Abstract

Background: The Vesical Imaging–Reporting and Data System (VI-RADS) could be
a recently created framework of the bladder.cancer staging usingmultiparametric MRI
(mpMRI), which can be utilized to anticipate the nearness of invasion of the bladder wall
muscle in cases of cancer of the bladder.
Aim: The aim.of the study isto defineVI-RADS as a standard approach of imaging and
reporting systemusing mpMRI with T2-weighted imaging (T2WI), diffusion-weighted
imaging (DWI), and dynamic contrast-enhanced imaging (DCE MRI) for accurate Bladder
Cancer staging.
Method:The study was done in ZagazigUniversity Hospital. Eighty patients with lower
urinary tract symptoms and urinary bladder mass detected by ultrasound were scheduled for
elective multiparametric magnetic resonance imaging in the period from February 2020 to
January 2021.
Results:In our study,low-grade bladder cancer regarding histopathological grading
represented a higher percentage than tumors of high-grade type with 56.6%, and according to
mp MRI, we had 46 patients with NMIBC representing 60.5 % while VIRADS distribution
among 76 patients with bladder cancer was as follow V1=12, V2=26, V3=10, V4= 14,
V5=14 cases respectively and we founda highly statistically significant association between
tumor histopathological grading and mp MRI where P value < 0.001
Conclusion:This study has shown thatthe score related to VIRADSshows up to be a good
and impressiveradiological methodthat can be used before the operation for the definition and
prediction of invasion of the detrusor muscle (NMIBC vs. MIBC) in bladder cancer
usingmpMRI.

Key words: Neoplasms; urinary bladder; Anatomicaland functional magnetic resonance imaging; Diffusion-weighted imaging; Imaging with administration; Validity of results.
