Magnetic Resonance Imaging (MRI) to Assess Radial Artery Compression and Arterial Perfusion While TR Band is Applied

Terumo

Status: Completed

Conditions: Poor Peripheral Perfusion

Treatments: Device: TR Band

Study type: Interventional

Funder types: Other; Industry

Identifiers

TIS2015-002

Details and patient eligibility

About

Subjects' radial artery diameters and plethysmography waveforms will be recorded by MRI and pulse oxymetry at varying levels of radial artery compression by the Terumo TR Band.

Full description

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.

Description:

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.
