background: bisphosphonates (bps) are used extensively for managing the osteoporosis. there are some controversies on atypical fractures of femur that associated with increase in cortical thickness (ct) and bps' use. in this study, the effects of alendronate consumption were studied on femoral ct as a predictor for atypical fracture.   methods: forty nine post-menopausal women aged 50-70 years ...

background: tins research was conduced to estimate the positive predictive value of physicians at kerman emergency services for traumatic patients who referred to radiology department of kerman hospital in 2001. methods: this study was a cross-sectional study and carried out on 353 patients. a questionnaire was used as a research instrument. results: three radiologists reported the films separa...

introduction quality control techniques used to test the components of the radiological system and verify that the equipment is operating satisfactorily. in this study, quality control (qc) assessment of conventional radiology devices was performed in frequently visited radiology centers of khuzestan province, iran. materials and methods fifteen conventional radiology devices were examined, bas...

conclusions because this incident may have occurred during the patient’s neonatal period, it may be a case of child abuse. in spite of the very limited number of cases in the literature, having a stepmother, a stepfather, or a babysitter, being the youngest child, or having family members who suffer from psychiatric disorders, (especially if these relatives are responsible for child care), livi...

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...

object: the gold standard for evaluating bone mineral density is dual energy x-ray absorptiometry (dexa).  prior studies have shown poor reliability using analog wrist x-rays in diagnosing osteoporosis. our goal was to investigate if there was improved diagnostic value to visual assessment of digital hand x-rays in osteoporosis screening. we hypothesized that similar to analog counterparts, dig...

gamma-rays emitted from the ground surface relate to the primary mineralogy and geochemistryof the bedrock, and the secondary weathered materials. this information can contribute significantly to anunderstanding of the geochemical and pedogenetic history of a region. the main aim of this paper was to study the relationship between ground gamma-ray data and basement geochemistry in the lese catc...

simulation of gamma and hadron showers in the energy range 100gev- 25tev has been carried out. for a big ideal cherenkov light array, characteristics of lateral distribution of cherenkov photon density have been studied. results from this ideal detector are compared with those simulated for a real tunka- like array to investigate experimental potential of using existence of a hump in lateral di...

eosinophilic granuloma is benign end of the spectrum of the langerhans cell histiocytosis (lch) which is characterized by solitary or multiple lesions in bones, skin, lung, lymph node etc. here, we present a case of a 13-year old boy with pain and swelling in the right parietal region of skull with no other complaint. a computerized tomography (ct) scan and subsequent fine needle aspiration cyt...
