Comparison of the high relaxivity Gd chelates P1152 and Gd-BOPTA for contrast-enhanced MR angiography in rabbits at 1.5 Tesla and 3.0 Tesla.

Purpose: To compare signal-enhancing properties of the high relaxivity Gd chelates P1152 and Gd-BOPTA for contrast-enhanced MR angiography (CE-MRA) in rabbits at 1.5 Tesla (T) and 3.0T.

Contrast-enhanced magnetic resonance angiography: evaluation of the high relaxivity low diffusible gadolinium-based contrast agent P846 in comparison with gadoterate meglumine in rabbits at 1.5 Tesla and 3.0 Tesla.

Objectives: To evaluate the gadolinium-based contrast agent P846 and compare it with gadoterate meglumine (Gd-DOTA) for contrast-enhanced magnetic resonance angiography (MRA) in rabbits at 1.5 T and 3.0 T, respectively.
