MultiHance® is a paramagnetic contrast agent for use in diagnostic magnetic resonance imaging (MRI) of the liver and central nervous system. MultiHance® is a small molecular weight chelate, which tightly binds the Gd atom. The substance is excreted partly by the kidneys, partly by the biliary system, which is especially unique.
MultiHance® is indicated, for the detection of focal liver lesions in patients with known or suspected primary liver cancer (e.g. hepatocellular carcinoma) or metastatic disease.
MultiHance® is also indicated in brain MRI and spine MRI where it improves the detection of lesions and provides diagnostic information additional to that obtained with unenhanced MRI.
Gd-BOPTA-enhanced MRA can provide superior vascular signal intensity and SNR, as compared with Gd-DTPA, due to its higher relaxivity, even at lower doses.
1 ml of solution MultiHance® contains: (0.5M) gadobenate dimeglumine 529 mg = gadobenic acid 334 mg + meglumine 195 mg. Viscosity at 37°C: 5.3 mPa

WARNING: NEPHROGENIC SYSTEMIC FIBROSIS Gadolinium-based contrast agents increase the risk for nephrogenic systemic fibrosis (NSF) in patients with acute or chronic severe renal insufficiency (glomerular filtration rate less than 30 mL/min/1.73m²), or acute renal insufficiency of any severity due to the hepato-renal syndrome or in the perioperative liver transplantation period.

Omniscan® is a nonionic chelate complex with low osmolality used as a paramagnetic MRI contrast agent. The efficacy of Omniscan® is similar to that of Gd-DTPA. Omniscan® is given intravenously to enhance images of intracranial and spinal lesions where there is abnormal vascularity or an abnormal blood brain barrier. The complex does not cross an intact blood brain barrier so Omniscan® only accumulates in lesions such as neoplasm's and abscesses.

OptiMARK® is a formulation of a nonionic gadolinium chelate of diethylenetriamine pentaacetic acid bismethoxyethylamide (gadoversetamide), for use as a paramagnetic MRI contrast agent. OptiMARK® (gadoversetamide injection) is to be administered by intravenous injection. OptiMARK® is indicated for MRI diagnostic procedures to provide increased enhancement and visualization of lesions of the brain, spine and liver, including tumors.

ProHance® consists of a nonionic gadolinium complex (Gadoteridol) used as a paramagnetic MR contrast agent.
ProHance® provides contrast enhancement of the brain, spine and surrounding tissues resulting in improved visualization (compared with unenhanced MRI) of lesions with abnormal vascularity or those thought to cause a disruption of the normal blood brain barrier. ProHance® can also be used for whole body contrast enhanced MRI including the head, neck, liver, breast, musculoskeletal system and soft tissue pathologies.

Vasovistâ„¢ is an albumin-targeted intravascular contrast agent. It is indicated for contrast enhanced MR angiography (CE-MRA) for the visualization of abdominal or limb vessels in patients with suspected or known vascular disease. After IV injection, Vasovistâ„¢ binds reversibly to human albumin in plasma, which results in long-lasting increased relaxivity. Imaging from 5 to 50 min is possible. A small unbound portion is, by glomerular filtration, eliminated by the kidneys.
AngioMARK® was the formerly trade name and MS-325 the research name. Currently the phase III clinical trials are completed to determine its efficacy for peripheral vascular disease and coronary artery disease.
In the U.S., EPIX received an approvable letter from the U.S. Food and Drug Administration (FDA) for Vasovistâ„¢ in January 2005. In 2009, Epix Pharmaceuticals has sold the U.S., Canadian and Australian rights for its blood pool agent (now named ABLAVARâ„¢), to Lantheus Medical Imaging, Inc..
