Outcome Measures
Primary Outcomes (1)
Improved performance in contrast-enhanced magnetic resonance imaging (MRI) as used for angiography and perfusion
Assessed by comparison of two images made from the raw data set but reconstructed using the standard vs. an alternative algorithm (to be determined during study). Data will be tabulated and analyzed statistically.
Baseline (at enrollment); possible second scan at a later date
Study Arms (1)
Observational
Participants undergo a non-contrast MRI on study and may optionally undergo a second non-contrast MRI on study. Participants may also undergo blood sample collection on study.
Interventions
Eligibility Criteria
Adult male volunteers as well as Mayo patients for whom a prostate MRI exam has been clinically indicated and ordered. In some cases such as for evaluation of the vasculature of the pelvis it may be useful to extend the inclusion criteria of volunteers to adult females.
