The Value Of Mrcp Combined With Dwi In T-staging Of Gallbladder Cancer

ObjectiveTo investigate the value of conventional MRI,MR cholangiography and the Diffusion-Weighted MR Imaging in T-staging of gallbladder cancer(GBC).MethodsFifty-six patients with histologically proven GBCs were analyzed retrospectively.Staging was performed according to MR findings and compared with pathological findings.The accuracy of the two methods with or without DWI sequence was also compared.ResultsThe accuracy of staging of conventional MRI,MRCP was 87.5%(49/56).The sensitivity,specificity and accuracy of conventional MRI and MRCP in the stage of lesions as Tlvs>T2,≤T2vs≥T3,≤T3vsT4 lesions were 83.3%/98.0%/96.4%,92.3%/97.7%/96.4%,93.1%/88.8%/91.1%,respectively.The accuracy of staging of conventional MRI and MRCP combined with DWI was 91.1%(51/56).The sensitivity,specificity and accuracy of conventional MRI and MRCP Combined with DWI in the stage of lesions as T1vs>T2,<T2vs>T3,<T3vsT4 lesions were 83.3%/98.0%/96.4%,92.3%/97.707%/96.4%,93.8%/100%/96.4%,respectively.There was no statistical difference between the two groups(P>0.05).ConclusionConventional MRI and MRCP provides of excellent T-staging accuracy for GBC.The accuracy of T-staging can be improved by conventional MRI and MRCP combining with DWI,especially for T4 stage.
