What is Update on multiparametric MRI of urinary bladder cancer: MRI of Urinary Bladder Cancer about?

While many institutions perform mri during the work-up of urinary bladder cancer, others use mri rarely if at all, possibly due to a variation in the reported staging accuracy and unfamiliarity with the potential benefits of performing mri. through increased application of functional imaging techniques including diffusion-weighted imaging (dwi) and dynamic contrast-enhanced (dce) imaging, there has been a resurgence of interest regarding evaluation of bladder cancer with mri. several recent meta-analyses have shown that mri is accurate at differentiating between ≤t1 and t2 disease (with pooled sensitivity/specificity of ∼90/80%) and differentiating between t2 and ≥t3 disease. dwi and dce, in combination with high-resolution t -weighted images, improves detection and possibly local staging accuracy of bladder cancer. high b value echo-planar dwi is particularly valuable for tumor detection. zoomed field of view and segmented readout dwi techniques improve image quality by reducing susceptibility artifact, while methods to extract calculated high b value images save time and improve the contrast-to-noise ratio. dce traditionally required imaging of the pelvis with high temporal but l
