[Reduction of doses in teleradiography of the spine. Criteria of radiation protection and studies of dosimetry].

To reduce the radiation exposure during full spine X-ray examinations, the following techniques were instituted: 72" tube to film distance; X-ray beam collimation; fast screen-film combination (rare earth gradual screens with high speed films); additional compensation filters; shielding of the most radiation-sensitive organs. Dosimetric measurements are reported. A very high reduction in exposure, above all of breasts and gonads, was obtained, without significant loss in the quality of radiographs.

[Renal tubular damage after rapid intravenous contrast study with iopamidol].

Reference is made to results obtained in 53 nephropathics in the study of urinary elimination of alphaglycosidase and lysozyme before and after rapid contrastography with sodium and meglumine diatrizoate and with iopamidol. A statistically significant difference in alphaglycosidase was evident with both media, whereas no change was noted for lysozyme. As far as the evaluation of alphaglycosidase was concerned, the tubular alteration induced by each medium was the same in terms of statistical comparison of the mean differences before and after urography.

[Nephrangiotomography with iopamidol in renal insufficiency].

An account is given of a study of 118 patients, including 67 with renal failure of varying severity, examined nephrangiotomographically with the aid of both a non-ionic contrast medium (iopamidol) and a conventional medium (sodium diatrizoate and methylglucamine). It is shown that the advantages presented by rapid injection of the medium, and the obtaining of prompt vascular data, are accompanied by those offered by the non-ionic medium, since it induces reduced osmotic diuresis, which permits satisfactory visualisation of the excretory ducts, even in patients with very low glomerular filtration values.

[Heterotropic hepatobiliary (and intestinal) elimination of uroiodate contrast medium in patients with Lightwood-Albright nephrocalcinosis].

Incidental hepatobiliary elimination of a urophilous preparation in a subject with nephrocalcinosis is referred to in an examination of the question of heterotopic opacisation. Stress is placed on the link between this phenomenon with coincident renal insufficiency, and on the need for lengthy controls to ensure its demonstration.
