general users of CT systems who wish to upgrade and enhance not only their machines but also their knowledge.

Book Description
This open access book focuses on diagnostic and interventional imaging of the chest, breast, heart, and vessels. It consists of a remarkable collection of contributions authored by internationally respected experts, featuring the most recent diagnostic developments and technological advances with a highly didactical approach. The chapters are disease-oriented and cover all the relevant imaging modalities, including standard radiography, CT, nuclear medicine with PET, ultrasound and magnetic resonance imaging, as well as imaging-guided interventions. As such, it presents a comprehensive review of current knowledge on imaging of the heart and chest, as well as thoracic interventions and a selection of "hot topics". The book is intended for radiologists, however, it is also of interest to clinicians in oncology, cardiology, and pulmonology.

Book Description
This is the ideal resource for all those requiring an authoritative and up-to-date review of imaging appearances of diseases of the lung, pleura and mediastinum. Chest radiography and CT are integrated with other imaging techniques, including MRI and PET, where appropriate. The clinical and pathologic features of different diseases are provided in varying degrees of detail with more in depth coverage given to rarer and less well understood conditions. A single volume, comprehensive reference text on chest radiology.Provides in a single resource all of the information a generalist in diagnostic radiology needs to know. Concisely and clearly written by a team of 4 internationally recognized authors.Avoids the inconsistency, repetition, and unevenness of coverage that is inherent in multi-contributed books. Multimodality coverage integrated throughout every chapter.All of the applicable imaging modalities are covered in a clinically relevant, diagnostically helpful way. Approximately 3,000 high quality, good-sized images.Provides a complete visual guide that the practitioner can refer to for help in interpretation and diagnosis. Covers both common and uncommon disorders.Provides the user with a single comprehensive resource, no need to consult alternative resources. Access the full text online and download images via Expert Consult Access the latest version of the Fleischner Society's glossary of terms for thoracic imaging. Outlines, summary boxes, key points used throughout.Makes content more accessible by highlighting essential information. Brand new color images to illustrate Functional imaging techniques.Many of the new imaging techniques can provide functional as well as anatomic information. Introduction of a second color throughout in summary boxes in order to better highlight key information. There’s a wealth of key information in the summary boxes—will be highlighted more from the narrative text and will therefore be easier to access. Practical tips on identifying anatomic variants and artefacts in order to avoid diagnostic pitfalls.Many misdiagnoses are the result of basic errors in correlating the anatomic changes seen with imaging to their underlying pathologic processes. Latest techniques in CT, MRI and PET as they relate to thoracic diseases. The pace of development in imaging modalities and new applications/refined techniques in existing modalities continues to drive radiology forward as a specialty. Emphasis on cost-effective image/modality selection.Addresses the hugely important issue of cost-containment by emphasizing which imaging modality is helpful and which is not in any given clinical diagnosis. COPD and Diffuse Lung Disease, Small Airway disease chapters extensively up-dated.

Book Description
This book is a comprehensive review of pulmonary embolism (PE) which, with deep vein thrombosis, is assigned to the term venous thromboembolism (VTE) and currently the third most frequent acute cardiovascular syndrome globally. In the past decade we have seen a remarkable improvement in new diagnostic tools as well as novel therapeutic options to manage patients with VTE and this book provides a thorough clinical discussion of the diagnosis and management of these patients. Pulmonary Embolism presents a comprehensive review of all aspects of the epidemiology, pathophysiology, diagnosis, risk assessment and therapeutic options to manage the patient with PE. To aid healthcare providers caring for patients with acute PE, it encapsulates a novel, comprehensive, yet simple, pathway for the management of patients with PE, which can be used in many health care systems around the globe. This pathway is at the core of the book and all chapters are related to this unique algorithm.
