Detailed Description

PRIMARY OBJECTIVE:

I. To study how a variety of technological approaches in MRI can be used to provide improved performance contrast-enhanced MR imaging as used for angiography and perfusion as well as in MR image acquisition without the use of contrast material.

OUTLINE: This is an observational study.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Probability Sample

Study Population

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.

Description

Inclusion Criteria:

  • Adults

Exclusion Criteria:

  • Standard exclusion criteria for clinical MRI; e.g. cardiac pacemaker, claustrophobia, an implanted device that has been determined to be MR conditional at 1.5T but not at 3T, anticipated considerable susceptibility artifact from hip prosthesis, etc.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Improved performance in contrast-enhanced magnetic resonance imaging (MRI) as used for angiography and perfusion
Time Frame: Baseline (at enrollment); possible second scan at a later date
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
