The Gadolinium-Free MRI Contrast Agent
The Future of Medical Imaging

We all know someone who has had a contrast-enhanced MRI
Over 30 million contrast-enhanced (CE) MRI scans are done worldwide each year.
CE-MRI scans provide vital medical insight informing diagnosis and management of cancer, stroke, multiple sclerosis, myeloma, cardiovascular disease, Crohn's disease and IBD, various genetic disorders, and many other conditions.
Current MRI contrast agents all deposit the heavy metal gadolinium in all patients
All currently approved MRI contrast agents contain the heavy metal gadolinium, which is not naturally found in biology and is toxic in its ionic form. All gadolinium based contrast agents (GBCAs) cause cumulative deposition of gadolinium in the brain, bone, and other organs of all patients. GBCAs also trigger devastating nephrogenic systemic fibrosis in renally impaired patients. Patients at greatest risk include people with renal impairment, children, and people who require repeat CE-MRIs for surveillance, management, or clinical trials.
e.g. BRCA surveillance, multiple sclerosis, cancer, chronic conditions.
Safety concerns led to worldwide regulatory restrictions
Responding to safety concerns, the FDA applied a boxed warning and instituted label changes for all GBCAs. The European Medicines Agency suspended marketing authorizations for the least stable GBCAs and restricted use of other GBCAs. Japan, Korea, Canada, the United Kingdom, and other countries implemented similar restrictions on GBCAs.
No alternatives for crucial contrast-enhanced imaging
CE-MRI provides insights not available using other imaging methods. However, all approved MRI contrast agents are based on gadolinium and face safety concerns. Physicians and patients must make difficult decisions: balancing the need for vital medical imaging with the risks posed by gadolinium.
Reveal’s solution: the gadolinium-free MRI contrast agent
Reveal’s gadolinium-free MRI contrast agent is a direct substitute for GBCAs.
Our agent, RVP-001, is based on the biocompatible essential element manganese.
RVP-001 produces equivalent images to GBCAs for the same indications as GBCAs using established radiology workflow and protocols.
Our goal: safer contrast enhanced MRI for all patients.

Reveal's MRI contrast agent is the gadolinium-free direct replacement for all current GBCAs.

Reveal's MRI contrast agent is designed to be safe for all patients.

Reveal's MRI contrast agent will be the platform for precision imaging.
