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.
