Purpose:
The purpose of this study was to evaluate the performance of spiral CT and MRI in patients with bladder tumor.
Materials And Methods:
In this study, patients with suspected urinary bladder tumor were evaluated by abdominal CT and MRI. This study included 32 patients. In 23 cases, transurethral resection (TUR), and in 9 cases radical cystectomy was performed. Additionally, pelvic lymph node dissection was performed in 9 patients.
Results:
According to the pathological results of TUR-performed patients; the accuracy of spiral CT and MRI in preoperative staging of bladder tumors was 41.6% and 83.3%, respectively. The accuracy of spiral CT and MRI in preoperative staging of bladder tumors were 66.6% and 77.7% in patients who underwent radical cystectomy. Pelvic lymph node involvement was evaluated properly with MRI and CT.
Conclusion:
In the preoperative staging of bladder tumors, MRI is superior to CT. The superiority is more definite especially in early stage tumors.
