Brain microhemorrhages detected on T2*-weighted gradient-echo MR images.
BACKGROUND AND PURPOSE Multifocal microhemorrhages have been reported to be commonly found in the brain of patients with systemic hypertension and spontaneous brain hemorrhage. The factors associated with these lesions detected on T2*-weighted gradient-echo images were examined to determine whether these lesions serve to indicate different types of microangiopathy and to predict a patient's ris...
متن کاملIntratumoral microhemorrhages on T2*-weighted gradient-echo imaging helps differentiate vestibular schwannoma from meningioma.
BACKGROUND AND PURPOSE Vestibular schwannomas (VS) may be difficult to differentiate from cerebellopontine angle (CPA) meningiomas. Demonstration of microhemorrhages in VS on T2*-weighted gradient-echo (GRE) sequences may have potential value to differentiate VS from CPA meningiomas. MATERIALS AND METHODS In this prospective study of 20 patients, MR imaging was performed with T2*-weighted GRE...
متن کاملSWI-based method for emphasizing susceptivity changes on liver T2* multi-echo gradient-echo MRI
Introduction It is well known that the susceptibility difference between tissues, such as venous blood and surrounding tissue, causes a different bulk magnetization that can be observed both in magnitude and phase images: as a signal amplitude loss due to a reduced T2*, and as a local frequency variation of the protons inside the vessel that results in a phase angle Φ of the venous blood signal...
متن کاملFiber orientation-dependent white matter contrast in gradient echo MRI.
Recent studies have shown that there is a direct link between the orientation of the nerve fibers in white matter (WM) and the contrast observed in magnitude and phase images acquired using gradient echo MRI. Understanding the origin of this link is of great interest because it could offer access to a new diagnostic tool for investigating tissue microstructure. Since it has been suggested that ...
متن کاملPseudo-subarachnoid hemorrhage demonstrated by T2*-weighted gradient echo MRI.
was referred to the neurology department for comatose state with brainstem dysfunction. Non-contrast brain CT showed diffuse cerebral edema with subarachnoid hemorrhage (SAH)-like appearance (Fig. 1A). A lumbar puncture was not carried out because of the brain edema which was revealed in CT examination. T2*-weighted gradient-echo MRi revealed enlarged subarachnoid vessels that were not consiste...
