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

May 5, 2026 updated by: Islam Mohamed Mohamed, Ain Shams University
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.

Detailed Description

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.

Study Population

This cross-sectional study involved 60 patients with bladder masses diagnosed through ultrasound, computed tomography, or magnetic resonance imaging (MRI), who were scheduled for cystoscopy. The study was carried out with approval from the Ethical Committee at our institute. Informed written consent was obtained from all participants.

Description

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).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Sensitivity of VI-RADS score for invasion through the bladder wall
Time Frame: 3 months after the procedure

Sensitivity of VI-RADS score for invasion through the bladder wall was recorded.

At the end VI-RADS scoring was calculated using all categories, to know the probability of muscle invasion as follows: VI-RADS 1 (very low probability of muscle invasion ): SC, CE, and DW category 1; VI-RADS 2 (low probability of muscle invasion): SC, CE, and DW category 2; both CE and DW category 2 with SC category 3; VI-RADS 3 (muscle invasion is equivocal): SC, CE, and DW category 3; SC category 3 and CE or DW category 3, with the remaining sequence in category 2; (Category 3 should be applied when category 2 findings are absent in their respective sequences but there is no apparent disruption of the typical SI in the muscularis propria, there may be Misclassifications in the VI-RADS 2-3 group).
