introduction: nowadays ionizing radiation has a considerable contribution in medical diagnostic and treatment. using ionizing radiation is increasing rapidly, so biological effects of ionizing radiation should be considered more. x-rays in the range of diagnostic radiology have hazardous effects and risks that are defined as random effects. these effects obey the lnt hypothesis that occur at lo...

OBJECTIVES Loss of motion following spine segment fusion results in increased strain in the adjacent motion segments. However, to date, studies on the biomechanics of the cervical spine have not assessed the role of coupled motions in the lumbar spine. Accordingly, we investigated the biomechanics of the cervical spine following cervical fusion and lumbar fusion during simulated whiplash using ...

Background: The primary objective of this study was to assess BMD change in Iranian females with breast cancer. Methods: A sample of 73 female breast cancer patients treated with adjuvant chemotherapy either alone or followed by radiotherapy between March 2013 and February 2016 were considered for this study. Bone mineral density (BMD) change was evaluated by measuring z-score of lumbar spin...

Approximately 79,000 spinal fractures occur annually in the United States. Roughly three out of every four fractures involve either the thoracic or the lumbar spine1,2. The most common site of injury in the thoracic and lumbar spine is the thoracolumbar junction, the mechanical transition zone between the relatively rigid thoracic spine and the more flexible lumbar region3-5. The thoracolumbar ...

Abstract Background The concept of diagnostic reference level (DRL) is considered a regular method to optimize radiation protection in imaging system. objective implementing for dose produce high-quality images by applying minimum based on the As Low Reasonably Achievable (ALARA) principle. Therefore, this study aimed evaluate status radiology wards educational hospitals affiliated with Birjand...

Mechanical stability of the lumbar spine is known to have implications for injury and chronic low back pain. Even though this topic is fairly covered by scientific literature, the role of abdominal muscles, in particular the deep once, is often neglected. Especially transverse abdominal (TA) muscle might play privileged role: with mainly transverse muscular fibers, both activated TA muscles com...

Transitional lumbosacral vertebrae in the form of SI lumbarization and LV sacralization are classified as spinal anomalies. In domestic medical literature, there few publications devoted to these pathological conditions. course a study available literature on problem transitional vertebrae, it was found that frequency cases diagnosis ranges from 4 30% clinical cases. The share patients with lum...
