Zusammenfassung
Klinisches/methodisches Problem
Knöcherne Infekte stellen nicht selten eine diagnostische und klinische Herausforderung dar.
Radiologische Standardverfahren
Nuklearmedizinische Standardverfahren für die Diagnostik akuter und chronischer Knocheninfekte sind die Mehrphasenskelettszintigraphie und die Infektszintigraphie mit markierten Leukozyten.
Methodische Innovationen
Die Einführung von Hybridtechnologien wie der SPECT/CT hat die nuklearmedizinische Infektbildgebung tiefgreifend verändert.
Leistungsfähigkeit
Die SPECT/CT erlaubt bei der Frage nach Knocheninfekten insgesamt eine wesentlich genauere Beurteilung als planare Aufnahmen und SPECT.
Bewertung
Die integrierte Akquisition von metabolischer, funktioneller und topographisch-morphologischer Information mit SPECT/CT steigerte insbesondere die Spezifität der Mehrphasenskelettszintigraphie und der Infektszintigraphie mit markierten Leukozyten.
Abstract
Clinical/methodical issue
Skeletal infections are often a diagnostic and clinical challenge.
Standard radiological methods
Nuclear imaging modalities used in the diagnostic workup of acute and chronic skeletal infections include three-phase bone scintigraphy and scintigraphy with labelled leucocytes.
Methodical innovations
The introduction of hybrid technologies, such as single photon emission computed tomography/computed tomography (SPECT/CT) has dramatically changed nuclear medical imaging of infections.
Performance
In general SPECT/CT leads to a considerably more accurate diagnosis than planar or SPECT imaging.
Achievements
Given the integrated acquisition of metabolic, functional and morphological information, SPECT/CT has increased in particular the specificity of three-phase skeletal scanning and scintigraphy with labeled leucocytes.
