Multiparametric MRI for Bladder Cancer: Validation of VI-RADS for the Detection of Muscle Invasive Bladder Cancer

Multiparametric MRI for Bladder Cancer: Validation of VI-RADS for the Detection of Muscle Invasive Bladder Cancer

This research aimed to determine how accurately multiparametric magnetic resonance imaging (MRI), when interpreted using the VI-RADS scoring system, can distinguish between invasive and non-invasive bladder cancer.

Bladder cancer (BC) is among the most widespread malignancies needing management. The majority of bladder cancers are urothelial cell carcinomas, which are further classified histologically into low-grade and high-grade categories.

Multiparametric magnetic resonance imaging (mpMRI), a recent advancement in MRI technology, combines functional sequences like DWI and DCE-MRI with anatomical T1- and T2-weighted images. This integrated approach enhances tumor detection and staging accuracy, aids in post-therapy response monitoring, and facilitates the identification of local disease recurrence.

Inclusion Criteria:

• Both sexes.
• Patients with bladder masses diagnosed through ultrasound, computed tomography, or magnetic resonance imaging (MRI), who were scheduled for cystoscopy.

Exclusion Criteria:

• Contraindications to MRI (such as metallic prostheses or pacemakers).
• Contraindications to Transurethral Resection (like unfitness for anesthesia or urethral strictures).
• Elevated serum creatinine levels (precluding IV contrast-enhanced imaging).
