Magnetic Resonance Imaging
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 |

Alexander disease: An important mimicker of focal brainstem glioma.
13 Dec 2009 
We report the case of a 6-year-old male who was referred to a tertiary oncology center with a focal brainstem lesion which was presumed to be neoplastic. Due to the symmetric nature of the lesion on magnetic resonance imaging, the evaluation was ... Read more...
Pilocytic astrocytoma in a child with Noonan syndrome.
29 Nov 2009 Noonan syndrome (NS; MIM 163950) is an autosomal dominant dysmorphic syndrome characterized by distinct facial features, cardiac anomalies, short stature, and motor delay. Activating mutations in PTPN11, encoding the protein tyrosine phosphatase ... Read more...
29 Nov 2009 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...
