Diagnostic imaging of the chest/ Dag Wormanns.

Revised English translation of the first German edition of Thoraxdiagnostik / Dag Wormanns. Stuttgart : Georg Thieme Verlag, [2017].Includes bibliographical references and index."Due to the remarkable concentration of various vital organs that can be visualized in thoracic imaging, the region occupies a firm central place in the spectrum of diagnostic imaging. The book is based on the contents of the curriculum for thoracic imaging of the European Society of Radiology and covers the gamut of issues in thoracic imaging that radiologists are faced with in their daily clinical practice. Contents are divided into four main sections: fundamentals of diagnostic thoracic imaging, diseases of the chest and special findings, differential diagnostic considerations and incidental findings, and glossary. Key Features: Full coverage of all disease entities as they affect the lungs, airways, pleura, mediastinum, thorax wall and diaphragm, thoracic arteries and veins, and the heart All imaging modalities are covered in detail: projection radiography, fluoroscopy, ultrasound, CT, and MRI, as well as digital image postprocessing Subsections concentrate on the more critical findings, such as pulmonary nodules and cavitary lesions Special section on occupational pulmonary diseases Congenital malformations of the thorax, and much more Diagnostic Imaging of the Chest is an essential reference guide for radiologists, both in training and in practice"--Examination Technique -- Basic Anatomy -- General Symptomatology -- Indications -- Pneumonia -- Diffuse Parenchymal Lung Diseases -- Immunologic Diseases of the Lung -- Chronic Obstructive Pulmonary Disease -- Tumors of the Lung -- Airway Diseases -- Pleural Diseases -- Mediastinal Diseases -- Diseases of the Chest Wall and Diaphragm -- Vascular Diseases -- Chest Trauma -- Diagnostic Imaging of the Chest in Intensive Care Medicine -- Treatment-Related Changes -- Occupational Lung Diseases -- Congenital Thoracic Diseases and Malformations -- Nonvascular Interventions -- Pulmonary Nodules -- Cavities -- Persistent or Migratory Pulmonary Infiltrates -- Diagnostic Schema for Typical Computed Tomography Findings of Diffuse Pulmonary Diseases -- Fleischner Society Glossary of Terms for Thoracic Imaging.1 online resourc

Enhanced vertebra to disk ratio as a new semi-quantitative imaging biomarker for Gaucher disease patients

Purpose: Gaucher disease (GD) is an inherited lysosomal storage disorder. The Vertebral Disk Ratio (VDR) is a semi-quantitative imaging biomarker designed to diagnose and monitor GD. Computed from standard T1 MRI images, the VDR is derived from 2D segmentations. This study aimed to evaluate the 3D version of VDR, namely eVDR, and analyze the performances of two eVDR–derived response criteria for GD patients. Methods: Three datasets were used: 8 longitudinal GD patients, 13 non-GD patients, and 2 longitudinal GD patients with known Bone Marrow Burden (BMB) scores. Two eVDR-derived response criteria were tested: 1) a parametric version (PeVDR) averaging all eVDR measures recorded for the 5 lumbar vertebrae; and 2) a non-parametric version (NPeVDR), considering all eVDR measures as independent and evaluating therapeutic response in a paired fashion. Analyses included assessment of reader variability in eVDR (3D) versus VDR (2D) and comparison with BMB response criteria. Results: The repeatability of eVDR (3D) versus VDR (2D) demonstrated no difference in mean values but a lower variance (p < 0.004). The PeVDR intra-reader variability had a standard deviation < 0.1 with a coefficient of variation < 5%; the inter-reader variability featured a Limit of Agreement < 5% and a Bias < 3%. Observational comparison of eVDR and BMB scoring and sensitivity indicated a correlation between PeVDR and BMB, with an improved sensitivity with the NPeVDR version. Conclusions: Based on a standard MRI sequence, the eVDR imaging biomarker and its derived response criteria improved GD assessments and could help assessing other bone marrow diseases

Joint Statement of the German Radiological Society and the German Respiratory Society on a Quality-Assured Early Detection Program for Lung Cancer with Low-Dose CT

Substantial new data on the early detection of lung cancer with low-dose CT has become available since the last joint statement of the German Radiological Society and the German Respiratory Society was published in 2011. The German S3 guideline on lung cancer was revised in 2018 and now contains a weak recommendation regarding the early detection of lung cancer with low-dose CT in a quality-assured early detection program. These new developments required a change in the position of the involved professional societies. This joint statement describes the main features of a quality-assured program for the early detection of lung cancer with low-dose CT in Germany

Recommendations of the Thoracic Imaging Section of the German Radiological Society for clinical application of chest imaging and structured CT reporting in the COVID-19 pandemic

This information provided by the Thoracic Imaging Section of the German Radiological Society is intended to give physicians recommendations on the use of thoracic imaging procedures in the context of the current COVID-19 pandemic. It represents the consensus of the authors based on the previous scientific knowledge and is intended to provide guidance for unified, structured CT reporting if COVID-19 pneumonia is suspected. The recommendations presented correspond to state of knowledge at the time of print and will be updated according to the results of ongoing and future scientific studies.
