MATERIALS AND METHODS Twenty-two patients that were sent to our department with preliminary diagnoses of HCs or abscess were included in the study. Thirty lesions were evaluated. MRI included T1-weighted fast gradient echo, T2-weighted half-Fourier acquisition single-shot turbo spin echo, and DW single-shot echo planar pulse sequencing (b, 0, 50, and 1000 s/mm(2)). The apparent diffusion coefficient (ADC) values (mm(2)/s) of the HCs, asscesses, and simple cysts were calculated. RESULTS No statistically significant difference was found between the ADC values of type 1 and 3 (P>0.05) HCs and of simple cysts and type 1 HCs (P>0.05). The ADC values of abscesses were significantly lower than those of type 1 and type 3 HCs, and simple cysts. No statistically significant difference was found between the ADC values of abscesses and type 4 HCs (P>0.05). Type 4 lesions exhibited significantly lower ADC values in comparison to type 1 and 3 HCs. CONCLUSION DW-MRI helps differentiate type 4 lesions from other cysts and can distinguish abscesses from hydatid cysts other than type 4 as well as from simple cysts. Type 1 HCs cannot be differentiated from simple cysts using ADC values alone, and type 4 lesions are indistinguishable from abscesses.eninfo:eu-repo/semantics/openAccessLiverEchinocaccosisMagnetic resonance imagingDiffusion-weighted MRIHepatic-lesionsDiseaseDiagnosisImagesBodyRadiology, nuclear medicine & medical imagingAdultAgedCystsDiagnosis differentialDiffusion magnetic resonance imagingEchinococcosis, hepaticFemaleHumansLiverLiver abscessLiver diseasesMaleMiddle agedProspective studiesYoung adultArticle0002850385000062-s2.0-7865010011527928716420658444Radiology, nuclear medicine & medical imagingDiffusion Weighted Imaging; Kurtosis; Molecular DiffusionAdultAgedArticleCalculationClinical articleControlled studyDiagnostic accuracyDifferential diagnosisDiffusion coefficientDiffusion weighted imagingFemaleHumanImage reconstructionLiver abscessLiver cystLiver hydatid cystMaleStatistical significance
