    Benadering van interpretasie van rontgenfoto's van die longe
    (HMPG, 1979-11) Beyers, J. A.
    Different approaches to the analysis of radiographs of the lungs are briefly discussed. A systematic routine is proposed, outlined and briefly motivated. It is emphasized that radiological findings must be correlated with clinical findings if meaningful conclusions are to be drawn.

    Chroniese miltabses : 'n gevalbespreking
    (Health & Medical Publishing Group, 1984) Tredoux, J. G.; Hough, F. S.; Adams, G.; Beyers, J. A.; Klopper, J. F.
    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 presence of splenic abscesses was confirmed by laparotomy and she was cured by splenectomy. The nonspecific clinical presentation and potential high mortality of this condition are stressed, and the role of diagnostic aids is discussed. Ultrasonography is a good screening procedure in terms of cost and speed, but splenic scintigraphy is more sensitive. Computed tomography is the most sensitive and specific non-invasive procedure for the diagnosis of splenic abscesses.

    Radiological features of normal and abnormal pulmonary blood flow
    (HMPG, 1979-05) Beyers, J. A.
    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 are described.

    The radiological features of primary pulmonary tuberculosis
    (HMPG, 1979-06) Beyers, J. A.
    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 investigations.

    The recognition of lesions on chest radiographs
    (HMPG, 1979-05) Beyers, J. A.
    An approach to the recognition of lesions on chest radiographs is outlined. Four basic groups of anormalities 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 radiological anatomy.
