Phenotyping Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) by Intravesical Contrast Enhanced - Magnetic Resonance Imaging (ICE-MRI) Bladder Permeability Assay

After fully emptying the bladder with a catheter,1.5mg of Ferumoxytol combined with Gadobutrol 302 mg will be instilled into the bladder through the catheter. The catheter will be plugged, and the patient will submit to an MRI scan of the bladder. After the MRI is completed, the Ferumoxytol will be drained through the catheter and the catheter will be removed.
