Introduction: The Republic of Korea has developed a national standard based on which diagnostic X-ray equipment must be tested every 3 years. Accordingly, the performance of X-ray equipment used in all hospitals is evaluated by national certification bodies in compliance with the safety management regulations for X-ray equipment. However, if the equipment i...

Background: There is not any report on the radiation doses received by patients in diagnostic radiology sections in hospitals under control of Chaharmahal and Bakhtiari Medical Sciences University, in the south west of Iran. Objectives: The aim of this study is measurement of entrance surface doses (ESD) for the most routine types of X-ray procedures in radiology centers as part of ongoing d...

background: radiation dose knowledge through xray examinations and their distribution in iran provides useful guidance on patient dose reduction. the results of the entrance skin dose (esds) of five common radiographies in all radiology centers in yazd province were reported in our previous study (2003). in the present study we have evaluated the collective effective dose of conventional x-ray ...

As children are prone to be more radiosensitive than adults, it is imperative assess the Entrance Skin Doses (ESDs) for patients being examined by X-rays, in order ensure optimization of dose while considering a number other fickles. The ESD received 50 paediatrics (aged 1-13 years) undergoing 8 types X-ray examinations were measured at Federal Teaching Hospital, Ido-Ekiti, Ekiti, Nigeria, with...

Background: People occasionally undergo medical diagnostic X-ray examinations and expose their red blood cells to radiation. Radiation that is generated from medical diagnostic X-ray machines is widely used in medical diagnoses. One of the important parameters is kilo-voltage (kV) that is applied across the X-ray tube in medical diagnostic X-ray machines. Kilo-voltage influences the radiation d...

Application of diagnostic X-ray examination to pregnant women is complicated since risks to both mother and embryo/fetus must be considered. Embryos and fetuses are more sensitive to radiation than adults or children. The threshold doses for fetal death, malformations and mental retardation which are deterministic effects, are reported to be 100-200 mGy or higher. The relative risk for childhoo...

The aim of this study was to evaluate the frequency of specific diagnostic methods used for diagnosis of oral pathologies. The sample consisted of 198 patients (98 man and 100 women) with formulated diagnosis, confirmed postoperatively by histopathological verification. In 74.7% of subjects only X-ray diagnostic examination was used. Both X-ray and computed tomography (CT) examinations were use...

introduction: rapid diagnosis of traumatic intrathoracic injuries leads to improvement in patient management. this study was designed to evaluate the diagnostic value of chest radiography (cxr) in comparison to chest computed tomography (ct) scan in diagnosis of traumatic intrathoracic injuries. methods: participants of this prospective diagnostic accuracy study included multiple trauma patient...
