background & aim: dental implants should be surrounded with at least 1mm bone. assessing ridge width is an important part to achieve this goal. the use of ridge mapping to assess bone levels available avoids some of the problems associated with ct-scanning. the aim of this study was to assess the accuracy of ridge-mapping compared to ct-scan in determination of bony ridge widths. methods & mate...

introduction: pulmonary involvement secondary to systemic sclerosis (ssc) is the major cause of morbidity and mortality in ssc patients. we designed this study to determine the correlation of important lung function parameters with lung high resolution ct (hrct) scan findings.materials and methods: thirty–two consecutive diffuse ssc patients with pulmonary fibrosis were enrolled in this cross-s...

introduction: the selection of   optimal treatment of obstructive nephrouropathy requires information about the functional status of each kidney. nuclear renal scanning objectively measure differential renal function, multiple studies have demonstrated the role of assessment of renal perfusion and gfr with triphasic ct. the aim of this study is to assess the role of ct based on renal parenchyma...

metastasis of gastroesphageal junction (gej) adenocarcinoma in skeletal muscle is rare and primary sites for skeletal muscle metastases are usually lung, renal and colorectal cancer. we have encountered with the first case report of solitary psoas muscle metastasis of gej adenocarcinoma. here we describe a 65 years old man was diagnosed with gej adenocarcinoma in tertiary hospital, tehran, iran...

background: blunt abdominal trauma is one of the causes of mortality in emergency department. free fluid in the abdomen due to intra-abdominal blunt trauma can be determined by the surface probe of ultrasound. since the importance of this free fluid in hemodynamic stable patients with blunt trauma is associated with the unknown outcome for surgeons, this study was performed to evaluate the role...

abstract background: osteoid osteoma is a benign bony neoplasm and its classic treatment is surgery. in the r ecent decades percutaneous laser therapy was suggested to be replaced by surgery. in this study we have reviewed the results of the first applications of interstitial laser photocoagulation (ilp) for treatment of osteoid osteoma in iranian patients. materials and methods: in this case s...

Magnetic resonance imaging (MRI) uses a constant magnetic field and radio waves, a non-invasive method for examining tissues, organs and the skeletal system. Advantages and disadvantages of MRI are not fully understood; however, it has been commonly used in the diagnosis of skeleton and bone diseases (such as disk and spinal disorders, joint disorders (arthritis), bone tumours and tissues...

BACKGROUND Pelvic x-ray is a routine part of the primary survey of polytraumatized patients according to Advanced Trauma Life Support (ATLS) guidelines. However, pelvic CT is the gold standard imaging technique in the diagnosis of pelvic fractures. This study was conducted to confirm the safety of a modified ATLS algorithm omitting pelvic x-ray in hemodynamically stable polytraumatized patients...
