Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The overall goal of this study is to investigate the signal intensity and relaxation rate characteristics of gadoterate meglumine (Dotarem, Guerbet, USA) enhanced myocardium during rest and stress perfusion cardiovascular magnetic resonance (CMR) compared to gadobutrol (Gadavist) to prove that Dotarem provides constantly high myocardial relaxation necessary for accurate quantitative perfusion evaluation.

The purpose of this study is to compare two types of contrast that patients receive during cardiac MRI scans to visualize the blood flow in the cardiac muscle. Both contrasts are used in standard of care procedures, and the one administered for each patient will be randomly selected. The length of the MRI study all procedures are the same as the clinically indicated scan.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The overall goal of this study is to investigate the signal intensity and relaxation rate characteristics of gadoterate meglumine (Dotarem, Guerbet, USA) enhanced myocardium during rest and stress perfusion cardiovascular magnetic resonance (CMR) compared to gadobutrol (Gadavist) to prove that Dotarem provides constantly high myocardial relaxation necessary for accurate quantitative perfusion evaluation. Within this overall goal, the following specific aims will be pursued:

* Aim 1: To test the hypothesis that the signal intensity enhancement during Dotarem myocardial stress/rest perfusion is relatively constant, providing linear and stable enhancement in the myocardium, and is not inferior compared to gadobutrol (Gadavist).
* Aim 2: To test the hypothesis that the relaxation rate enhancement during Dotarem myocardial rest perfusion is uniform in the myocardium.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1 - Dotarem

Group 1 (n=30) will receive the clinically approved gadoterate meglumine (Dotarem, 0.1mmol/kg) as the contrast agent for their clinical perfusion study

No interventions assigned to this group

Group 2 - Gadavist

Group 2 (n=30) will receive the clinically approved gadobutrol (Gadavist, 0.1mmol/kg) as the contrast agent.

Gadavist 15Ml Solution for Injection

Intervention Type DRUG

Group 2 (n=30) will receive the clinically approved gadobutrol (Gadavist, 0.1mmol/kg) as contrast agent. The contrast agents will be administered at a flow rate of 5.0 ml/s for both groups. In this study aim, all imaging protocols will comply with standard of care and only the perfusion data will be post-processed and analyzed.
