STUDY DESIGN Single-cohort laboratory-based study. OBJECTIVES To measure thoracic spine extension motion during bilateral arm elevation using functional radiography and photographic image analysis. BACKGROUND Impairment of thoracic spine extension motion may impact shoulder girdle function. Motion of the thoracic spine during arm movement has not been directly measured using functional radi...

Pleuropulmonary blastoma (PPB) is a rare invasive primary malignancy in the thoracic cavity that occurs mainly infants and children. It often misdiagnosed not treated correctly promptly due to lack of specificity clinical symptoms conventional imaging presentations. We report 2.5-year-old boy who underwent X-ray chest radiography, CT, 18 F-FDG PET/CT. PET/CT images demonstrated sizeable cystic-...

Background:The most efficient application of ionizing radiation is serving medical purposes and using this radiation has caused people to learn that artificial sources of radiation exposure among these resources can be of highest exposure rate.  Objective: The present study is aimed at initially establishing a baseline for local-reference dose level in Mazandaran, Iran in 12 projections of the...

Many nuclear weapons complex workers were required to undergo medical x-ray examinations as a condition of their employment. To ensure that their dose reconstructions are complete, it is necessary to include the contributions from these examinations. X-ray procedures that must be evaluated include: (1) posterior-anterior and lateral radiography, and/or photofluorography, of the chest; (2) anter...

Introduction: Digital radiography has a major role in nowadays healthcare system so radiation protection (justification and optimization) is important in this field. Many related organizations to protection suggested to establish national and regional diagnostic reference level for medical procedures. Reference levels are typically set at the 75th percentile of the dose distri...

PURPOSE Rib fractures are the most common skeletal thoracic injuries resulting from blunt chest trauma. Half of the rib fractures are not detected upon a precise physical evaluation and radiographs. Recently ultrasonography (USG) has been investigated to detect rib fractures. But based on literature the usefulness of USG varies widely. This study was conducted to investigate the role of USG in ...

BACKGROUND Lumbar spine radiography has limited diagnostic value but low radiation dose compared with computed tomography (CT). The average effective radiation dose from lumbar spine radiography is about 1.1 mSv. Low-dose lumbar spine CT may be an alternative to increase the diagnostic value at low radiation dose, around 1 mSv. PURPOSE To determine the optimal settings for low-dose lumbar spi...

OBJECTIVE The aim of our study was to assess the potential of bedside lung ultrasound examination by the attending emergency physician in the diagnosis of acute pneumonia. MATERIAL AND METHODS This observational single-center study was conducted between January 2010 and June 2012 in the emergency unit of a general hospital, and analyzed 144 adult patients. The ultrasound examination was perfo...
