Participants cannot have any serious diseases or disorders that affect your ability to participate in this study. Women who are pregnant or plan to become pregnant during the study cannot be included. The investigators will ask females of child-bearing potential to undergo a urine pregnancy test prior to any procedures (such as MRI, x-ray, fluoroscopy) that may disrupt the healthy development of an unborn child. If participants are currently taking any medications that thin their blood, participants will not be eligible for this study. Participants will have to meet other criteria to be eligible, which will be reviewed with participants upon their consent. The investigators will screen 15 people and expect that up to 10 individuals will complete this study.
