rhabdomyosarcoma is a common primary childhood malignancy that rarely metastasizes to the breast. we report a patient with a primary sinonasal rhabdomyosarcoma metastasizing to the breast, with no distant spread. we describe the imaging appearance of rhabdomyosarcoma on magnetic resonance imaging (mri), particularly on diffusion-weighted imaging (dwi) and apparent diffusion coefficient (adc) se...

background: cancer is the third cause of death in iran and its incidence is rising alarmingly. however, a study reported that kohgilooyeh and boyerahmad (a small province in iran) seems to have substantially lower incidence rate of cancer compared to the other parts of the country. this study is conducted to investigate the epidemiological features of cancer regarding three key factors (sex, ag...

background: the induction of cancer appears to be the most important effect of low-dose ionizing radiation to occur in an exposed population. in developing countries 94% of human radiation is from natural sources. in iran some high altitude regions such as, chaharmahal & bakhtiari has high levels of the natural background radiation (higher than the worldwide average). therefore, investigation o...

the purpose of this study was to investigate the incidence of different types of skin diseases among 657 children who were seen during one year period (oct. 1971-setp. 1972) at the skin clinics of the isfahan university hospital. the incidence of different types of skin disease was compared with those of the adults. in general this study shows that in isfahan area the incidence of skin infectio...

objective neonates, for many reasons, are at particular risk for the development of seizures, which are a strong predictor of later morbidity and mortality in infants. we undertook this study to determine the incidence, etiologic distribution and neonatal seizure type in neonates with hospital admission over a period of 4 years. materials and methods this, a retrospective study of newborns admi...

Different causative factors acting on the pancreas can result in diseases such as pancreatitis, diabetes and pancreatic tumors. The high incidence and mortality of pancreatic diseases have placed diagnostic imaging in a crucial position in daily clinical practice. In this mini-review article different pancreatic imaging techniques are discussed, from the standard clinical imaging modalities and...

Despite the significant impact of postoperative delirium on surgical outcomes and the long-term prognosis of older patients, its neural basis has not yet been clarified. In this study we investigated the impact of premorbid brain microstructural integrity, as measured by diffusion tensor imaging before surgery, on postoperative delirium incidence and severity, as well as the relationship among ...

OBJECTIVE The goal of this study was to develop a model that integrates imaging and clinical information observed at lesion incidence for predicting the recovery of white matter lesions in multiple sclerosis (MS) patients. METHODS Demographic, clinical, and magnetic resonance imaging (MRI) data were obtained from 60 subjects with MS as part of a natural history study at the National Institute...

BACKGROUND There are several situations in which magnetic resonance imaging (MRI) might impact whether an cerebrovascular event is considered a new stroke. These include clinically non-focal events with positive imaging for acute cerebral infarction, and worsening of older symptoms without evidence of new infarction on MRI. We sought to investigate the impact of MRI on stroke detection and stro...
