Abstract

Background :Carcinoma of the urinary bladder is a common malignant tumor of the urinary tract. Proper management of the urinary bladder cancer depends on the stage of the lesions. Cases with muscle invasive bladder carcinoma (MIBCs) are treated with neoadjuvant chemotherapy, radical cystectomy, and lymphadenectomy while in non-muscle invasive bladder carcinoma (NMIBCs) transurethral resection + chemo/immunotherapy . The aim of this prospective study was to determine the accuracy of high resolution T2 & diffusion-weighted images in early detection of muscle invasion, local tumor staging of urinary bladder carcinoma and to measure the correlation between the apparent diffusion coefficient (ADC) and histologic grade.

Methods:25 cases of urinary bladder cancer were enrolled in this study before undergoing transurethral cystoscopy and biopsy.

Results :the study involved 25 pateints with urinary bladder mass lesion. Their age ranged from47 to 74 years with mean (64.08) years ± standard deviation (7.49) years. The study included 21 males (84%) and 4 females (16%), combination of T2WI and DWI provide better assessment of muscle invasion than using T2 alone.
