Transient Severe Arterial Phase Motion
Conditions
Brief summary
The purpose of this study is to evaluate changes in volunteer breath-holding capacity in response to gadoxetate disodium (Eovist) administration, compared with saline, and gadoterate dimeglumine (Dotarem). Healthy volunteers will be recruited from three study sites. These subjects will be given three, blinded, randomized injections while undergoing an MRI of their liver and holding their breath. During the scan, the subjects' oxygen saturation and heart rate will be closely monitored. Following the scan, the subjects will complete a questionnaire regarding the breath hold.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Subject Breath Hold Capacity, as Measured by Number of Seconds a Subject Can Hold His/Her Breath | following contrast administration, up to 5 minutes | — |
| Subject-reported Dyspnea, as Measured by Questionnaire Responses | following contrast administration, up to 5 minutes | After each breath-hold, the MRI technologist asked the volunteer through the scanner microphone the following two questions, with responses based on a 5-point scale: A) How difficult was it to hold your breath? (1-Not at all; 5-Very difficult); B) Do you feel short of breath now? (1-Not at all; 5-Very short of breath). Responses were recorded for each breath-hold. |

Time frame: following contrast administration, up to 5 minutes
Population: All participants received all three drugs.
| Arm | Measure | Value (MEDIAN) |
|---|---|---|
| Eovist (Gadoxetate Disodium) | Subject Breath Hold Capacity, as Measured by Number of Seconds a Subject Can Hold His/Her Breath | 28 seconds |

Subject-reported Dyspnea, as Measured by Questionnaire Responses
After each breath-hold, the MRI technologist asked the volunteer through the scanner microphone the following two questions, with responses based on a 5-point scale: A) How difficult was it to hold your breath? (1-Not at all; 5-Very difficult); B) Do you feel short of breath now? (1-Not at all; 5-Very short of breath). Responses were recorded for each breath-hold.
Time frame: following contrast administration, up to 5 minutes
