    摘要： Peptide vectors having high KDR binding affinity and processes for making such vectors are provided. The peptide vectors may be conjugated to phospholipids and included in ultrasound contrast agent compositions. Such ultrasound contrast agents are particularly useful in therapeutic and diagnostic methods, such as in imaging KDR-containing tissue and in the evaluation and treatment of angiogenic processes associated with neoplastic conditions. The present invention also provides processes for the large scale production of highly pure dimeric and monomeric peptide phospholipid conjugates as well as precursor materials used to form the conjugates. The present invention further provides processes for the large scale production of highly pure peptide phospholipid conjugates which contain very low levels of TFA.

    摘要： A medical imaging system is proposed. The system includes means for providing a plurality of echo signals indicative of a response of a body part to a plurality of ultrasound pulsed waves having different acoustic pressures, the body part including a tissue being perfused with a contrast agent, and means for discriminating in the echo signals a contribution of a first type of contrast agent from a contribution of a second type of contrast agent and/or of the tissue, at least one harmonic component of the contribution of the first type of contrast agent having an acoustic power changing according to a first dependency law on the acoustic pressure and the at least one harmonic component of the contribution of the second type of contrast agent and/or of the tissue having an acoustic power changing according to at least one second dependency law on the acoustic pressure, wherein the means for discriminating includes means for significantly reducing the at least one harmonic component of the contribution of the second type of contrast agent and/or of the tissue with respect to the at least one harmonic component of the contribution of the first type of contrast agent according to the corresponding dependency laws.

    摘要： Fibrin-binding peptides having high binding affinity and excellent physical characteristics compared to previously known fibrin-binding peptides are provided. These fibrin-binding peptides may be conjugated to a detectable label or a therapeutic agent and used to detect and facilitate treatment of pathological conditions associated with the presence of fibrin such as thrombic, angiogenic and neoplastic conditions. These peptides may be used in imaging processes such as MRI, ultrasound and nuclear medicine imaging (e.g. PET, scintigraphic imaging, etc.). The peptides may also be used therapeutically. The present invention also provides processes and methods for making and using such peptides and conjugates thereof.
