“…The main reasons are the age-related changes in brain sizes, overall and individual structure sizes (Tien et al, 1992;Paus et al, 1999;Durston et al, 2001;Giedd, 2004;Gogtay et al, 2004), and water content (Sakuma et al, 1991;Nomura et al, 1994), which is the basic substrate of the MRI signal (Paus et al, 2001). Adjustment in scanning parameters for data acquisition (Saunders et al, 2007), and use of ageappropriate structural brains for group analyses (Muzik et al, 2000) become critical. Much work needs to be done in this area.…”

With the development of functional neuroimaging tools, the past two decades have witnessed an explosion of work examining functional brain maps, mostly in the adult brain. Against this backdrop of work in adults, developmental research begins to gather a substantial body of knowledge about brain maturation. The purpose of this review is to present some of these findings from the perspective of functional neuroimaging. First, a brief survey of available neuroimaging techniques (i.e., fMRI, MRS, MEG, PET, SPECT, and infrared techniques) is provided. Next, the key cognitive, emotional, and social changes taking place during adolescence are outlined. The third section gives examples of how these behavioral changes can be understood from a neuroscience perspective. The conclusion places this functional neuroimaging research in relation to clinical and molecular work, and shows how answers will ultimately come from the combined efforts of these disciplines.

Neuroimaging in a Three-Year-Old Girl — MRI without Anesthesia: Easier Than One Thinks

et al. 2010

Magnetic resonance imaging (MRI) is the imaging modality of choice in the diagnosis of structural brain abnormalities in children. Routine scans are usually not reliable in pediatric neuroimaging without sedation before the age of seven. Before this age sedation or general anesthesia with procedural risks and additional costs might be needed. We report on MRI in a 3.1-year-old patient referred after a first seizure performed with a combination of role model and self-experience. MRI with high imaging quality was performed without the need for anesthesia in our daily routine. The imaging procedure was performed without previous preparation needed and within target date.Our reported technique of a combination of role model and self-experience, avoiding anesthesia in a 3.1-year-old girl is suitable for children and it is applicable in the daily routine.

“…Für die Untersuchung des Felsenbeins werden CISS-, FIESTA-, bzw. DRIVE-3D-Sequenzen (CISS = "constructive interference steady state", FIESTA = "fast imaging employing steady-state acquisition", DRIVE = "driven equilibrium") oder T2w 3D-Gradienten-Echo-Sequenzen mit 0,6 -0,8 mmSchichtdicke und 512er Matrix empfohlen[1,23].…”

EinleitungIn der Kinderradiologie stehen meist der Ultraschall oder die Röntgenaufnahme am Anfang der bildgebenden Diagnostik. Mit dem Ultraschall lassen sich bereits viele Fragen insbesondere im Abdomen und am Hals beantworten. Wird eine weiterführende Schnittbilddiagnostik erforderlich, kommt die MRT bevorzugt zum Einsatz. Aufgrund der fehlenden Strahlenbelastung und der nach heutigem Kenntnisstand fehlenden gesundheitlichen Risiken ist die MRT nach dem Ultraschall zum wichtigsten Schnittbildverfahren bei Kindern und Jugendlichen geworden. Mit den neueren Techniken wird eine immer schnellere Bildgebung ermöglicht, mit deren Hilfe neue Indikationen für die MRT erarbeitet worden sind. Sie wird heute in der Kinderradiologie in nahezu allen Körperregionen bei vielfältigen Fragestellungen eingesetzt. Für eine erfolgreiche Untersuchung mit aussagekräftigen Ergebnissen werden allerdings besondere Anforderungen an eine MRT-Untersuchung in dieser Altersgruppe gestellt: n Im Vergleich zur CT sind die Untersuchungszeiten deutlich länger. Um Bewegungen während der Messung zu vermeiden, die zu Artefakten führen und damit u. U. nicht auswertbare Bilder verursachen, sind vor allem bei Kleinkindern geeignete Maßnah-men zur Ruhigstellung erforderlich. n Die zu untersuchenden Volumina sind im Vergleich zur Situation bei Erwachsenen oft sehr klein, sodass besondere Anforderungen an die Untersuchungstechnik gestellt werden müssen. Dabei ist besonderes Augenmerk auf eine geeignete Auswahl von Spulen und Sequenzen zu richten.
