Interreadervarianz bei der HRCT- und CXR-Befundung in einer Längsschnittstudie bei ehemals asbeststaubexponierten Personen
… two readers evaluating high-resolution CT (HRCT) scans and x-ray scans of formerly asbestos-exposed persons. Over a period of four years, annual HRCT and x-ray scans were performed at 636 persons of a high-risk population. Each scan was evaluated by two independent experts. The x-ray …

Haben asbestassoziierte Pleuraplaques einen Einfluss auf die Lungenfunktion?
This study describes the influence of HRCT-diagnosed asbestos related pleural plaques and cumulative asbestos exposure, independently of pleural and parenchymal variances, on lung function. Furthermore the difference between the correlations of lung function to pleural plaques, diagnosed either by …

Behaviour of continuous concrete T-beams reinforced with hybrid FRP/Steel bars
… continuous hybrid reinforced concrete T-beams (HRCT). The investigations consist of three parts; the computational part, the experimental part and the finite element analysis. The computational part included two parts, the first one is developing an analytical programme using MATLAB software to …

Sex and gender in chronic obstructive pulmonary disease
… data from high resolution computed tomography (HRCT) scans. We did detect more emphysema in male smokers but there was no evidence of increased airway remodeling in women. We discuss the limits of HRCT to detect airway differences in women and men. In Chapter Four we examined the use of HRCT in …

Mechanical Signals for Compensatory Lung Growth Assessed by High Resolution Computed Tomography
… the use of high resolution computed tomography (HRCT) to understand the role of intra-thoracic mechanical force and its distribution in regenerative growth in dogs i.e. to quantify lobar lung volumes and density gradients in normal and post-pneumonectomy (following lung resection) lungs. HRCT was …

Existence of patchiness in constricted lungs : from experiments to complex system modeling
… from High-Resolution Computed Tomography (HRCT) images of the lung, the effect of longitudinal heterogeneity on resistance to airflow within central airways was studied. Lastly, the relationship between respiratory structure and function estimated from Positron Emission Tomography (PET) and …

Determinants of smoke induced lung damage and relationship with metabolic syndrome
… a whole series of measurements, including HRCT, measures of lung density/emphysema, only sputum neutrophilia (both absolute and percentage counts) predicted the annual decline in FEV1. In summary, this study suggests that there is an increased prevalence of MeS in smokers associated with …

Prognostication and disease monitoring in fibrotic interstitial lung disease
… tomography (qCT) to analyse high resolution CT (HRCT) scans may enable more accurate prognostication and disease monitoring than current routine practice. qCT work to date has identified the pulmonary vasculature as a potential radiomic biomarker to address these issues. Methods A systematic …

Early sequelae of post COVID-19 lung disease in patients who were mechanically ventilated for severe COVID-19 pneumonia
… underwent high resolution computer tomography (HRCT) of the chest, with ground glass opacities (46%) and interstitial thickening (58%) being most common. No significant risk factors for post-COVID-19 impairment were identified. Conclusion: At 3 months after hospitalization, patients who received …

Bronchiectasis in African children: disease burden, aetiology and clinical spectrum at a paediatric tertiary hospital in Cape Town, South Africa
… of bronchiectasis on plain chest radiography or HRCT reported by a paediatric radiologist. Patients with cystic fibrosis were excluded. Results Of 337 children seen during the study period, 58 (17.2%) had bronchiectasis that was diagnosed at a mean age of 34 months (SD 26). There were 32 (55.0%) …

Οι δυσπλασίες του έσω ωτός ως πρόκληση στην κοχλιακή εμφύτευση: από την απεικόνιση στη χειρουργική απόφαση και τα μετεγχειρητικά αποτελέσματα
… Η ακριβής προεγχειρητική αξιολόγηση με HRCT και MRI είναι κρίσιμη για την αναγνώριση των δυσπλασιών και την πρόληψη επιπλοκών όπως η διαφυγή εγκεφαλονωτιαίου υγρού (ΕΝΥ). Μεθοδολογία: Διενεργήθηκε εκτεταμένη βιβλιογραφική ανασκόπηση, εστιάζοντας στην ταξινόμηση των δυσπλασιών, στη …

Hochauflösende Darstellung des Innenohrs unter Anwendung zweier unterschiedlicher MRT-Sequenzen : Morphologie und pathologische Veränderungen
… precise diagnosis. In summary we can say that HRCT and MRI are not competing but are rather complementary and supplementary diagnostic methods. Important for the diagnostic reliability is the usage of thin slices (max 1 mm for the CT or in the case of MRI, under a millimetre) and high …
