- W2389621567 abstract "Objective To evaluate the diagnostic value of renal tumor with 3D CPA. Methods Forty six patients with different pathological types of renal tumors were examined with 3D CPA.The vascular pattern of renal tumor and vascularity index(VI) were assessed. Results Twenty six of the 36 renal malignant tumors were 3D CPA III,10 of which were 3D CPA II.Six of 10 renal benign tumors appeared 3D CPA I,4 of which appeared 3D CPAII.Using the vascular pattern of 3D CPA III,the sensitivity and specificity in diagnosing renal cell carcinoma were 72.2% and 100% respectively.VI was ( 0.3418 ± 0.1556 ) counts/cm 3 in kidney malignant tumors and was (0.1948±0.0573) counts/cm 3 in kidney benign tumors.There was significant difference between VI of malignant and benign tumors.Using the VI more than 0.25 counts/cm 3 as a standard,the sensitivity and specificity in diagnosing kidney malignant tumor were 77.8% and 80% respectively. Conclusion 3D CPA could show overall vascular perfusion of different renal tumors clearly.Vascular pattern and VI of 3D CPA are helpful to diagnose and differentiate renal tumors." @default.
