Zusammenfassung
Hintergrund
Quantitative Verfahren gewinnen in der pädiatrischen Radiologie zunehmend an Bedeutung. Mithilfe der Quantifizierung können objektivierbare Messwerte generiert werden, die über die rein morphologische Beschreibung pathologischer Veränderungen hinausgehen.
Ziel der Arbeit
Ziel der vorliegenden Übersichtsarbeit ist die zusammenfassende Darstellung wichtiger quantitativer Techniken im Bereich Ultraschall, Computer- (CT) und Magnetresonanztomographie (MRT).
Material und Methoden
Anhand von Literatur und eigenen Fallbeispielen werden verschiedene quantitative radiologische Verfahren erläutert.
Ergebnisse
Volumetrie, Ultraschallelastographie, CT-Dichtemessung sowie „dual-source, dual-energy CT“ stellen relevante quantitative Methoden in der pädiatrischen Radiologie dar. Im Bereich der MRT steht eine Vielzahl quantitativer Techniken zur Verfügung (u. a. Messung der Fettfraktion, kardiales „mapping“, Diffusionsbildgebung), die überaus vielfältig eingesetzt werden. Mit neuen Technologien wie der Hybrid- oder molekularen bildgebenden Untersuchung kann das Spektrum quantitativer Methoden zukünftig noch erweitert werden.
Schlussfolgerung
Quantitative bildgebende Untersuchungstechniken werden im Zuge der verstärkten Individualisierung in der Medizin weiter an Bedeutung gewinnen. Die immer spezifischeren Therapien erfordern in Zukunft dedizierte quantitative bildgebende Untersuchungen.
Abstract
Background
Quantitative methods are becoming more important in pediatric radiology. Objective measurement values can be generated by quantification, which extend beyond the purely morphological description of pathological alterations.
Objective
The objective of this review article is to summarize important quantitative techniques in the fields of ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI).
Material and methods
Various quantitative radiological techniques are reviewed based on the literature and clinical case examples.
Results
Volumetry, ultrasound elastography, measurements of CT attenuation, and dual-source, dual-energy CT represent relevant quantitative methods in pediatric radiology. In the field of MRI, many quantitative techniques are available or are being developed (e.g. fat fraction measurement, cardiac mapping, diffusion-weighted imaging), which can be used for a variety of diseases. New technologies, such as hybrid and molecular imaging examinations will further enlarge the spectrum of quantitative imaging in the future.
Conclusion
Quantitative imaging examination techniques will become more important in the context of an increasing individualization in medicine. The greater specificity of treatment will increasingly require quantitative and target-specific imaging in the future.
