Brief Summary
This is a phase Ib study of the safety and performance of a novel intravesical contrast-enhanced Magnetic Resonance Imaging protocol for determination of bladder cancer stage prior to transurethral resection of bladder tumor (21 subjects) or prior to radical cystectomy for muscle invasive disease (21 subjects). Subjects will undergo a single MRI study: a pre-contrast, single breath hold image followed by sterile placement of a temporary urethral catheter for instillation of a 50mL solution containing Gadobutrol (4 mM) plus ferumoxytol (5 mM) and then a second, post-contrast image. Images will be reviewed by two dedicated abdominal radiologists, who are blinded to the pathologic staging, for determination of tumor presence and depth of bladder wall penetration.

Outcome Measures
Primary Outcomes (1)
Accuracy of Magnetic Resonance Imaging assessment of depth of bladder wall penetration to predict pathologic stage determined at tumor resection
The assessment of clinical tumor stage assigned by the radiologist will be compared to the stage reported by the clinical pathologist following tumor resection to determine the overall accuracy of MRI for bladder cancer staging.
4 weeks
Secondary Outcomes (2)
Accuracy of Magnetic Resonance Imaging to detect residual/recurrent bladder tumor
4 weeks
Rate of Adverse Events

Study Arms (1)
Magnetic Resonance Imaging
EXPERIMENTALPrior to planned surgical resection, subjects will undergo a single Magnetic Resonance Imaging study: a single breath-hold pre-contrast image followed by sterile placement of a temporary urethral catheter for instillation of a 50mL solution containing Gadobutrol (4 mM) plus ferumoxytol (5 mM) and a second, single breath hold post-contrast image.
Interventions
60-cm wide bore 3T scanner (Siemens AG, Erlangen, Germany) with a 32-channel pelvic phased-array coil placed over the bladder.
A paramagnetic macrocyclic gadolinium-based contrast agent administered intravenously for use in magnetic resonance imaging. Contrast-enhancement is a result of the neutral complex of gadolinium and dihydroxy-hydroxymethylpropyl- tetraazacyclododecane-triacetic acid (butrol).
An iron preparation (Fe3O4) approved for intravenous treatment of anemia in the setting of renal failure, comprised of superparamagnetic iron oxide nanoparticles which are coated by a semi-synthetic carbohydrate shell in an isotonic, neutral pH solution.
Eligibility Criteria
You may qualify if:
- to 90 years of age
- Able to understand and willing to sign a written informed consent document
- A papillary tumor identified by cystoscopy that has been scheduled for TURBT OR histologically proven MIBC that is clinically localized and amenable to surgical resection with curative intent.
- Performance status of ECOG 0 or 1
- Normal renal function as defined as creatinine less than 1.5 x institutional upper limit of normal (ULN) OR creatinine clearance greater than or equal to 50 mL/min/1.73 m2 by Cockcroft-Gault formula for subjects with creatinine levels greater than or equal to 1.5 x ULN.
You may not qualify if:
- Severe hypersensitivity reaction to gadobutrol or ferumoxytol.
- Severe claustrophobia that will prevent completion of the MRI study.
- Any MRI-non-compatible implanted device, prosthetic or pacemaker.
- Known or suspected metastatic disease.
- Women with active pregnancy, lactation or plans to conceive
- Untreated urinary tract infection
- Known urethral stricture disease that would prohibit placement of foley catheter.
- Any other conditions considered as unacceptable risk by the treating physician

Data Sharing
- IPD Sharing
- Will not share
1. What data will be shared? The investigators will share the accuracy of the MRI staging versus the traditional pathological staging. 2. Who will have access to the data? The investigators and future researchers who provide the proper MTA, IRB, etc. will have access to the de-identified data. 3. Where will the data to be shared be located? De-identified data will be kept on the UPMC cloud. 4. When will the data be shared? The data will be available to share after final analysis and publication of results. 5. How will researchers locate and access the data? A link to the Cloud folder will be provided.
