Abstract:
MRI has been used in pediatric imaging for several years. It provides excellent anatomic detail and tissue characterization combined with the advantage that it is not associated with the application of ionizing radiation to the radiation sensitive infant organism. Low field MRI provides some additional advantages like a lower rate of sedations, easier monitoring of sedated patients and the option of interventional examination and therapy. The disadvantages, however, are the slightly prolonged examination times and the lower signal-to-noise ratio compared to high-field MR scanners. In the future, new techniques using modern gradient echo sequences will provide fast imaging methods with a very high signal-to-noise ratio which could partially replace conventional x-ray imaging. In the presented article we report our experiences in low-field MR imaging of pediatric patients. The possibilities as well as the limitations of this imaging modality are pointed out.
Insights
