background and objective: chest x-ray is usually the first radiography performed for a newborn. this test is easily accessible and yet a basic screening method. different results have been reported in various studies regarding the diagnostic value of chest x-ray in cardiovascular disease in children. materials and methods: the study was carried out retrospectively using the medical files of 100...

results the data showed that vital signs and physical examination findings are useful screening parameters for predicting chest radiograph findings in outpatient settings. therefore, by implementing a prediction rule, we would be able to determine which patients would benefit from a chest x-ray (sensitivity, 94% and specificity, 57%). conclusion this study's findings suggest that requesting che...

a 50-year-old male underwent a check-up for an insurance company. chest x-ray revealed a large ball-like lesion in the posterior mediastinum. the finding was confirmed by computed tomography (ct) scan (figure 1). the patient was referred to our center, where he had a successful mass removal surgery (figure 2). pathology identified the mass as neurinoma.

background: proper placement of central venous catheter (cvc) tip could reduce early and late catheter-related complications.although the live fluoroscopy is standard of care for placement of the catheter, it is not available in many centers. therefore, the present study evaluated the sensitivity and specificity of bedside chest x-ray (cxr) for proper positioning of the catheter tip. materials ...

conclusion the cv value correlated more closely with low lvef and more accurately indicated an enlarged heart than ca or ctr. this may be due to the fact that an anteroposterior measurement of heart size is included in the former but not the latter two measurements. these study results may help quantify left heart enlargement with greater accuracy than may be obtained from standard cxr. backgro...

conclusions in patients with tm, bone widening, trabeculation, paraspinal masses and facial bone deformity were lower than patients with ti, whichcan be related to effectiveness of therapy with blood transfusion irrespective of its adverse effects in tm patients. results all radiologic findings were significantly higher in patients with ti compared to tm (p< 0.05). in patients with ti, only tra...

background: chest radiography is one of the most usual diagnostic tools for respiratory distress. objective: the purpose of this study is to assess the specificity, sensitivity and clinical value of chest radiography of neonates with respiratory distress.patients and methods: a descriptive- analytical study was conducted on 102 neonates that were in neonatal intensive care unit of imam reza and...

background: chest x-ray has an important role in the diagnosis of tuberculosis (tb). the aim of this study was to determine the radiological changes in patients with smear positive pulmonary tuberculosis.methods: in this study, 325 patients with smear positive pulmonary tb was enrolled. the affected lobe or lobes of the left or right lung were recorded. the types of involvement were categorized...

background: the radiation doses resulting from diagnostic x-ray examinations are routinely measured in terms of entrance surface dose (esd) and effective dose (ed). in this study, for the purpose of radiation protection, the radiation doses received from digital chest x-ray examination were evaluated in terms of esd and ed. material and methods: the ed was calculated by using the mcnp monte car...

right atrial dilation due to left heart disease is a common complication among adults. the present review aimed to describe a case of massively dilated right atrium in a female patient presenting with valvular heart disease and no atrial fibrillation. the results of chest x-ray revealed a large opacity filling the lower right hemithorax, falsely interpreted as a mediastinal mass. during the tra...
