Conspectus Contrast agents are used in approximately 40% of all magnetic resonance
imaging (MRI) procedures to improve the quality of the images based on the distribution and …

Contrast-enhanced magnetic resonance imaging (MRI) is an indispensable tool for
diagnostic medicine. However, safety concerns related to gadolinium in commercial MRI …

Early studies suggested that FeIII complexes cannot compete with GdIII complexes as T1
MRI contrast agents. Now it is shown that one member of a class of high‐spin macrocyclic …

Detecting the fluctuation and distribution of various bioactive species in biological systems is
of great importance in determining diseases at their early stages. Metal complex-based …

The presence of multiple oxidation and spin states of first-row transition-metal complexes
facilitates the development of switchable MRI probes. Redox-responsive probes capitalize …

Liposomes containing high-spin Fe (III) coordination complexes were prepared towards the
production of T1 MRI probes with improved relaxivity. The amphiphilic Fe (III) complexes …

In this manuscript, we describe medical applications of each first-row transition metal
including nutritional, pharmaceutical, and diagnostic applications. The 10 first-row transition …

Co (II) complexes of 1, 4, 7, 10-tetraazacyclododecane (CYCLEN) or 1, 4, 8, 11-
tetraazacyclotetradecane (CYCLAM) with 2-hydroxypropyl or carbamoylmethyl (amide) …

The reaction of the synthesized 2‐(4, 5‐diphenyl‐1H‐imidazol‐2‐yl) phenol,(HL) ligand with
FeIII, CoII, NiII, CuII, and ZnII ions at room temperature resulted in the formation of the five …

Fe (III) macrocyclic complexes containing a macrocycle and three pendant groups including
phosphonate (NOTP= 1, 4, 7-triazacyclononane-1, 4, 7-triyl-tris (methylenephosphonic acid) …
