Comparative analysis of radiation dose and low contrast detail detectability using routine paediatric chest radiography protocols

The Practice of Chest Radiography Using Different Digital Imaging Systems: Dose and Image Quality

Introduction: The study was undertaken to evaluate the practice of chest radiography using different digital imaging systems and its influence on dose and image quality.  Materials and Methods: The study was carried out in two hospitals from March 2016 to June 2016. Sixty ambulatory patients aged 21 to 60 years who were able to cooperate without difficulty and weighed between 60 to 80 kg were ...

Routine Admission and Preoperative Chest Radiography

Evaluation of radiation dose and image quality following changes to tube potential (kVp) in conventional paediatric chest radiography

PURPOSE A study of radiation dose and image quality following changes to the tube potential (kVp) in paediatric chest radiography. MATERIALS AND METHOD A total of 109 patients ranging from 1 month to 15 years were included in two phases of the study. Phase 1 investigated the range of entrance surface air kerma (ESAK) values received from patients exposed to the existing exposure factors. In t...

Effect of Low Tube Voltage on Image Quality, Radiation Dose, and Low-Contrast Detectability at Abdominal Multidetector CT: Phantom Study

PURPOSE To investigate the effect of low tube voltage (80 kV) on image quality, radiation dose, and low-contrast detectability (LCD) at abdominal computed tomography (CT). MATERIALS AND METHODS A phantom containing low-contrast objects was scanned with a CT scanner at 80 and 120 kV, with tube current-time product settings at 150-650 mAs. The differences between image noise, contrast-to-noise ...

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)...
