The pediatric chest X-ray (CXR) provides a wealth of useful information. In most instances, clinicians are seeking more definitive information regarding the lungs. Findings can be subtle or obvious, but difficult to notice. “Tunnel vision” permits the human brain to focus on areas of interest, only to miss other important findings. This chapter discusses the clinical entities that can be identified on a pediatric CXR and presents examples of most of these entities. The CXR is best read in a methodical manner focusing one’s attention on the heart, lungs, aorta, mediastinum, bones, neck, abdomen, and the periphery of the CXR.

Majority of health institutions in Croatia do not have medical physicists in diagnostic radiology. Regarding this, in the west region of Croatia collaboration between public health institution and University Hospital Rijeka was initiated in 2015. Quality Assurance program was implemented in these public health institutions during 2015 and 2016 and the next step was to assess patient doses for the most frequent X-ray examinations. This included five public health institutions: 1 university hospital, 1 general hospital, 1 special hospital, 2 public health institutions with 13 facilities. The aim of this study was to carry out assessment of patient doses and to establish local diagnostic reference levels of entrance surface air kerma for every institution for six most frequent X-ray examinations. Also, local diagnostic reference levels for the whole west region of Croatia were established and compared with the national diagnostic reference levels and latest published data. Median entrance surface air kerma values for thorax PA, thorax LAT, cervical spine AP, thoracic spine AP, lumbar spine AP, pelvis AP and sinuses are 0.14 mGy, 0.50 mGy, 0.52 mGy, 1.50 mGy, 2.52 mGy, 2.03 mGy, and 1.03 mGy, respectively. Diagnostic reference levels proposed for our region were comparable with other studies.

Abstract The present study aimed to propose local diagnostic reference levels (DRLs) formulated by calculating entrance surface doses for general radiography at 20 facilities of Aichi prefecture in Japan, by comparing these values with DRLs established in Japan in 2015 (DRLs 2015) and assessing radiation dose differences among facilities. X-ray outputs (half-value layer and air kerma) of each facility were measured with a non-invasive type of detector. The results were employed to formulate local DRLs based on the 75th percentiles of dose distributions. These local DRLs were lower than the DRLs 2015 for all examinations. If proposed local DRLs from other 46 prefectures can be collected, this paper can be used to benefit the next effort to draft better DRL for Japan.
