Functional Susceptibility Weighted Magnetic Resonance Imaging
In this chapter we describe the basics of BOLD based fMRI starting from the point already described in previous chapters (the paramagnetism of deoxyhaemolobin and its consequences for the MR signal). This will include the current view on the influence of physiological parameters (CBF, CBV and CMRO2) on the BOLD signal, the link to neuronal activation and its temporal profile. Furthermore, this ...
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 کاملPreexisting cerebral microbleeds on susceptibility-weighted magnetic resonance imaging and post-thrombolysis bleeding risk in 392 patients.
BACKGROUND AND PURPOSE The question whether cerebral microbleeds (CMBs) visible on MRI in acute stroke increase the risk for intracerebral hemorrhages (ICHs) or worse outcome after thrombolysis is unresolved. The aim of this study was to analyze the impact of CMB detected with pretreatment susceptibility-weighted MRI on ICH occurrence and outcome. METHODS From 2010 to 2013 we treated 724 pati...
متن کاملSusceptibility-Weighted Magnetic Resonance Imaging in the Evaluation of Dementia
An 88-year-old woman with a clinical diagnosis of Alzheimer's disease and advanced dementia, was evaluated with standard MRI of the brain as well as Susceptibility Weighted Imaging (SWI) with the MRI. SWI revealed more extensive brain microhemorrhages than standard MRI techniques, allowing the radiologic diagnosis of cerebral amyloid angiopathy. SWI shows promise as a more sensitive diagnostic ...
