Application of LAVA multi-phase dynamic enhanced technique combined with DWI in evaluating prostate lesions

Abstract

Objective To explore the value of liver acquisition with volume acceleration(LAVA) multi-phase dynamic enhanced technique combined with magnetic resonance diffusion weighted imaging(DWI) in evaluating prostate lesions.Methods Totally 67 prostate disease patients confirmed by histopathology and follow-up were included in the present study.The patients included 19 with prostate cancer(PCa) and 48 with benign prostate hyperplasia(BPH).LAVA multi-temporal enhancement and DWI scanning were performed,and the values of apparent diffusion coefficient(ADC) were calculated.Two experienced radiologists evaluated the results in a double-blinded manner;the qualitative diagnosis accuracy rates of the T-SI curves alone or in combination with ADC for PCa and BPH were compared.Results The accuracy rates of T-SI curve alone for qualitative diagnosis of PCa,BPH were 57.9% and 72.8%,and those of T-SI curve combined with ADC value were 73.7% and 87.5%,respectively.Conclusion LAVA multi-phase dynamic enhanced technique combined with ADC is of great value for differential diagnosis of benign and malignant prostate lesions.
