background: early diagnosis of brain tumors has significant effect on the treatment process. brain metastatic tumors are usually diagnosed following the neurological symptoms in patients or incidentally after computerized tomography (ct) scan and magnetic resonance imaging (mri) requests of the brain. objectives: implementation of a new method for being informed about the origin of brain tumors...

calcifying aponeurotic fibroma (caf) is a rare, benign fibroblastic tumor that typically occurs in the palms of the hands and soles of the feet, in children and adolescents. due to its infiltrative nature, this tumor can mimic malignancy on preoperative magnetic resonance imaging (mri) and has a predilection for local recurrence. there are very few reports in the literature that describe featur...

case presentation we present a case with a typical picture of myocarditis but normal echocardiographic findings, the diagnosis of which was confirmed by cardiac mri. discussion in particular, cardiac mri data are useful in borderline cases or in the presence of discrepancy between clinical picture and echocardiographic results. introduction the diagnosis of myocarditis based on a spectrum of fi...

levamisole is an anthelmintic agent and also immunostimulant drug which is used to treat colorectal cancer. the present study aimed to show accidental consumption of levamisole alone induced multifocal inflammatory leukoencephalopathy. a 53-year-old male was admitted to the neurology department of farabi hospital (kermanshah, iran) with walking inability and recognition disorder. following clin...

background imaging plays a critical role not only in the detection, but also in the characterization of lung masses as benign or malignant. objectives to determine the diagnostic accuracy of dynamic magnetic resonance imaging (mri) in the differential diagnosis of benign and malignant lung masses. patients and methods ninety-four masses were included in this prospective study. five dynamic seri...

results stereoscopic displays of the nerves were obtained in all 24 elbows by vr, mip, and fiber tractography post-processing methods. the vr/mip post-processing methods were easier to perform compared to fiber tractography. there was no significant difference among the scores of fiber tracking and vr/mip reconstruction for single direction. the imaging quality scores of fiber tractography and ...

introduction: interhemispheric transmission of signal is done by corpus callosum (cc) as the largest fiber tract in brain. cc comprised 5 segments of rostrum, genu, body, isthmus, and splenium. contradictory reports exist about sexual dimorphism of cc. we designed this study to assess probable sexual differences of cc and its different parts in men and women. methods: we analyzed magnetic reson...

introduction: the magnetic resonance imaging (mri) technique permits to monitor the development of the embryo in vivo without causing any developmental defects. although increasing application of mri imaging are predicted in veterinary sciences, there is little information available about mri studies of avian embryos and their eggs. the objective of the present study was to evaluate the ostrich...

decidualized ovarian endometrioma is a rare phenomenon in pregnancy, which can mimic ovarian malignancy in imaging and often poses a diagnostic challenge. we report a case of a large ruptured decidualized ovarian endometrioma in a 15 weeks gestation patient, and we will describe the imaging characteristics (ultrasonography and mr imaging findings) and the histopathological findings (macro- and ...
