Brief Summary
This study prospectively included 178 patients with bladder neoplastic lesions who planned to undergo surgery (with or without preoperative neoadjuvant chemotherapy). Inclusion criteria: Patients with pathologically confirmed bladder cancer after radical or partial cystectomy or TURBT (\< 2 weeks between surgical resection and imaging). Exclusion criteria: 1) Prior history of chemotherapy and/or radiotherapy; 2) No surgical resection; 3) The interval between surgical resection and imaging examination is \> 2 weeks; 4) Obvious artifacts; 5)MRI scan contraindications. All subjects underwent pelvic MRI. Data was collected using a Siemens VIDA 3TMR scanner (Siemens Healthcare, Erlangen, Germany). All subjects underwent standardized scanning protocols. The obtained images are post-processed and the experimental results are analyzed statistically.

Outcome Measures
Primary Outcomes (1)
quantitative parameters by MRI
quantitative parameters by functional MRI
From the time the participants completed the MRI scan to the post-processing of the resulting images,assessed up to 2 months
Interventions
Functional sequence imaging (MDME, IVIM) sequences were added to the routine MRI scan of patients with bladder tumor
Eligibility Criteria
Patients with bladder neoplasm planned to undergo surgery
You may qualify if:
- Clinical diagnosis of bladder neoplasm
- Must undergo radical or partial cystectomy or TURBT surgery within 2 weeks between surgical resection and imaging
You may not qualify if:
- A history of pelvic radiotherapy or chemotherapy;
- Lack of pathological findings or no surgery;
- The interval between surgical resection and imaging examination \> 2 weeks;
- Poor image quality due to poor coordination or motion artifacts;
- MRI scan contraindications
