Short name: P792, generic name: Gadomeritol
A macromolecular Gd-DOTA derivate under development (phase II, Guerbet SA) as a positive enhancing blood pool agent (MRI contrast agent) for, e.g. myocard perfusion and tumor characterization.

GE Medical Systems and Amersham announced in April 2004 the completion of a share exchange acquisition of Amersham Health by GE. The result of this acquisition is the new GE Healthcare, based in the UK, totally owned by General Electric (GE).

Amersham Health, was the imaging diagnostics and therapy business of Amersham plc.

The rapid improvements in instrumentation, which have added benefit to the use of extracellular fluid agents such as Omniscan™, have also diminished the market potential for blood pool products such as Clariscan™. As a consequence, Amersham decided to discontinue the development of Clariscan™.

ABLAVAR™ (formerly named Vasovistâ„¢) is a blood pool agent for magnetic resonance angiography (MRA), which opens new medical imaging possibilities in the evaluation of aortoiliac occlusive disease (AIOD) in patients with suspected peripheral vascular disease.
ABLAVARâ„¢ binds reversibly to blood albumin, providing imaging with high spatial resolution up to 1 hour after injection, due to its high relaxivity and to the long lasting increased signal intensity of blood.
As with other contrast media: the possibility of serious or life-threatening anaphylactic or anaphylactoid reactions, including cardiovascular, respiratory and/or cutaneous manifestations, should always be considered.

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.
