Abstract

Although Gadolinium-diethylene triamine penta-aceticacid (GdDTPA) has been used as a contrast material in magnetic resonance imaging (MRI), its contrast enhancement effect is not uniform at high concentrations. In order to evaluate the proper pulse sequences for dynamic MRI in aqueous solutions of Gd-DTPA, blood samples, and a MELANOMA cell line, the SIGNAL INTENSITY for several concentrations of Gd-DTPA were measured under inversion recovery (T1-weighted) at high magnetic field strength (7.0 Tesla). For aqueous solution of GdDTP A, SIGNAL INTENSITY linearly correlated with the concentration of Gd-DTPA between 0 and 4 mM. Using blood and a MELANOMA cell line, SIGNAL INTENSITY was nonlinearly correlated with the concentration of GD-DTP A between 0 to 1.5 mM. For concentrations of more than 4 mM in aqueous solutions of GD-DTP A, 1 mM in blood, and 1.5 mM in MELANOMA, SIGNAL INTENSITY decreased with increase of GD-DTP A concentration.
