Abstract: Objective ToexplorethevalueofMRIindifferentiatingbetweenmass-formingchronicpancreatitis(MFCP)andpancreatic carcinoma(PC).Methods MRIdataof19caseswith MFCP,36caseswithPCand30normalcontrolcasesconfirmedbypathology orfollow-upwereanalyzedretrospectively.AllofthesubjectsunderwentroutineMRIandDWIscan.MRIcharacteristicsofdiseases andnormalpancreaswereanalyzed,andADCvalueswerecomparedamongthethreegroups.Results TheaverageADCvalueofthe MFCPgroupwas(1.41±0.25)×10-3 mm2/s,higherthanthatofthePCgroup (1.13±0.11)×10-3 mm2/s(P<0.05),andlower thanthatofthenormalcontrolgroup(1.50±0.27)×10-3 mm2/s(P<0.05).IntheT2WI,enhancedscanningarterialphase,andenhanced scanningportalphase,thesignalcharacteristicsofthelesionswerestatisticallydifferentbetweentheMFCPandPCgroup (P<0.05).The sensitivityandspecificityofthecombinationT2WI,enhancedarterialimagingandADCvaluewere86.9%and88.9%indifferentiatingMFCPand PC,whichwasbetterthananysinglemethod.Conclusion MRImulti-sequencecombinationisoneoftheeffectivemethodsforidentifyingPCand MFCP,andhasreferencevalueforclinicaldiagnosis.
