Magnetic Resonance Imaging - Methods
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 |

BACKGROUND: Magnetic resonance imaging (MRI) is an emerging tool to assess organ-specific iron load in patients with transfusion dependent anemia. OBJECTIVE: We performed MRI T2 star (T2*) assessment in 44 transfusion dependent patients to study the ... Read more...
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...
Effect of anti-IFN{beta} antibodies on MRI lesions of MS patients in the BECOME study.
Nov 2009 BACKGROUND: Interferon beta (IFNbeta) administered subcutaneously is immunogenic in some patients with multiple sclerosis (MS) and leads to the development of neutralizing antibodies (NAbs). Considerable evidence has accumulated that NAbs diminish ... Read more...
