Abstract:
Purpose To compare the value of contrast-enhanced ultrasound (CEUS), contrast-enhanced CT (CECT) and contrast-enhanced MRI (CEMRI) in the diagnosis of renal space-occupying lesions. Materials and Methods Seventy-eight patients whose 80 kidney space-occupying lesions were conifrmed by traditional ultrasound underwent CEUS examination. Among those patients, 39 patients also underwent CECT, 28 had CEMRI, and 5 had CECT and CEMRI examination together. Taken pathologic findings as gold standard, the value of conventional ultrasound, CEUS, CECT and CEMRI was compared in the diagnosis of renal space-occupying lesions. Results Among 80 renal masses, 57 lesions were malignant and the rest 23 lesions were benign. The diagnostic sensitivity, speciifcity, positive predictive value and negative predictive value were 93.0%, 69.6%, 88.3%, 80.0%for CEUS;those for CECT were 96.4%, 72.7%, 90.0%, 88.9%respectively;and for CEMRI were 86.4%, 66.7%, 90.5%, 57.1%respectively;and the diagnostic value among the three means showed no difference (P>0.05). Conclusion CEUS, CECT and CEMRI are all effective in the diagnosis of renal space-occupying lesions, We may select suitable examination means for patients according to their features. A combination of these techniques provides more information for the diagnosis of renal space-occupying lesions.
