PDFAbstract
Objective To observe the application values of multi-slice spiral CT (MSCT) combined with contrast-enhanced ultrasound (CEUS) in the diagnosis of patients with renal tumors. Methods The clinical data of 68 cases of patients with renal tumors were retrospectively analyzed. All patients were given MSCT and CEUS examinations. The pathological examination was taken as "gold standard" and the diagnostic efficacies of MSCT, CEUS and combined tests were evaluated. Results The sensitivity, accuracy and negative predictive value of MSCT combined with CEUS were higher than those of MSCT in the diagnosis of renal tumors (χ2 =6.993, 5.849, 4.350, P<0.05). The correlation and superiority of MSCT, CEUS and MSCT combined with CEUS in diagnosis of renal tumors were statistically significant, and the positive detection rate of MSCT combined with CEUS was higher than that of MSCT (P<0.05). Conclusion MSCT and CEUS have high sensitivity, specificity and accuracy and obvious images features in diagnosing renal tumors, and the combined diagnosis can help reduce rates of missed diagnosis and misdiagnosis and improve diagnostic accuracy.
