Abstract Background The purpose of this study was to estimate the doses delivered to adult patients during chest examination for comparison with those elsewhere and to establish a local diagnostic reference level for the chest.
The doses delivered in the standard X-ray examinations are not sufficiently optimized and controlled. The working protocols for the same exam given differ for similar morphotypes within the same hospital structure. The analysis and processing of the data was carried out by Excel The entrance skin dose of the chest obtained in mGy was 0. Conclusion The present study allowed us to observe large variations at the entrance skin doses of the chest.
These variations have made it possible to understand that the entrance skin doses to the chest are optimized and do not exceed the proportions of those estimated by others and standards internationally.
This aspect demonstrates that the diagnostic reference levels as enumerated are dependent on the doses delivered and include not only the notions of quality of the radiographic image and the quality assurance of the radiological equipments but also the level of the manipulators trained. Go to: 1. Introduction The medical applications of ionizing radiation have, for many years now, contributed to an improvement of medical practicals and bring a real benefit in terms of health. In radiology, dosimetry and diagnostic quality of images are inseparable.
Diagnosis is a function dependent on the quality of the radiological image. Dosimetry could be defined as the measurement of ionizing radiation received or deposited in a medium [ 1 ]. Diagnostic medical examinations using ionizing radiation such as radiology, CT, and nuclear medicine lead to variable exposure of patients according to the procedure implemented, the facility of the technology, and the patient's morphotype [ 2 ]. In view of this, the reality of these risks, however, comes up against the general problem commonly referred to as the problem of low doses.
