Diagnosis and therapy planning in oncology applications often rely on the joint exploitation of two complementary imaging modalities, namely Computerized Tomography (CT) and Positron Emission Tomography (PET). While recent technical advances in combined CT/PET scanners enable 3D CT and PET data of the thoracic region to be obtained with the patient in the same global position, current image dat...
The aims of this study were to determine whether infants and toddlers with chronic lung disease of infancy (CLDI) have smaller airways and lower lung density compared with full-term healthy controls. Multi-slice computed tomography (CT) chest scans were obtained at elevated lung volumes during a brief respiratory pause in sedated infants and toddlers; 38 CLDI were compared with 39 full-term con...
A reduced exercise capacity, which limits the performance of activities of daily living and social participation, is a cardinal feature of chronic obstructive pulmonary disease (COPD). Breathlessness is the main limiting symptom, although, depending on the task undertaken [1], leg discomfort is prominent in a substantial minority of patients. Dyspnoea arises through the interplay of pulmonary m...
Emphysema is highly prevalent in patients with idiopathic pulmonary fibrosis (IPF) [1] and interstitial lung disease (ILD) associated with rheumatoid arthritis [2], conditions linked to tobacco smoking [3]. The combination of pulmonary fibrosis and emphysema (CPFE) has been suggested to be a syndrome [4, 5], based on distinctive clinical, radiological, functional and outcome features [6]. Indee...
Clinical measurements and pulmonary functions, including maximal transrespiratory pressures, were studied in 30 patients (age 43 (SD 10) years) with ankylosing spondylitis. Vital capacity (VC) was slightly reduced to 79 (16)% and forced expiratory volume in one second (FEV1) was similarly reduced to 82 (20)% such that the average FEV1/VC ratio was 77.8 (6.65). Total lung capacity was slightly r...
