Magnetic Resonance Imaging - Instrumentation
Research News and Information
Definition of 'Magnetic Resonance Imaging'Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques. Common names: Magnetic Resonance Imaging; Imaging, Magnetic Resonance; NMR Imaging; Imaging, NMR; Zeugmatography; Tomography, MR; Tomography, NMR; MR Tomography; NMR Tomography; Tomography, Proton Spin; Proton Spin Tomography; Magnetization Transfer Contrast Imaging; MRI Scans; MRI Scan; Scan, MRI; Scans, MRI |

Analysis of factors associated with volumetric data errors in gamma knife radiosurgery.
25 Nov 2009 
OBJECT: Gamma knife (GK) surgery is an important part of the treatment armamentarium for benign and malignant brain tumors. In general, quantitative volumetrical analysis of the tumor on neuroimaging studies is the most reliable method of assessment ... Read more...
New directions in clinical imaging of cortical dysplasias.
29 Sep 2009 Neuroimaging is essential in the work-up of patients with intractable epilepsy. In pediatric patients with medically refractory epilepsy, cortical dysplasias account for a large percentage of the epileptogenic substrate. Unfortunately, these are ... Read more...
Characterization of scaffolds for tissue engineering by benchtop-magnetic resonance imaging.
30 Aug 2009 Several publications have shown approaches for the optimization of tissue engineering constructs by magnetic resonance imaging (MRI). However, the technology is still scarcely used, probably because of the poor spatial resolution of clinical ... Read more...
