Brief Summary:
Bladder cancer (BC) as the most common malignancy arising from the urinary tract continues to be a major health problem. This prospective non-randomized study will enroll 150 patients undergoing magnetic resonance imaging (MRI) at different stages of their diagnostic and therapeutical process. The enrolled patients with suspected BC (BC) based on cystoscopy will have their initial MRI examination before transurethral resection of bladder tumor (TUR-BT) and biomarker collection. After pathology review of the histological specimens, patients will be treated according to standard clinical practice. The second MRI examination will be performed before therapeutic intervention, if TUR-BT alone is not sufficient enough. Neoadjuvant chemotherapy will be applied in high risk patients having muscle invasison, while intermediate risk patient - T1 high grade or carcinoma in situ patients - will be treated using Bacillus Calmette-Guerin (BCG) instilliations. After the completion of the neoadjuvant chemotherapy or BCG treatment, the patients will undergo the third MRI examination. Low risk patients will be followed by annual with MRI examination.

Arm Intervention/treatment
Experimental: MRI and biomarkers in bladder cancer
Utilization of MR-imaging and biomarkers to stage bladder cancer and in estimation of chemosensitivity
Device: MR imaging
3 T MRI of the urinary bladder

Primary Outcome Measures :
  1. Accuracy of the multiparametric MRI (anatomical MRI, DCE-MRI, DWI) in the staging of bladder cancer [ Time Frame: 24 months ]
    The accuracy of multiparametric MRI (anatomical MRI, DCE-MRI, DWI) in the staging of bladder cancer will be evaluated using transurethral resection of bladder tumor and cystectomy specimens

Secondary Outcome Measures :
  1. Prediction of response to neo-adjuvant chemotherapy and/or BCG treatment evaluated by multiparametric MRI (anatomical MRI, DCE-MRI, DWI) [ Time Frame: 24 months ]
    The aim is to evaluate predictive power of multiparametric MRI for estimation neo-adjuvant chemotherapy and/or BCG treatment response. Multiparametric MRI will be performed before neo-adjuvant chemotherapy and/or BCG treatment and patients will be followed using standard clinical follow up and/or undergo cystectomy.

Other Outcome Measures:
  1. Estimation of chemosensitivity [ Time Frame: 24 months ]
    Prevalence of patients responding neo-adjuvant chemotherapy, compared with the non-responders as evaluated by cystectomy specimens, according to various biomarkers and ex vivo tissue culturing will be evaluated.
