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)
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.
An approach to the recognition of lesions on chest radiographs is outlined. Four basic groups of abnormalities by means of which lesions can be recognized are mentioned and are briefly described, namely an opacity, an area of increased translucency, a combination of an opacity and an area of increased translucency, and, especially, an alteration in normal… (More)
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.
A 16-year-old girl had had a splenic abscess for approximately 20 months with minimal symptoms and signs. Progressive elevation of the left hemidiaphragm could be traced on chest radiographs from 20 months before admission, and was shown on ultrasonography, radionuclide scintigraphy and computed tomography to be secondary to massive splenomegaly. The… (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)
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.
