Correlation between Ultrasound and CT in the Diagnosis of Bladder Cancer
Introduction: Effective and early diagnosis of bladder cancer is very important to achieve potential treatment and improve the survival rate of affected patients. Objectives: To describe the ultrasonographic and computerized tomography (CT) findings of bladder malignant tumors. Method: An observational, descriptive and cross-sectional study was conducted from January 2013 to December 2017 on 250 patients with bladder cancer who previously underwent ultrasound and CT examinations in the Imaging Department of Saturnino Lora Provincial clinical surgery teaching hospital in Santiago, Cuba. Result: In this series, men over the age of 60 were more commonly diagnosed with bladder cancer. Ultrasound examination showed that in addition to the characteristics of calcification, necrosis, adenosis and infiltration of adjacent structures were observed. Ultrasound examination also showed dominant sonographic structures and clear tumors larger than 3 cm and vascularized tumors. On CT, the mixed structure, space occupying tumor and ultrasonic features were almost identical between the two diagnostic methods. Conclusion: Compared with CT, the sonogram of bladder cancer is mixed and ultrasonic, which makes the diagnosis of the bladder cancer more feasible. However, the features and details displayed by CT were consistent with other imaging techniques.
