This book comprehensively highlights modern emergency radiology diagnosis of the acute abdomen. In traumatic as well as non-traumatic emergencies, the clinical term "acute abdomen" refers to a variety of serious conditions in an often progressive clinical situation that call for an immediate diagnostic and therapeutic intervention. Today, thorough and rapid diagnostic radiological imaging is broadly available and the radiologist has gained a central role in patient handling in many emergency medicine departments. In addition to proficient radiological knowledge, communication and close co-operation among the various specialists involved are essential for successful patient management. Emergency radiologists must not only acquire a full understanding of the imaging modalities and technical requirements, but they should also have appropriate clinical knowledge of the various disorders in order to become valuable contributors to the therapy decision-making process. Emergency Radiology of the Abdomen provides a comprehensive review of the etiology, pathophysiology, and clinical presentation of acute abdominal conditions, both after traumatic events and in the non-traumatic setting. It focuses on imaging features and high-end emergency radiology that are indispensable for a timely management approach. Numerous high-quality images, diagrams, and easy-to-read tables are provided.

This is the first textbook of its kind devoted to describing the biological complexities of breast cancer in a way that is relevant to the radiation oncologist. Radiation Oncology has long treated breast cancer as a single biological entity, with all treatment decisions being based on clinical and pathologic risk factors. We are now beginning to understand that biological subtypes of breast cancer may have different risks of recurrence as well as different intrinsic sensitivity to radiotherapy. Multi-gene arrays that have for years been used to predict the risk of distant recurrence and the value of systemic chemotherapy may also have utility in predicting the risk of local recurrence. Additionally, the targeted agents used to treat breast cancer may interact with radiotherapy in ways that can be beneficial or undesirable. All of these emerging issues are extensively discussed in this book, and practical evidence-based treatment recommendations are presented whenever possible.

Female genital malformations represent miscellaneous deviations from normal anatomy. With a prevalence of approximately 6% in the general population, they might be associated with health problems, potentially dangerous complications or poor reproductive outcome depending on the type and the degree of the anatomical abnormality. During the last two decades the better understanding of their pathogenesis, the availability of new non-invasive techniques for their diagnosis and the increased experience from their treatment have radically changed their management. A new, clinically oriented classification system has now been developed facilitating their evidence-based appraisal. It is a reality that the management of female genital malformations has changed rapidly during the last few years from an experience based and mainly descriptive field to a scientific evidence-based one. This book presents all uterine, cervical and vaginal anomalies in a systematic way and the new ESHRE/ESGE classification system utilised for their categorization. In addition, their embryogenesis and etiology are summarized. The diagnostic work-up of women with female genital malformations is reviewed in an evidence-based fashion and taking into account the availability of new non-invasive diagnostic methods. The treatment strategy and the therapeutic alternatives to restore health and reproductive problems associated with their presence are critically reviewed.

In the new era of functional and molecular imaging, both currently available imaging biomarkers and biomarkers under development are expected to lead to major changes in the management of oncological patients. This well-illustrated two-volume book is a practical manual on the various imaging techniques capable of delivering functional information on cancer, including preclinical and clinical imaging techniques, based on US, CT, MRI, PET and hybrid modalities. This first volume explains the biophysical basis for these functional imaging techniques and describes the techniques themselves. Detailed information is provided on the imaging of cancer hallmarks, including angiogenesis, tumor metabolism, and hypoxia. The techniques and their roles are then discussed individually, covering the full range of modalities in clinical use as well as new molecular and functional techniques. The value of a multiparametric approach is also carefully considered.
Most ingested foreign bodies pass through the gastrointestinal tract without a problem. However, both ingested and inserted foreign bodies may cause bowel obstruction or perforation or lead to severe hemorrhage, abscess formation, or septicemia. Foreign body aspiration is common in children, especially those under 3 years of age, and in these cases chest radiography and CT are the main imaging modalities. This textbook provides a thorough overview of the critical role of diagnostic imaging in the assessment of patients with suspected foreign body ingestion, aspiration, or insertion. A wide range of scenarios are covered, from the common problem of foreign body ingestion or aspiration in children and mentally handicapped adults through to drug smuggling by body packing and gunshot wounds. Guidance is offered on diagnostic protocols, and the value of different imaging modalities in different situations is explained. Helpful management tips are also provided. This textbook will prove invaluable for residents in radiology, radiologists, and physicians who are involved on a daily basis, within an emergency department, in the management of patients with suspected ingestion, aspiration, or insertion of foreign bodies.
