Summary
This summary is machine-generated.Multiparametric MRI (mpMRI) with VI-RADS scoring effectively rules out muscle invasion in bladder cancer. Further research can improve its accuracy for detecting invasive bladder tumors, aiding patient selection for diagnosis and treatment.
Area Of Science
- Urology
- Radiology
- Oncology
Background
- Accurate local staging of bladder tumors is crucial for effective treatment planning.
- Multiparametric MRI (mpMRI) is an emerging tool for bladder cancer assessment.
Purpose Of The Study
- To evaluate the accuracy of preoperative mpMRI using the Vesical Imaging Reporting and Data System (VI-RADS) for local staging of bladder tumors.
- To compare mpMRI findings with histopathological results to determine clinical efficacy.
Main Methods
- 63 patients with suspected bladder tumors underwent mpMRI between November 2020 and April 2022.
- mpMRI images were analyzed using VI-RADS criteria.
- Radiological findings were compared with subsequent histopathological examination of biopsies.
Main Results
- 84% of tumors were classified as muscle-invasive by VI-RADS (>3), while histopathology confirmed invasion in 52% of cases.
- VI-RADS demonstrated 100% sensitivity and 100% negative predictive value for muscle invasion.
- Specificity was 23% and positive predictive value was 62% for detecting muscle invasion.
Conclusions
- The VI-RADS scoring system via mpMRI is highly effective in excluding muscle invasion in bladder cancer.
- Further studies are needed to enhance the detection of muscle invasion, potentially improving diagnostic efficiency.
- VI-RADS can assist in selecting patients for precise diagnosis and appropriate treatment strategies.
