Radiometals comprise many useful radioactive isotopes of various metallic elements. When
properly harnessed, these have valuable emission properties that can be used for …

The simplest reaction on a metal ion in aqueous or nonaqueous solution is the exchange of
a solvent molecule between the first and second coordination shells (eq 1). This reaction is …

Magnetic resonance imaging (MRI) is a non-invasive clinical imaging modality, which has
become widely used in the diagnosis and/or staging of human diseases around the world …

Magnetic resonance imaging (MRI) contrast agents that contain the gadolinium ion are
widely used in biomedical research and diagnosis. The relaxation mechanism of these T1 …

Cancer is a known deadliest disease that requires a judicious diagnostic, targeting, and
treatment strategy for an early prognosis and selective therapy. The major pitfalls of the …

We have investigated novel bifunctional chelate alternatives to the aminocarboxylate
macrocycles NOTA (N3O3) or DOTA (N4O4) for application of radioisotopes of Ga to …

The positron-emitting radionuclide gallium-68 has become increasingly utilised in both
preclinical and clinical settings with positron emission tomography (PET). The synthesis of …

We report a new macrocyclic ligand, N, N′-bis [(6-carboxy-2-pyridil) methyl]-4, 13-diaza-18-
