Two new Gd(III) complexes based on 5-aryl-2,2’-bipyridines with the DTTA residue at C6’ position were obtained. Primary photophysical properties of chelates have been studied. The resulting are interest by potential using, e.g., as contrast reagents for magnetic resonance imaging (MRI).

T he article “High signal intensity in the dentate nucleus and globus pallidus on unenhanced T1weighted images: evaluation of the macrocyclic gadolinium-based contrast agent gadobutrol” by Radbruch et al provides critical new information regarding gadolinium deposition in the dentate nucleus. The conclusion, from a study of 30 patients, is that no signal intensity increase is seen with gadobutr...

OBJECTIVES The purpose of this study was to examine the potential of intravascular gadolinium (Gd)-chelates in discriminating acute from chronic myocardial infarctions (MIs). BACKGROUND A potential limitation of delayed contrast enhanced magnetic resonance imaging with standard extracellular Gd-chelates is its inability to distinguish acute from chronic MIs. METHODS Eight pigs with MIs were...
