Acoustic properties of ultrasound contrast agents

Abstract

textabstractSafety of contrast agents is reported in the years after. Both the intracoronary use of sonicated Renografin as well as intravenous use of commercial product as Albunex and Lechovist has been investigated. Thereafter more pathophysiologic studies were performed. Ten Cate described the possibilities to determine the stenosis of the left anterior descending coronary artery by the contrast outwash in the interventricular septum and Cornel who incidentally reported the Thebesian vein outflow in humans visualised by echo contrast. Cheiriff and his group described myocardial perfusion studies to determine coronary flow reserve before and after Percutaneous Transluminal coronary angioplasty (PTCA). Coronary collateral perfusion after myocardial infarction or PTCA can be assessed. Also, successful thrombolysis, resulting in a patent coronary artery, is often not accompanied by a return of normal perfusion or wall motion
