Abstract
Radiation dose measurements suggest that patients undergoing extensive neuroradiological investigations may receive a corneal dose in excess of 60 rads in tissue over a relatively short period. — There is no direct evidence that lens damage occurs in man at this level but it is important that high dose levels should be appreciated and measures taken to reduce them. Protective spectacles have been devised to effect such a reduction in two high dose procedures, namely petrous tomography and cerebral angiography, without degradation of the radiographic image. La dosimétrie permet d'admettre que la cornée reçoit plus de 60 Rads dans un temps relativement court lors d'examens neuroradiologiques. On ne peut toutefois pas affirmer qu'il en résulte une lésion cornéenne. L'auteur propose néanmoins de protéger les yeux lors d'examens comprenant une dose élevée et plus spécialement dans l'angiographie cérébrale et la tomographie du rocher. Die Messung der Strahlendosis hat gezeigt, daß Patienten während ausführlicher neuroradiologischer Untersuchungen eine Dosis im Bereich der Linse von 60 Rad in relativ kurzer Zeit erhalten. Dies bedeutet, daß Schutzmaßnahmen getroffen werden sollten, die zu einer Reduzierung der eingestrahlten Dosis führen.Keywords
