- W2373264496 abstract "Objective To evaluate the usefulness of apparent diffusion coefficients (ADC) for differentiating benign from malignant renal lesions,and characterizing solid tumors,necrotic or cystic tumor areas and simple cysts. Materials and Methods The renal magnetic resonance (MR) imaging data including diffusion-weighted imaging of sixty cases including 50 cases renal masses and 10 cases normal volunteers were analyzed. Twenty-four cases of malignant and 6 case of benign masses were proved by operation,two cases of metastasis and 18 case of benign lesions were proved by clinical data and other diagnostic imageology examinations. The raw data of DWI were transmitted to the workstation to generate the corresponding maps of ADC. ADC values of whole lesions, soft tissue and necrotic or cystic areas were measured. The normal renal parenchyma was measured at the boundary of cortex and medulla at the level of renal hilum. Results The ADC values had significant difference among the normal renal,the benign masses and the malignant masses,P0.05;The renal tumors had significantly lower ADC value compared with the benign cysts,P0.05;The area of solid enhancing tumor tissue had significantly lower ADC value than nonenhancing necrotic or cystic areas,P0.01;The necrotic or cystic areas within the renal tumors had significantly lower ADC value than benign cysts,P0.01. Conclusion DW imaging can be used to characterize renal masses;The T1 signal characteristics of a renal lesion appear to be related to the ADC of the lesion,and may be helpful in characterizing and differentiating renal masses." @default.
