ABSTRACT
Objective Toinvestigatethevalueof3.0T MRreducedfield-of-view (rFOV)IVIM-DWIondistinguishingprostate cancerandprostatehypertrophy.Methods 30patientswithpathologicallyprovenprostatecancerand38patientswithprostatehypertrophy accordingtotheresultsofbiopsywereanalyzedretrospectively,whounderwent3.0T MRrFOV multipleb-valueDWIscanpreoperatively.The DWIscanwasperformedusing11b-valuesof0,30,50,100,150,200,400,800,1000,1500and2000s/mm2.ADC,slowdiffusion coefficient(D),fastdiffusioncoefficient(D?)andperfusionfraction(f)weremeasuredoncancerousfociandprostatehyperplasiafoci.Allofthe datawereanalyzed.Results TheADC,D,D?andfvaluesoftheprostatecancerwere(0.61±0.12)×10-3 mm2/s,(0.41±0.08)×10-3 mm2/s, (88.0±40.3)×10-3mm2/s,289.3%±29.4%,respectively,and(09.0±01.7)×10-3mm2/s,(05.4±01.3)×10-3mm2/s,(46.1±15.3)×10-3 mm2/s, 474.3%±10.85%,respectively,forprostatehypertrophy.Thedifferencesamongthefourparameterswerestatisticallysignificant(P<0.05).The areasofADC,D,D?andfvaluesunderROCcurvestodistinguishbetweenprostatecancerandprostatehypertrophywere09.32,08.27,01.58,0.976, respectively.Conclusion 3.0T MRrFOVIVIM-DWIcanreflectthetruewaterdiffusion motionandperfusionintheprostate,and maycontributetothedifferentialdiagnosisofprostatecancerandbenignprostatehyperplasia.
