About IMCOR

IMCOR Pharmaceutical Co. is a specialty pharmaceutical company developing and marketing a platform of innovative imaging products. Its FDA approved product, Imagent, is indicated for use in patients with suboptimal echocardiograms to opacify the left ventricle and thereby improve visualization of the main pumping chamber of the heart, and to improve delineation of the endocardial borders (walls) of the heart. As a result, ultrasound with Imagent may better distinguish normal and abnormal heart structure and function -- two critical indicators of cardiac health. Imagent is also being investigated to measure myocardial perfusion to determine the location and extent of blockage of the major coronary arteries. Imagent is manufactured from synthetic materials, and packaged as a dry powder in a ready-to-use kit that is stored at room temperature. IMCOR's development programs include the use of a versatile iodinated nanoparticulate formulation, PH-50 that shows promise as a CT cardiovascular imaging agent and lymphography imaging agent.
