In order to determine the relevance of radiographs of the lumbar spine in an A&E department 225 consecutive patients presenting in a 6-month period with acute back pain were studied. An analysis of the number of radiographs performed and their association with particular factors in the history and examination of the patient was performed. A total of 108 patients had radiographs (48%), with a to...

Guidelines for lumbar spine radiography were agreed by consultation between staff in the radiology, accident and emergency and neurosurgical departments of a large teaching hospital. Study of 322 consecutive patients over an eight month period showed that the proportion of patients referred for radiography was reduced from 48.4% to 27.2% following introduction of the guidelines (p = 0.0002). Su...

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...

  Background: This study has aimed to measure the patient dose in entire spine radiography by EOS system in comparison with the digital radiography. Methods: EOS stereo-radiography was used for frontal and lateral view spine imaging in 41 patients in a prospective analytical study. A calibrated dose area product (DAP) meter was used for calibration of the DAP in EOS system. The accuracy and pr...

UNLABELLED BACKGROUND The mechanism behind parathyroid hormone (PTH) activation of bone remodeling is intimately dependent on the time of exposure of bone cells to hormone levels. Sustained high PTH levels trigger catabolism, while transitory elevations induce anabolism. The effects of hypoparathyroidism (PhPT) on bone are unknown. The objective was to study the impact of PhPT on bone minera...

OBJECTIVE To investigate the relationship between bone mineral density (BMD) and sagittal spinal balance in the Korean elderly population. METHODS The retrospective study included subjects aged 60 years and above, who had whole-spine lateral radiography and dual-energy X-ray absorptiometry (DEXA) within a year's gap between each other. Sagittal vertical axis (SVA) for evaluation of sagittal s...
