ENGLISH ABSTRACT: Introduction - X-ray imaging is used to diagnose and follow up various conditions in neonates (i.e. pre-term babies and babies up to the age of 28 days). Chest anterior-posterior (AP) radiographs are used ...

ENGLISH ABSTRACT: Background: The assignment of radiation weighting factors to high energy neutron
sources is important as there is reason to believe that neutron relative biological
effectiveness (RBE) may be related ...

Background
The mechanics of the right ventricle (RV) are not well understood as studies of the RV have been limited. This is, in part, due to the RV's thin wall, asymmetric geometry and irregular motion. ...
The mucosa, being the innermost layer of the gastro intestinal tract, is intimately concerned with digestion and absorption, and, presumably, also with the transport of intestinal contents. In anatomical, physiological and ...

Two cases of rhabdomyosarcoma of the bladder are reported. These tumors mainly occur in male children. They may arise in any part of the bladder and usually cause dysuria, lower urinary tract obstruction and a palpable ...
During fluoroscopic bladder and bronchial examinations the radiation workers concerned are exposed to 90°-scattered photons. The effective energy expressed in mm Al was measured for these photons exited at tube potentials ...
In terms of regulations gazetted in 1973, the Department of Health has control of the practice of medical radiology in South Africa. The regulations and the rules of the South African Medical and Dental Council that apply ...
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 ...
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 ...

Although the ECG-gated radionuclide blood pool scan (GBPS) has become an established method for studying regional myocardial wall motion, it is usually performed with the aid of an expensive computer system. A simple, ...
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.
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 ...
Two therapeutic modalities are currently of great interest, namely photo- and radiosensitization. Whereas photosensitizers only function in combination with ultraviolet (UV) light, radiosensitizers act only in combination ...
