Detailed Description

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

In this study, the diameter of each subjects' radial artery will be measured using MRI imagery at varying degrees of radial artery compression by adjusting the amount of air injected into a Terumo TR Band. In addition, using pulse oxymetry, the perfusion waveform will be measured and recorded also while the subjects have a TR Band in place on their wrists.

Study Groups

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

TR Band

Each subject will have a Terumo TR Band applied to the wrist with MRI scans done at differing band pressure levels. The diameter of the radial artery will be measured at each level of band compression.

Group Type EXPERIMENTAL
