normal 0 false false false en-us x-none ar-sa spinal hematoma is a rare and usually severe neurological disorder that, without adequate treatment, often leads to death or permanent neurological deficit. epidural as well as subdural and subarachnoid hematomas have been investigated in some studies. a 66-year-old man referred to our hospital because of acute onset paraplegia and incontinency star...

background chronic obstructive pulmonary disease (copd) is a devastating disease.while there is no cure for copd and the lung damage associated with this disease cannot be reversed, it is still very important to diagnose it as early as possible. objectives in this paper, we propose a novel method based on the measurement of air trapping in the lungs from ct images to detect copd and to evaluate...

introduction: using pan or selective computed tomography (ct) scan in management of multiple trauma patient is a matter of debate. therefore, the present study was designed aiming to compare the findings of pan and selective ct scans in management of multiple trauma patients. method: this is a prospective cross-sectional study, on patients presented to the emergency department (ed) of shohadaye...

Background: Computed Tomography (CT) is main contributor of population dose from diagnostic X-ray examinations. Children are more radiosensitive than adults, thus optimization of CT examination in these patients is essential. The purpose of this study was to evaluate dose delivered to pediatric patients’ undergoing CT examination of the common examinations and also establishing local Diag...

Introduction: Increasing in refer to computed tomography (CT-scan) imaging causes to increase in cumulative dose. Stereoradiography (EOS) is an X-ray imaging technology that, by eliminating scattering radiation, reduces patient's absorption dose and improves image quality.   Materials and Methods: This cross-sectional study was carried out in a hosp...

Patchy subcortical lesions are frequently identified on magnetic resonance imaging (MRI) of the brain in the elderly.On computed tomography (CT) these lesions appear as periventricular zones of lucency and have been termed "leuko-araiosis" by Hachinski and colleagues. Despite limited knowledge of the pathological correlates of the lesions, there has been speculation about their nature, pathophy...

A 3D industrial computed tomography (CT) manufactured based on a first generation CT systems, single-source – single-detector, was evaluated. Operation accuracy assessment of the manufactured system was achieved using simulation in comparison with experimental tests. Cs and Co were used as a gamma source. Simulations were achieved using MCNP4C code. Experimental tests of Cs were in good agreeme...

osteoma is a benign bone-forming tumor that usually arises in the craniofacial bones and rarely in the long bones. clavicular involvement is extremely rare. we report a 51-year-old woman with osteoma of the left clavicle. radiograph of the left shoulder showed a well-defined lobulated blastic mass in the proximal and mid-portion of the left clavicle. bone scintigraphy was performed 4 hours afte...

  Solitary pulmonary nodule (SPN) is a frequent finding on the chest x-ray and computed tomography. Nuclear medicine techniques play an important role in the diagnosis and management of SPN. In the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (PET) using 18-F-FDG, and 11-C-Methionine, and single photon em...
