Founded in 1991, ImaRx Pharmaceutical Corp. designs, develops and markets pharmaceuticals for medical imaging (MRI, ultrasound and computed tomography) for the radiological imaging industry. ImaRx Pharmaceutical Corp., announced 1999 that it has been acquired by E.I DuPont de Nemours & Co., Inc. The terms of the acquisition provide a royalty-free licensing arrangement with a newly-formed company, ImaRx LLC ('LLC'), to pursue and develop new products and technologies for drug and gene delivery independent from DuPont. Yamanouchi Pharmaceutical Co. Ltd., ImaRx' licensee for Asian territories for this product, will continue to develop the product in Asia as DuPont's licensee. ImaRx LLC will have ownership of all other targeted and therapeutic products previously owned by ImaRx, including imaging products outside of diagnostic ultrasound imaging and two other imaging products, SonoRx® and LumenHance®, which are both FDA approved and licensed to BRACCO Diagnostics.

A liver sonography is a diagnostic tool to image the liver and adjoining upper abdominal organs such as the gallbladder, spleen, and pancreas. Deeper structures such as liver and pancreas are imaged at a lower frequency 1-6 MHz with lower axial and lateral resolution but greater penetration. The diagnostic capabilities in this area can be limited by gas in the bowel scattering the sound waves. The application of microbubbles may be useful for detection of liver lesions and for lesion characterization. Some microbubbles have a liver-specific post vascular phase where they appear to be taken up by the reticuloendothelial system (RES). Dynamic contrast enhanced scans in a similar way as with CT or MRI can be used to studying the arterial, venous and tissue phase. After a bolus injection, early vascular enhancement is seen at around 30sec in arterialized lesions (e.g., hepatocellular carcinomas (HCC), focal nodular hyperplasia (FNH)). Later enhancement is typical of hemangiomas with gradually filling towards the center. In the late phase at around 90sec, HCCs appear as defects against the liver background. Most metastases are relatively hypovascular and so do not show much enhancement and are seen as signal voids in the different phases. Either with an intermittent imaging technique or by continuous scanning in a nondestructive, low power mode, characteristic time patterns can be used to differentiate lesions.

(MIP) Angiography (Doppler) images can be processed by Maximum Intensity Projection to interactively create different projections. Although the maximum intensity projection (MIP) post processing algorithm is sensitive to high signal from inflowing spins as used in MRI, it is also sensitive to high signal of any other etiology as used in ultrasound imaging. The MIP connects the high intensity dots of the blood vessels in three dimensions, providing an angiogram that can be viewed from any projection. Each point in the MIP represents the highest intensity experienced in that location on any partition within the imaging volume. For complete interpretation the base slices should also be reviewed individually and with multiplanar reconstruction (MPR) software. The MIP can then be displayed in a CINE format or filmed as multiple images acquired from different projections. See also 3D Ultrasound. •
Molecular Biosystems, Inc. (MBI), founded in 1980, is a biomedical company developing a range of contrast agents for use with diagnostic ultrasound, magnetic resonance imaging (MRI), and computed tomography (CT). Alliance Pharmaceutical Corp. acquires Molecular Biosystems in Nov. 2000. Result Pages : | Share This Page     Look Ups |
