| Popis: | The use in Switzerland of three chest X-ray imaging modalities is studied. The frequency and dosimetric aspects associated with chest radiography, chest CT, and photofluorography are investigated and the Swiss figures are compared with those of other countries. The frequencies are established by means of a nationwide survey performed in 1998, whereas the doses are determined by modelling, based on the technical parameters of the examinations. The annual frequencies of chest radiography, chest CT, and photofluorography are 201, 7, and 7 per thousand population, respectively. The standard effective doses related to these three types of examinations are 0.057, 9, and 0.13 mSv, respectively. The collective dose associated with chest X-ray imaging amounts to 606 man.Sv, representing 8.5% of the total collective dose due to diagnostic and interventional radiology. The geographic and seasonal variations, as well as the distribution with the medical specialty and with the age of the patient, are established. The Swiss results compare well with the average data published in the literature for other countries of similar health care level. Chest radiography shows a significant decrease with time. It dropped by a factor of 2 in 20 years. The conformity of the indication of chest X-ray modalities with referral guidelines is also investigated. |
