Comparison of T2 and T2*-weighted MR molecular imaging of a mouse model of glioma
BACKGROUND Standard MRI has been used for high-grade gliomas detection, albeit with limited success as it does not provide sufficient specificity and sensitivity to detect complex tumor structure. Therefore targeted contrast agents based on iron oxide, that shorten mostly T2 relaxation time, have been recently applied. However pulse sequences for molecular imaging in animal models of gliomas ha...

15 صفحه اولcomparison of mr images for age determination; t1 weighted images (t1wi) versus t2* weighted images (t2*wi)
purpose t1wi (t1 weighted image) was acquired in order to grade bone fusion following the studies by fifa (federation internationale de football associations). research using images other than t1wi has not been reported. the aim of this study is to evaluate the grade of epiphyseal fusion by t2* weighted images (t2*wi) and to investigate new findings on t2*wi as compared with t1wi. methods a tot...
متن کاملCardiac and Hepatic T2*-Weighted Magnetic Resonance Imaging
Abstract Background Iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. Severe iron deposition in tissues leads to organ dysfunction. Many organs can be affected such as heart, liver, and endocrine organs. Cardiac failure and liver fibrosis are the consequent of Iron overload in transfusion dependent hemoglobinopathy. Magne...
متن کاملDynamic contrast-enhanced T2*-weighted MR imaging of gliomatosis cerebri.
BACKGROUND AND PURPOSE MR imaging characteristics of gliomatosis cerebri reiterate the diffuse nature of this tumor but are nonspecific and thus may pose a diagnostic challenge. Because perfusion MR imaging can provide a physiologic map of the microcirculation, we compared the measured relative cerebral blood volume (rCBV) at perfusion imaging with histopathologic findings in gliomatosis cerebr...
