Oncologic imaging : soft tissue tumors

This book helps readers to overcome the challenges encountered during the imaging diagnosis of soft tissue tumors due to their diversity and the significant overlap in imaging features between different tumors. It does so by fostering familiarization with typical findings and clearly explaining the pattern analysis of soft tissue tumors. The book opens with an overview of diagnostic considerations and discussion of the basic concepts of diagnostic imaging studies and histopathologic examinations. Grading and staging of soft tissue sarcomasare then described. In the second part of the book, radiologic features of soft tissue tumors are reviewed in detail, based on the 2013 WHO classification system. The third part summarizes diagnostic imaging clues, including characteristic imaging findings and radiologic signs that aid in specific diagnosis and differential diagnosis. The book closes by presenting 30 typical cases of soft tissue tumors, with questions, answers, and commentary, in order to help readers to consolidate what they have learned and to hone their diagnostic reasoning skills This book aims to provide readers with a sound understanding of the spectrum of radiologic appearances of bone tumors, which reflect histopathology, and the pattern analysis of imaging findings. The first part of the book explains basic concepts and diagnostic parameters, including demographics, lesion location, biological activity, matrix mineralization, and endosteal and periosteal reactions. In the second part, typical and atypical radiologic features of bone tumors are reviewed in detail, with emphasis on the characteristic radiographic and MR imaging findings and reference to schematic drawings and pathologic or operative images when appropriate. The third part focuses on problem solving in cases encountered in real radiology practice and identifies categorical patterns on the basis of radiographic and MR variables and lesion location. Informative cases are illustrated and compared to enhance understanding of differential diagnosis using pattern analysis. The final part of the book helps readers to consolidate what they have learned and to hone their diagnostic reasoning skills by presenting about 30 typical bone tumor cases with questions, answers, and commentary
