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...

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...

BACKGROUND Despite the increasing use of positron emission tomography/computed tomography (PET/CT) in the management of patients with breast cancer, its role is yet to be defined. PATIENTS AND METHODS We reviewed PET/CT scans carried out in breast cancer patients, the indication, concordance/discordance with other imaging and whether their use had altered patient management. RESULTS PET/CT ...

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...

INTRODUCTION The aims of this study was to show the accuracy and clinical usefulness of endoscopic ultrasonography (EUS) with EUS-guided fine needle aspiration (FNA) in the diagnosis and staging of pancreatic cancer not obvious in computed tomographic (CT) scan abdomen imaging. MATERIALS AND METHODS Five male patients were evaluated; 4 presented with obstructive jaundice and 1 had unexplained...

AIM To evaluate the diagnostic yield of a selective brain (18)F-FDG PET/CT in neurologically asymptomatic patients with small cell lung cancer. MATERIAL AND METHODS Twenty-one neurologically asymptomatic patients referred to our service between July 2008 and December 2009 for staging of small cell lung cancer were included in the study. All underwent a standard (18)F-FDG PET/CT study followed...

BACKGROUND The fusion of fluoro-2-deoxy-D-glucose-positron emission tomography (FDG-PET) with CT scans has been shown to improve diagnostic accuracy and staging in non-small cell lung cancer. We report on the influence of PET-CT fusion on the management of patients with head and neck cancer. METHODS Thirty-six patients with intact primary head and neck cancers treated with radiation therapy (...

UNLABELLED Study Type--Diagnostic (exploratory cohort) Level of Evidence 2a. What's known on the subject? and What does the study add? Staging of patients with prostate cancer is the cornerstone of treatment. However, after curative intended therapy a high portion of patients relapse with local and/or distant recurrence. Therefore, one may question whether surgical lymph node dissection (LND) i...

Introduction: Accurate evaluation of femoral and tibial torsion is essential for children or adult with legs deformity, becuse incorrect legs morphogenesis can lead to pathological situation. CT scan is commonly used for the measurement of skeletal bone parameters. But, disability in imaging from standing and sitting posture and absorb dose of patients are deficits of this meth...
