Schwächungskorrektur bei der Myokard-SPECT

  • Chapter
Single-Photon-Emissions-Computertomographie (SPECT) des Herzens

  • 42 Accesses

Zusammenfassung

Die Schwächung der Emissionsquanten führt besonders bei SPECT-Aufnahmen des Herzens zu Artefakten und fehlerhafter Repräsentation von Aktivitätsverteilungen im Schnittbild. Darch wird die Spezifität klinischer Myokardperfusionsstudien reduziert. Verfahren zur Korrektur der Schwächung bei SPECT besonders in Situationen einer nichthomogenen Schwächungsverteilung sind deshalb wichtig. Allerdings ist hier eine Schwächungskorrektur nicht einfach durchzuführen. Es existieren unterschiedliche Lösungsansätze, die zum einen vor der Rekonstruktion der Schnittbilder, zum anderen nach der Rekonstruktion angewendet werden. Die Fortschritte in der Computertechnologie machen neuerdings die Anwendung dieser Verfahren auch in der klinischen Routine möglich
