conclusion the dwmri is a useful technique for evaluating activity of fistulas with abscess. perianal fistula visibility is greater with combined t2wi and dwmri than t2wi alone. patients and methods fifty-three patients with 56 perianal fistulas were included in the current retrospective study. the t2-weighted imaging (t2wi) and dwmri were performed and apparent diffusion coefficient (adc) valu...

background endometrial carcinoma is a highly prevalent gynecologic malignancy. the international federation of gynecology and obstetrics (figo) staging system underwent significant revision on 2009. key changes in the figo staging system include simplification of stage i endometrial cancer and removal of cervical mucosal invasion as a separate stage. mri is a noninvasive diagnostic method for p...

background: multiple sclerosis (ms) is an autoimmune inflammatory disease  that affects  the  central  nervous system. except tremor, other movement disorders such as parkinsonism are less frequent  in ms. however, some investigations  have shown inflammatory and autoimmune aspects of parkinson’s disease. in this study, we report eight new cases of ms who present parkinson’s disease. methods:  ...

background: a solitary necrotic nodule (snn) of the liver is an uncommon lesion, which is different from primary and metastatic liver cancers. objectives: to analyze the classification, ct and mr manifestation, and the pathological basis of solitary necrotic nodule of the liver (snn) in order to evaluate ct and mri as a diagnosing tool. patients and methods: this study included 29 patients with...

background: the monoclonal antibody, c595, against breast cancer cell line was conjugated with cyclic anhydride gadolinium-diethylenetriaminepenta-acetic acid (gd-cdtpaa) to produce gd-dtpa-c595 and used as specific breast cancer cell line (mcf-7) contrast agents in magnetic resonance imaging (mri).  methods: after incubation of breast cancer cell line (mcf-7), with different contrast agents (g...

the purpose of this study was to investigate the brain activation patterns in response to thehuman color preference by using a functional magnetic resonance imaging (fmri). a total of 31 healthyhumans without color blindness were participated in this study. the brain activation was induced by viewingof eight different colors: black, gray, blue, green, earthy yellow, red, yellow and white. the q...

background: finding a suitable method for rapid, accurate and reliable estimation of absorbed dose has high priority in management of the radiation exposed persons. shortly after radiation exposure, apoptosis is a major detriment in proliferative tissues such as the hematopoietic system. therefore, quantification of apoptosis in these tissues could be useful for rapid estimation of radiation ex...

aim and background: it has since long been known that there is strong relation between   psychological status and functional gastrointestinal disorders (fgid). however, until recently, the nature of this putative relationship was unclear due to a lack of non-invasive methods to investigate the neurobiological mechanisms underlying this relationship.  functional brain imaging has provided a meth...
