BACKGROUND AND OBJECTIVE Chest X-ray is recommended for routine use in patients with suspected pneumonia, but its use in emergency settings is limited. In this study, the diagnostic performance of a new method for quantitative analysis of lung ultrasonography was compared with bedside chest X-ray and visual lung ultrasonography for detection of community-acquired pneumonia, using thoracic compu...

The harmful effects of ionising radiation are widely acknowledged. It has been reported that young children, particularly girls, have a higher sensitivity to radiation than adults. However, the exact detrimental effects of radiation, particularly at the low doses used in routine diagnostic radiography, are unknown and the subject of much controversy. Computed tomography (CT) accounts for about ...

Chest radiology traditionally consists of plain chest x-rays and computed tomography examinations, or so it was a decade ago. New modalities and developments in techniques now require a more comprehensive functional and structural approach to imaging the chest, which should include assessment of all its contents (the term is cardiothoracic radiology) as well as application of PETCT, MRI and, in...

We report here the results of a dose evaluation based on information obtained in a 2011 questionnaire as compared with an investigation made in 2007. Briefly, in general radiography, the dose used in most examinations in 2011 was lower than in 2007. However, since the entrance surface dose for chest X-rays showed an increase, there is a need to standardize the taking of digital images to be abl...

Introduction: Nowadays ionizing radiation has a considerable contribution in medical diagnostic and treatment. Using ionizing radiation is increasing rapidly, so biological effects of ionizing radiation should be considered more. X-rays in the range of diagnostic radiology have hazardous effects and risks that are defined as random effects. These effects obey the LNT hypothesis that occur at lo...

  Background: The sporadic cases of radiation-activated multiple sclerosis (MS) has been previously described, with a few studies focused on the relationship between radiation and the risk of MS. The aim of our study was to evaluate the association between history of X-ray radiation and MS.   Methods : This case-control study was conducted on 150 individuals including 65 MS patients and 85 age-...

Introduction Chest radiographs are the most frequent diagnostic tests that are performed with X-ray in an intensive care unit (ICU). The riskthatthestaffperceives from these examinations produces the evictionof the room during the examination to avoid potential exposure, with a consequent impairment of the quality of care offered to patients. We do not knowhow widespread this practiceactually is.

The concept of diagnostic reference levels (DRLs) is recognised as an efficient and powerful tool in optimization of diagnostic X-ray examinations. Norway was one of the pioneer countries in establishing national DRLs, but focus on implementation and use of DRLs locally at the clinics in optimization purposes has been absent until now. The aim of this study was to map the dose levels and optimi...

Chest radiography is the most commonly performed diagnostic X-ray examination. The radiation dose to the patient for this examination is relatively low but because of its frequent use, the contribution to the collective dose is considerable. Consequently, optimization of dose and image quality offers a challenging area of research. In this article studies on dose reduction, different detector t...
