The Diagnostic Efficacy of Multimodal Imaging in Different Subtypes of Renal Cell Carcinoma and Its Pathological Grading
Objective To analyze the efficacy of multimodal imaging techniques for the diagnosis of different subtypes of kidney cancer and their pathology classification.Methods From January 2021 to January 2023,90 patients with suspected renal cell carcinoma diagnosed by ultrasonography were examined by multimodality CT and MR.To analyze the diagnostic efficacy of CT and MR alone and multimodality CT and MR techniques in suspected renal cell carcinoma.To analyze the relationship between multimodality imaging characteristics and different subtypes,histopathologic grades,and TNM stages of renal cell carcinoma.Results (1)Multimodal imaging in the diagnosis of benign and malignant renal lesions 0.85,the predictive value is strong,with sensitivity and specificity of 98.61%and 94.44%respectively.(2)RCC subtypes were positively correlated with the degree of enhancement and cystic necrosis(r=0.865,0.841,P<0.05).(3)Renal cancer tissue pathology grade was positively correlated with lesion diameter,unclear boundary,apparent intensification,bleeding,and cystic necrosis(r=0.832,0.828,0.826,0.823,0.812,P<0.05).(4)There was no difference in ADC value and rADC value among different subtypes(P>0.05).The ADC and rADC of grade iii were higher than those of grade Ⅰ+ⅱ(P<0.05).0.05).Conclusion Different subtypes,histological grading and TNM staging are related to the enhancement degree of multimodality imaging.Cystic necrosis and other features are related,and multimodal imaging technology has a high value in predicting the nature of kidney cancer,which is conducive to further improving the diagnostic accuracy of the nature,subtype,grade and stage of kidney carcinoma.
