Magnetic resonance imaging of diffusion and perfusion

Topics in Magnetic Resonance Imaging, 1991
Two promising advances in MRI have recently evolved. Water proton directional "diffusion" as well as "perfusion" processes can be imaged in a rapid (on the order of milliseconds) and accurate manner. MR diffusion imaging is shown to effectively allow determination of the presence of anisotropic water diffusion in animal and human cerebral and spinal ...

Diffusion Tensor Magnetic Resonance Imaging of Brain Tumors

Magnetic Resonance Imaging Clinics of North America, 2005
DTI seems to offer the possibility of adding important information to presurgical planning. Although experience is limited, DTI seems to provide useful local information about the structures near the tumor, and this seems to be useful in planning. In the future, DTI may provide an improved way to monitor intraoperative surgical procedures as well as ...

[Diffusion spectrum magnetic resonance imaging].

Beijing da xue xue bao. Yi xue ban = Journal of Peking University. Health sciences, 2011
Diffusion spectrum imaging (DSI), a newly developed MRI technique, affords the capacity to map complex fiber architectures in tissues with sufficient angular resolution by imaging the spectra of tissue water diffusion. By contrast, diffusion tensor imaging (DTI), the currently widely used technique based on the 2nd order tensor model, obtains an ...

Perfusion/Diffusion Quantitation with Magnetic Resonance Imaging

Investigative Radiology, 1992
Quantitation of perfusion and diffusion in tissues using magnetic resonance imaging (MRI) techniques is an active area of research in many laboratories. Several different approaches have been taken to address the problem of determining microcirculatory flow or perfusion in the body with MRI.

Magnetic Resonance Imaging of Diffuse Liver Diseases

Topics in Magnetic Resonance Imaging, 2002
The intrinsic soft tissue contrast and exquisite sensitivity to contrast agents are unique attributes of magnetic resonance imaging that are beneficial when evaluating diffuse liver disease. Much like a pathologist uses different tissue or cell marker stains, the magnetic resonance imager can use a variety of imaging strategies to elucidate pathologic ...

Diffusion tensor magnetic resonance imaging

2018
Abstract The microstructure of the heart has a major impact on its mechanical and electrical properties. Diffusion tensor magnetic resonance imaging (DTI) exploits the anisotropic restriction of water diffusion in the myocardium to resolve its microstructure.

Diffusion Magnetic Resonance Imaging in Infantile Neuroaxonal Dystrophy

Journal of Computer Assisted Tomography, 2003
A 7-month-old girl with infantile neuroaxonal dystrophy is reported. In diffusion MRI, the pyramidal tracts and dentate nuclei had high signal on b = 1,000 s/mm2 images and low apparent diffusion coefficient (ADC) values. This pattern likely reflected the presence of abnormal (dystrophic) axons with restricted mobility of water molecules.

Diffusion Magnetic Resonance Imaging of Solid Vestibular Schwannomas

Journal of Computer Assisted Tomography, 2003
Six patients with solid vestibular schwannomas were studied by diffusion magnetic resonance imaging to assess if this modality adds new information for these tumors, because there is no previous report in the relevant literature. The sizes of the tumors ranged from 2.2 to 4.7 cm with respect to their largest diameters.
