Differential value of MRI plain scan combined with enhanced scan in pathological subtypes of renal cell carcinoma
[Objective]To analyze the differential value of MRI plain scan combined with enhanced scan for pathological subtypes of renal cell carcinoma.[Methods]Clinical data of 114 renal cell carcinoma patients admitted to Anyang People's Hospital from February 2017 to April 2023 were retrospectively analyzed,and all patients were confirmed to have renal cell carcinoma through pathological examination and underwent magnetic resonance imaging(MRI)plain scan and enhanced scan before treatment.The MRI plain scan and enhanced scan of patients with various subtypes of renal cell carcinoma were compared.Using pathological results as the"gold standard",the differential value of MRI plain scan combined with enhanced scan in pathological subtypes of renal cell carcinoma were evaluated.[Results]The ADC of pRCC and cRCC patients were lower than those of ccRCC patients(P<0.05).The proportion of low and equal signals on T1WI and T2WI plain scans in cRCC patients were higher than those in ccRCC and pRCC patients(P<0.05),while the proportion of mixed signals was lower than that of ccRCC and pRCC patients(P<0.05).The proportion of uneven enhancement in pRCC and cRCC patients were lower than those in ccRCC patients(P<0.05),and the proportion of uneven enhancement in cRCC patients was lower than that in pRCC patients(P<0.05).The enhancement degree distribution of different pathological subtypes were statistically significant(P<0.05),and ccRCC mainly exhibited severe enhancement,and pRCC mainly exhibited moderate enhancement,and cRCC were all mild enhancement patients.The signal intensity changes in cortical,parenchymal and delayed phases of pRCC and cRCC patients were lower than those of ccRCC patients(P<0.05),while the signal intensity changes in all stages of pRCC patients were lower than those in cRCC patients(P<0.05).The sensitivity and accuracy of the combination of MRI plain scan and enhanced scan in ccRCC were higher than those of single identification(P<0.05).The specificity and accuracy of the combination of MRI plain scan and enhanced scan in pRCC were higher than those of single identification(P<0.05),while the sensitivity was higher than that of MRI plain scan alone(P<0.05).The accuracy of combining MRI plain scan and enhanced scan in cRCC was higher than that of single identification(P<0.05).[Conclusion]There are differences in MRI plain and enhanced scan of patients with renal cell carcinoma of different pathological subtypes,and the combination of MRI plain scan and enhanced scan has high value in distinguishing pathological subtypes of renal cell carcinoma.
