Pediatric chest CT at chest radiograph doses: when is the ultralow-dose chest CT clinically appropriate?

Clinical Value of Low Dose CT- Scan in Pediatric Chest Diseases: Adequacy Assessment

Background Radiation dose about 400 times that of standard thoracic computed tomography (CT) in comparison with chest X- ray resulting in different approaches to decrease radiation dose have been established in the last few years to prevent possible side effects especially in children, such as low dose protocols. The aim of this study was assessment of clinical v...

Anteroposterior chest radiograph vs. chest CT scan in early detection of pneumothorax in trauma patients

Pneumothorax is a common complication following blunt chest wall trauma. In these patients, because of the restrictions regarding immobilization of the cervical spine, Anteroposterior (AP) chest radiograph is usually the most feasible initial study which is not as sensitive as the erect chest X-ray or CT chest for detection of a pneumothorax. We will present 3 case reports which serve for bette...

CT evaluation of patients with hemoptysis and normal chest radiograph

Background and objectives: to study the diagnostic accuracy of Computed Tomography in evaluation of various etiologies of hemoptysis with normal chest radiographs. Methods: Two hundred patients with hemoptysis and normal chest radiograph were evaluated with computed tomography from the period of December 2008 to October 2009. The patients were categorized according to the primary etiology and s...

Dose Reduction to the Thyroid Gland in Pediatric Chest Radiography

Background  It is remain a main concern that pediatric chest radiographies contribute to the significant radiation exposure to the thyroid gland as a more susceptible organ to radiation induced cancer. The aim of this study was to evaluate the entrance surface dose (ESD) of pediatric chest radiography compared to the diagnostic reference levels (DRL) and evaluation the efficacy of the lead (Pb)...
