Susceptibility-weighted imaging (SWI) is a high spatial resolution, three-dimensional (3D), gradientecho (GRE) magnetic resonance (MR) technique [1]. It uses both the T2*-weighted magnitude and the phase information to emphasize the magnetic susceptibility differences of various tissues or substances, such as blood products, iron, and calcification, by post-processing the magnitude images with ...

background: iron-mediated cardiomyopathy is the main complication of thalassemia major (tm) patients. therefore, there is an important clinical need in the early diagnosis and risk stratification of patients. the aim of this study was to evaluate the efficacy of tissue doppler imaging (tdi) to study cardiac iron overload in patients with tm using t2* magnetic resonance (mr) as the gold-standard...

Introduction: In recent years, there has been much interest in variant Creutzfeldt-Jakob disease (vCJD), shown to be caused by the same prion strain as that causing Bovine Spongiform Encephalopathy (BSE). With recent reports of blood transfusion associated transmission, the disease remains an important public health issue. For diagnosis, histopathologists often examine only the frontal cortex w...

detection of brain tissues using magnetic resonance imaging (mri) is an active and challenging research area in computational neuroscience. brain mri artifacts lead to an uncertainty in pixel values. therefore, brain mri segmentation is a complicated concern which is tackled by a novel data fusion approach. the proposed algorithm has two main steps. in the first step the brain mri is divided to...

background: to retrospectively describe imaging characteristics of liver metastases on fused fdg-pet/ mri data sets and to compare the diagnostic accuracy of mri and fused fdg-pet/mri data sets for the detection of liver metastases in patients undergoing systemic anticancer treatment. materials and methods: 43 oncological patients (mean age: 56+/- 11 years) were investigated by fdg-pet/ct and l...
