A very brief review is given of the pathology of primary pulmonary tuberculosis. Numerous characteristic, but not pathognomonic, radiological appearances of primary pulmonary tuberculosis are briefly described and some of them are illustrated. The final diagnosis, however, depends on correlating the radiological picture with the clinical picture and special… (More)
The value of alveolar lavage as an investigative technique was determined in patients with interstitial lung disease. Alveolar cytology was related to defined histopathological degrees of disease activity found in transbronchial biopsy specimens. The degree of disease activity as assessed by these two techniques was compared with radiological evaluation.… (More)
Obstructive sleep apnea (OSA) is a common disease with high morbidity and related mortality. Narrowing and collapse of the pharyngeal airway during sleep characterize the disease, resulting in a decrease (hypopnea) or a complete cessation (apnea) of oronasal airflow. Upper airway stimulation (UAS), using electrical neurostimulation of the hypoglossal nerve… (More)
A new sign of pneumomediastinum (mediastinal emphysema), namely a visible wall of a main bronchus as seen in the mediastinum on frontal radiographs of the chest, is described. This sign was present in eight out of 20 random cases of pneumomediastinum in adolescents and adults.
A short review is given of the anatomy of the pulmonary arterial system and of the bronchial arterial system. The normal vascular pattern of the lung as well as the altered vascular pattern under a number of abnormal circumstances is described.
Conventional radiology is a routine examination in the diagnosis and management of cardiac diseases. A brief review of its value and limitations is given. A number of technical and/or physiological factors which may influence the cardiopulmonary configuration are mentioned. An approach is suggested for analysis of radiographs of the heart.
Facilities for magnetic resonance imaging (MRI) have been available in South Africa since November 1985. This article summarizes our experience with this new imaging modality, illustrates normal anatomical features and pathological conditions in sagittal, coronal and axial planes, and compares MRI with computed tomography scans of the same regions.
A clinical classification embracing most of the causes of pulmonary oedema is given, as well as a radiological classification, and the different ways in which pulmonary oedema may present radiologically are briefly described.
