Simple tests of lung function may be misleading in the assessment of patients with interstitial lung disease. Eight patients are described with cryptogenic fibrosing alveolitis (histologically proven in four) with severe breathlessness and low gas transfer (median DLCO 32.4%, range 9.2 to 35.3%, % predicted) in whom lung volumes were preserved [median VC(More)
Systemic sclerosis is frequently complicated by fibrosing alveolitis although clinical and radiological abnormalities are not usually apparent until the lung disease is well established. The aim of this study was to investigate pulmonary involvement in systemic sclerosis by thin section CT scan, bronchoalveolar lavage (BAL) and 99mTc-DTPA clearance studies,(More)
High resolution computed tomography of the lungs was performed in three patients with the yellow nail syndrome to detect bronchiectasis. Standard CT was performed in a fourth patient. Evidence of bronchiectasis with bronchial wall thickening and bronchial dilatation was observed in all four patients. High resolution CT is a non-invasive method for detecting(More)
Twelve patients with chronic airflow limitation and 12 patients with a histological diagnosis of fibrosing alveolitis were studied. The calculated mean (SD) tissue volume of a single lung at total lung capacity was 467 (91) ml in the patients with alveolitis, which was 43% (14%) more than predicted for healthy people of the same age, sex, and height. The(More)
The assessment of bullous lung disease with respect to possible surgical treatment requires anatomical and functional information about the extent of disease and the mechanism of symptom production. It is also important to measure the function of non-bullous lung and to make some prediction of the behaviour of non-bullous lung after resection of bullae. We(More)
Diffuse lung disease is often a difficult clinical and radiographic problem to resolve. Standard computed tomography (CT) techniques are often unhelpful. By combining practical physiological criteria with narrow section CT a protocol has been developed which yields more accurate information and is now the standard method of CT investigation of diffuse lung(More)
Fifteen adults with obliterative bronchiolitis (OB) were investigated with computed tomography (CT). CT was considered to be abnormal in 13/15 patients (87%) showing widespread areas of increased attenuation of a patchy nature and variable proportion. CT revealed more extensive changes than the chest radiograph or bronchogram. It is a non-invasive(More)
Computed tomography and lung function tests were performed on 43 patients who had evidence on the chest radiograph suggesting bullous emphysema. After computed tomography scan two groups of patients could be identified. Twenty patients had generalised emphysema, which was locally worse in the area of the suspected bulla; and 23 had well defined bullae,(More)
Deep brain stimulation (DBS) electrodes have been used effectively to perform radiofrequency lesions in the brain. This study aimed to characterize lesion geometry and peak tissue temperature achieved when lesioning through DBS electrodes. Fresh bovine liver was chosen for a medium as the tissue reliably changes color between 45 and 50 °C. Medtronic 3387(More)
Cerebral aneurysms are rare in the pediatric population, making a definitive treatment algorithm difficult. Microsurgical clipping is the first choice for treatment but is not always feasible, while high recurrence rates and radiation exposure make endovascular options less favorable. Extracranial-intracranial (EC-IC) bypass, though not commonly performed(More)
