[Prevention, Diagnosis, Therapy, and Follow-up of Lung Cancer - Interdisciplinary Guideline of the German Respiratory Society and the German Cancer Society - Abridged Version].

The current S3 Lung Cancer Guidelines are edited with fundamental changes to the previous edition based on the dynamic influx of information to this field:The recommendations include de novo a mandatory case presentation for all patients with lung cancer in a multidisciplinary tumor board before initiation of treatment, furthermore CT-Screening for asymptomatic patients at risk (after federal approval), recommendations for incidental lung nodule management , molecular testing of all NSCLC independent of subtypes, EGFR-mutations in resectable early stage lung cancer in relapsed or recurrent disease, adjuvant TKI-therapy in the presence of common EGFR-mutations, adjuvant consolidation treatment with checkpoint inhibitors in resected lung cancer with PD-L1 ≥ 50%, obligatory evaluation of PD-L1-status, consolidation treatment with checkpoint inhibition after radiochemotherapy in patients with PD-L1-pos. tumor, adjuvant consolidation treatment with checkpoint inhibition in patients withPD-L1 ≥ 50% stage IIIA and treatment options in PD-L1 ≥ 50% tumors independent of PD-L1status and targeted therapy and treatment option immune chemotherapy in first line SCLC patients.Based on the current dynamic status of information in this field and the turnaround time required to implement new options, a transformation to a "living guideline" was proposed.

[Arthritis and pulmonary cavities].

This case report describes the very rare simultaneous occurrence of rheumatoid arthritis and granulomatosis with polyangiitis with the only organ manifestation of life-threatening bilateral pulmonary cavities. Due to the acuteness of the vasculitis, treatment was primarily with cyclophosphamide infusions and high-dose glucocorticoids, and in the further course with high-dose methotrexate. Routine thoracic imaging also seems to be useful when conventional basic rheumatologic treatment is newly initiated, as treatment-decisive changes are seen with a relevant frequency.

[Update 2021: Pulmonary Sequelae of COVID-19 Pneumonia].

Acute COVID-19 pneumonia may result in persistent changes with various imaging and histopathological patterns, including organizing pneumonia and pulmonary fibrosis. In addition, SARS-CoV-2 infection is associated with increased risk of pulmonary vascular endothelialitis and thrombosis. Herein, current findings on pulmonary consequences of COVID-19 with implications for clinical management are summarized based on a selective literature review.

[COVID-19: A Pneumological Point of View - Long-Term Sequelae of COVID-19 - Implications For Follow-up In Respiratory Medicine].

The long-term sequelae of COVID-19 on are not yet predictable. Radiological and histopathological data on COVID-19 and observational studies after the SARS-CoV-1 pandemic 2003/2004 suggest that in a proportion of COVID-19 patients, functional limitations due to pulmonary fibrosis and other patterns of lung damage may persist. Systematic follow-up, based on prudent pulmonary function testing, is warranted for the correct diagnosis, graduation and treatment of the underlying pathology at an early stage.

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.

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.

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.

Contribution of CAD to the Sensitivity for Detecting Lung Metastases on Thin-Section CT - A Prospective Study with Surgical and Histopathological Correlation.

Purpose:  To assess the sensitivity of radiologists and a CAD system for the detection of lung metastases on thin-section computed tomographic (CT) scans prior to pulmonary metastasectomy.

Materials And Methods:  All patients scheduled for resection of lung metastases were eligible for this prospective single-center trial. 95 patients with 115 surgical procedures (pulmonary metastasectomy using thoracotomy) were included.

[Diagnostic work-up of pulmonary nodules : Management of pulmonary nodules detected with low‑dose CT screening].

Pulmonary nodules are the most frequent pathological finding in low-dose computed tomography (CT) scanning for early detection of lung cancer. Early stages of lung cancer are often manifested as pulmonary nodules; however, the very commonly occurring small nodules are predominantly benign. These benign nodules are responsible for the high percentage of false positive test results in screening studies.

[Glossary of Terms for Thoracic Imaging--German Version of the Fleischner Society Recommendations].

Unlabelled: The Fleischner Society has published several recommendations for terms for thoracic imaging. The most recent glossary was released in 2008. One glossary in German language was published in 1996.

[Management of solid pulmonary nodules].

The increasing availability of computed tomography has meant that the number of incidentally detected solitary pulmonary nodules (SPN) has greatly increased in recent years. A reasonable management of these SPN is necessary in order to firstly be able to detect malignant lesions early on and secondly to avoid upsetting the patient unnecessarily or carrying out further stressful diagnostic procedures. This review article shows how the dignity of SPNs can be estimated and based on this how the management can be accomplished taking established guidelines into consideration.

[Radiological imaging of pulmonary tuberculosis].

Pulmonary tuberculosis is now gaining increasing importance after decades of retreat. Radiological imaging plays an important role in the initial diagnosis but cannot replace bacteriological confirmation of the diagnosis. Primary tuberculosis usually presents as a primary complex consisting of a pulmonary infiltrate and hilar lymphadenopathy.

[Imaging of pneumonia].

Pneumonia represents a disease with significant epidemiological, clinical and also economical relevance. Diagnostic imaging is important for detection, differentiation and follow up of pneumonic infiltration. However morphology of pulmonary infiltration is unspecific, even with computed tomography (CT).

Reliability of a computer-aided detection system in detecting lung metastases compared to manual palpation during surgery.

For resection of lung metastases computed tomography (CT) is needed to determine the operative strategy. A computer-aided detection (CAD) system, a software tool for automated detection of lung nodules, analyses the CT scans in addition to the radiologists and clearly marks lesions. The aim of this feasibility study was to evaluate the reliability of CAD in detecting lung metastases.

Whole-body imaging of oncologic patients using 16-channel PET-CT. Evaluation of an i.v. contrast enhanced MDCT protocol.

Aim: This study evaluated a MDCT protocol for contrast-enhanced 16-channel PET-CT with regard to scan range and duration of a whole-body (18)F-FDG PET-CT examination, the occurrence of contrast-material induced artefacts and quantitative assessment of CT attenuation.

Patients, Methods: 205 patients (51.9+/-12.

Comparison of sensitivity and reading time for the use of computer-aided detection (CAD) of pulmonary nodules at MDCT as concurrent or second reader.

The purpose of this study was to compare sensitivity for detection of pulmonary nodules in MDCT scans and reading time of radiologists when using CAD as the second reader (SR) respectively concurrent reader (CR). Four radiologists analyzed 50 chest MDCT scans chosen from clinical routine two times and marked all detected pulmonary nodules: first with CAD as CR (display of CAD results immediately in the reading session) and later (median 14 weeks) with CAD as SR (display of CAD markers after completion of first reading without CAD). A Siemens LungCAD prototype was used.

Unexpected finding of elevated glucose uptake in fibrous dysplasia mimicking malignancy: contradicting metabolism and morphology in combined PET/CT.

Fibrous dysplasia is a common benign disorder of bone in which fibro-osseous tissue replaces bone spongiosa. Lesions have a typical appearance on computed tomography (CT) images and regularly show a markedly increased uptake in bone scintigraphy using (99m)Tc-labelled methylene diphosphonate ((99m)Tc-MDP) as radiotracer. The glucose avidity of these lesions depicted by positron emission tomography (PET) using the radiolabelled glucose derivative (18)F-fluoro-2-deoxy-glucose (FDG) is less well known since FDG-PET does not have a role in the assessment of this disease.

[CT-based software-supported prediction of the postoperative lung function after partial resection of the lung].

Purpose: The predicted postoperative forced exspiratory volume in one second (FEV (1)) is an important functional factor for predicting the operability of patients with bronchial carcinoma. A software tool that uses a preoperative chest MSCT and pulmonary function test (PFT) for largely automated prediction of the FEV (1) was evaluated.

Materials And Methods: Fifteen patients with surgically treated lung cancer were examined with a preoperative chest MSCT (1.
