Context examples:
An enhancing lesion is a well-demarcated area of unequivocally increased signal intensity on T1-weighted spin-echo (SE) images compared with normal-appearing, surrounding tissue following intravenous injection of a gadolinium chelate.
(Enhancing Lesion, NCI Thesaurus)
A paramagnetic contrast agent consisting of the disodium salt of the gadolinium ion chelated with the lipophilic moiety ethoxybenzyl (EOB) bound to diethylenetriamine pentaacetic acid (DTPA).
(Gadoxetate Disodium, NCI Thesaurus)
Gadobutrol is a non-ionic, paramagnetic complex consisting of gadolinium (Gd3+) chelated with the macrocyclic compound dihydroxy-hydroxymethylpropyl-tetraazacyclododecane-triacetic acid (butrol).
(Gadobutrol, NCI Thesaurus)
The antibody would bind to a specific target – a metastatic melanoma cell, for example – while the gadolinium would increase the magnetic signal detected by the MRI scanner.
(Imaging Contrast Agent, The Titi Tudorancea Bulletin)
A coordination complex consisting of a gadolinium ion bound to a hexadentate organic chelating agent such as diethylenetriaminepentaacetic acid.
(Gadolinium-Chelate, NCI Thesaurus)
Also called motexafin gadolinium.
(Gadolinium texaphyrin, NCI Dictionary)
When placed in a magnetic field, gadolinium produces a large magnetic moment and so a large local magnetic field, which can enhance the relaxation rate of nearby protons; as a result, the signal intensity of tissue images observed with magnetic resonance imaging (MRI) may be enhanced.
(Gadoxetate Disodium, NCI Thesaurus)
Also called gadolinium texaphyrin.
