Diffusion-Weighted MR Imaging in Brain Tumor
Primary neoplasms of the central nervous system (CNS) have a prevalence of between 15,000 and 17,000 new cases annually in the United States and are estimated to cause the deaths of 13,000 patients. Gliomas are the leading cause of primary CNS tumors, accounting for 40–50% of cases and 2–3% of all cancers4. Despite new treatment techniques, patients’ survival still remains very low, varying bet...
متن کاملDiffusion-weighted MR imaging in gynecologic cancers
Diffusion-weighted imaging (DWI) reflects changes in proton mobility caused by pathological alterations of tissue cellularity, cellular membrane integrity, extracellular space perfusion, and fluid viscosity. Functional imaging is becoming increasingly important in the evaluation of cancer patients because of the limitations of morphologic imaging. DWI is being applied to the detection and chara...
متن کاملDiffusion-weighted MR imaging of the brain.
Diffusion-weighted magnetic resonance (MR) imaging provides image contrast that is different from that provided by conventional MR techniques. It is particularly sensitive for detection of acute ischemic stroke and differentiation of acute stroke from other processes that manifest with sudden neurologic deficits. Diffusion-weighted MR imaging also provides adjunctive information for other cereb...
متن کاملDiffusion-Weighted MR Imaging of Intracerebral Hemorrhage
OBJECTIVE To document the signal characteristics of intracerebral hemorrhage (ICH) at evolving stages on diffusion-weighted images (DWI) by comparison with conventional MR images. MATERIALS AND METHODS In our retrospective study, 38 patients with ICH underwent a set of imaging sequences that included DWI, T1-and T2-weighted imaging, and fluid-attenuated inversion recovery (FLAIR). In 33 and 1...
متن کاملDiffusion-Weighted MR Imaging and Ischemic Stroke
Magnetic resonance imaging (MR) of ischemic cerebrovascular events with standard T1and T2-weighted spin-echo techniques is widely employed. Standard MR demonstrates vascular changes such as the absence of a flow void and the presence of arterial enhancement within 2-4 hours of ischemic stroke onset in some cases ( 1 ). The earliest morphologic change in the brain parenchyma, swelling, is visibl...
