摘要:

Miss K. Christmas recently presented the Institute's Library with some mementoes of her grandfather, Mr. Richard Kerr, who gave lectures to the public on X rays and other scientific subjects in the early years of this century. In the days before radio and television, and when organized “adult education” was overwhelmingly vocational, such lectures were one of the principle means of spreading knowledge of the latest scientific discoveries as well as a popular form of entertainment.

摘要:

AbstractStomach involvement is rare in American Burkitt's lymphoma. Three cases were noted in 66 patients, and all were associated with large left upper quadrant masses. The appearance of Burkitt's lymphoma of the stomach is similar to other lymphomas and consists of diffuse infiltration of the wall, mucosal thickening, ulcerations, and intra- and extragastric masses. Extension into the oesophagus was noted twice, and small bowel masses were associated with two cases. CT scanning and ultrasound are useful for defining extragastric extent of tumour. Rapid reversion to a more normal appearance is noted following chemotherapy.

摘要:

It is possible to argue that the radiologist's main purpose is to ensure that the work coming from a radiology department is of the highest possible standard. This entails personally, or through a deputy, making sure that each step contributing to the finished product is made with care and thought, from considering whether it is in the patient's best interest to be examined to the choice of film, screens, equipment, preparation, procedure, processing, viewing, diagnosis and reporting.

摘要:

AbstractMammograms were obtained from 44 women aged over 30 years with bilateral primary breast cancer, 60 women with unilateral breast cancer, matched for age and menopausal status with the bilateral cases, and 937 normal women, again all aged over 30 years. The mammograms were classified according to Wolfe's criteria. Both groups of cancer patients were found to have a significantly (p<0.05) greater proportion of pre-menopausal women with the DY type of breast parenchymal pattern compared with the normal pre-menopausal women. No association was found between the P2mammographic pattern and breast cancer. The study failed to show any difference in the distribution of mammographic risk categories in women with bilateral disease and those with unilateral cancers only.

摘要:

AbstractThe effects of radiological contrast media on red cell morphology and rigidity have been studied. It has been shown that all the contrast agents studied, even when iso-osmolar with plasma, produce changes in red cell morphology, revealing the intrinsic chemotoxicity of contrast medium molecules. The changes are greatest with the most strongly protein-bound medium investigated—meglumine ioglycamide. The effects on red cell rigidity, on the other hand, appear purely a function of osmolality, being entirely reproducible with hyperosmolar solutions of saline. At concentrations isoosmolar with plasma no effect on deformability is observed. Since the increased rigidity of red cells induced by contrast medium adversely affects blood flow, the use of the new low-osmolality contrast media is particularly recommended in pulmonary angiography and renal arteriography.

摘要:

This book describes in great detail the use of different vasoactive drugs for the enhanced demonstration of tumours by angiography in experimental laboratory animals and in clinical practice. It is liberally illustrated with subtraction angiograms, tables and colour photographs of pathological specimens, and there is a large and comprehensive bibliography on the subject of pharmacoangiography.

摘要:

AbstractWe have found that iopamidol 370 mg I/ml solutions may be greatly supersaturated and iopamidol 300 mg I/ml solutions slightly supersaturated at 4°C and at 25°C. The solubility and degree of supersaturation probably depend on the isomeric purity of the preparation. Some possible implications are discussed.

摘要:

This classic German text book of neuroradiology now appears in its first English edition. The translation is good and the clear and concise text is very readable. The approach to radiological diagnosis is based on descriptions of neuropathology which are supplemented by excellent drawings.

摘要:

AbstractThe aim of this study was to demonstrate a method which could be used to identify factors which contribute to the radiation exposure to patients from fluoroscopy during contrast examinations of the gastro-intestinal tract. Measurements of exposure made at the level of the X-ray tube collimator were extrapolated to obtain entrance exposure at the centre of the field and used as an index of the integral dose to the patient. Such data have heretofore been unavailable. The population studied included 65 patients ranging in age from 1 month to 21 years. In an initial study, median entrance exposure at the field centre for barium swallow examinations ranged from 0.98 to 1.7 mC/kg (3.8 to 6.6 R); barium meal: 1.9–5.7 mC/kg (7.4–22 R); barium meal with small bowel: 1.4–7.7 mC/kg (5.3–30 R); barium enema: 0.93–7.7 mC/kg (3.6–41 R). Gonadal dose, measured in males, ranged from undetectable to 0.71 mGy (71 mrad). The presence of contrast medium in the fluoroscopic field increased the exposure from a single 100 mm spot film, taken with automatic exposure control, by a factor of up to 16, and fluoroscopic exposure rate, using automatic brightness control, by a factor of 2 or more. We recommend modifications in the operation and design of fluoroscopic equipment, especially when fitted with brightness and exposure controls, for the reduction of patient exposure. Implementation of two modifications, a high/low dose switch, and a variable aperture iris diaphragm, reduced patient exposure from 1.4 to 3.4 times.

摘要:

This book is based upon a workshop held in Maryland, USA. We are not told the title of the workshop, nor its date. Judging from the references, the meeting would appear to have been in late 1979 or early 1980, and was presumably a forum for interested parties to discuss their own hypotheses concerning the future developments in this field.
