Abstract:
Objective ToevaluatethepredictivevalueofpreoperativeMRIsignalintensityindifferenttexturesofpituitaryadenoma (PA).Methods Accordingtotheinclusioncriteria,47casesofPA werecollected,including37softcasesand10firmcases.Different texturesofPAonMRIsignalintensityanddynamicenhancementcharacteristicswereanalyzed.Results T2WIintensitybetweentwo texturegroups(T2PA/T2WM、T2PA/T2GM、T2PA/T2CSFandSER)hadsignificantstatisticaldifferences(P<0.05).T1WIintensity betweentwotexturegroups(T1WIPA/T1WIPN )hadnosignificantstatisticaldifference(P>0.05).TheT2signalintensity(T2PA/T2WM、T2PA/T2GM、T2PA/T2CSF)andSERinsoftgroupwashigherthanthatinthefirmgroup.Predictivevalueofthetextureof PAbyusingtheROCcurveofT2PA/T2WM,T2PA/T2GM,T2PA/T2CSF,T1PA/T1PNandSER wereobtained,andtheareasunder theROCcurvewere0.857,0.835,0.856,0.630and0.781respectively.ThelargestareaundertheROCcurvewasT2PA/T2WM (P<0.05).Conclusion MRIT2signalintensityisrelatedtothetextureofPAandthoseindexescanbeusedtojudgethetextureofPA.
