Tumour-to-brain ratios (TBRs) of 18F-FET uptake and 62 textural parameters were determined on summed images 20-40 min post-injection. Tracer uptake kinetics, i.e., time-to-peak (TTP) and patterns of time-activity curves (TAC) were evaluated on dynamic PET data from 0-50 min post-injection. Diagnostic accuracy of investigated parameters and combinations thereof to discriminate between brain metastasis recurrence and radiation injury was compared.ResultsDiagnostic accuracy increased from 81 % for TBRmean alone to 85 % when combined with the textural parameter Coarseness or Short-zone emphasis. The accuracy of TBRmax alone was 83 % and increased to 85 % after combination with the textural parameters Coarseness, Short-zone emphasis, or Correlation. Analysis of TACs resulted in an accuracy of 70 % for kinetic pattern alone and increased to 83 % when combined with TBRmax.ConclusionsTextural feature analysis in combination with TBRs may have the potential to increase diagnostic accuracy for discrimination between brain metastasis recurrence and radiation injury, without the need for dynamic 18F-FET PET scans. 000825824 536__ $$0G:(DE-HGF)POF3-573$$a573 - Neuroimaging (POF3-573)$$cPOF3-573$$fPOF III$$x0 000825824 588__ $$aDataset connected to CrossRef 000825824 7001_ $$0P:(DE-Juel1)131627$$aStoffels, Gabriele$$b1 000825824 7001_ $$0P:(DE-HGF)0$$aCeccon, Garry$$b2 000825824 7001_ $$0P:(DE-HGF)0$$aRapp, Marion$$b3 000825824 7001_ $$0P:(DE-Juel1)165921$$aSabel, Michael$$b4 000825824 7001_ $$0P:(DE-Juel1)141877$$aFilss, Christian$$b5 000825824 7001_ $$0P:(DE-HGF)0$$aKamp, Marcel A.$$b6 000825824 7001_ $$0P:(DE-Juel1)156479$$aStegmayr, Carina$$b7 000825824 7001_ $$0P:(DE-Juel1)166419$$aNeumaier, Bernd$$b8 000825824 7001_ $$0P:(DE-Juel1)131794$$aShah, Nadim J.$$b9 000825824 7001_ $$0P:(DE-Juel1)131777$$aLangen, Karl-Josef$$b10 000825824 7001_ $$0P:(DE-Juel1)143792$$aGalldiks, Norbert$$b11 000825824 773__ $$0PERI:(DE-600)1472718-3$$a10.1007/s00330-016-4638-2$$n7$$p2916–2927$$tEuropean radiology$$v27$$x1432-1084$$y2017 000825824 8564_ $$uhttps://juser.fz-juelich.de/record/825824/files/art%253A10.1007%252Fs00330-016-4638-2.pdf$$yRestricted 000825824 8564_ $$uhttps://juser.fz-juelich.de/record/825824/files/art%253A10.1007%252Fs00330-016-4638-2.gif?subformat=icon$$xicon$$yRestricted 000825824 8564_ $$uhttps://juser.fz-juelich.de/record/825824/files/art%253A10.1007%252Fs00330-016-4638-2.jpg?subformat=icon-1440$$xicon-1440$$yRestricted 000825824 8564_ $$uhttps://juser.fz-juelich.de/record/825824/files/art%253A10.1007%252Fs00330-016-4638-2.jpg?subformat=icon-180$$xicon-180$$yRestricted 000825824 8564_ $$uhttps://juser.fz-juelich.de/record/825824/files/art%253A10.1007%252Fs00330-016-4638-2.jpg?subformat=icon-640$$xicon-640$$yRestricted 000825824 8564_ $$uhttps://juser.fz-juelich.de/record/825824/files/art%253A10.1007%252Fs00330-016-4638-2.pdf?subformat=pdfa$$xpdfa$$yRestricted 000825824 909CO $$ooai:juser.fz-juelich.de:825824$$pVDB 000825824 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)145110$$aForschungszentrum Jülich$$b0$$kFZJ 000825824 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131627$$aForschungszentrum Jülich$$b1$$kFZJ 000825824 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)141877$$aForschungszentrum Jülich$$b5$$kFZJ 000825824 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)156479$$aForschungszentrum Jülich$$b7$$kFZJ 000825824 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)166419$$aForschungszentrum Jülich$$b8$$kFZJ 000825824 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131794$$aForschungszentrum Jülich$$b9$$kFZJ 000825824 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131777$$aForschungszentrum Jülich$$b10$$kFZJ 000825824 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)143792$$aForschungszentrum Jülich$$b11$$kFZJ 000825824 9131_ $$0G:(DE-HGF)POF3-573$$1G:(DE-HGF)POF3-570$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lDecoding the Human Brain$$vNeuroimaging$$x0 000825824 9141_ $$y2017 000825824 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000825824 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bEUR RADIOL : 2015 000825824 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000825824 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000825824 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000825824 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000825824 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000825824 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000825824 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000825824 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000825824 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000825824 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine 000825824 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000825824 9201_ $$0I:(DE-Juel1)INM-3-20090406$$kINM-3$$lKognitive Neurowissenschaften$$x0 000825824 9201_ $$0I:(DE-Juel1)INM-4-20090406$$kINM-4$$lPhysik der Medizinischen Bildgebung$$x1 000825824 9201_ $$0I:(DE-Juel1)INM-5-20090406$$kINM-5$$lNuklearchemie$$x2 000825824 9201_ $$0I:(DE-82)080010_20140620$$kJARA-BRAIN$$lJARA-BRAIN$$x3 000825824 980__ $$ajournal 000825824 980__ $$aVDB 000825824 980__ $$aI:(DE-Juel1)INM-3-20090406 000825824 980__ $$aI:(DE-Juel1)INM-4-20090406 000825824 980__ $$aI:(DE-Juel1)INM-5-20090406 000825824 980__ $$aI:(DE-82)080010_20140620 000825824 980__ $$aUNRESTRICTED
