Evaluating non-invasive imaging techniques for blood flow assessment

A Pilot Study to Evaluate Multi-Spectral Imaging (MI) and Laser Speckle Imaging (LSI) and Multiphoton Microscopy (MPM) During Vascular Occlusion

University of California, Irvine · NCT01484730

This study is testing new non-invasive imaging techniques to see how well they can measure blood flow changes in the skin when a pressure cuff is applied.

What this trial studies

This research evaluates the performance of non-invasive imaging modalities, specifically Multi-Spectral Imaging and Laser Speckle Imaging, to assess skin blood flow dynamics during vascular occlusion. A pressure cuff will be applied to stimulate changes in blood flow, allowing researchers to measure vascular conditions ranging from ischemia to hyperemia. The study aims to establish the feasibility of these imaging technologies in detecting variations in hemoglobin concentration and blood flow in the skin.

Who should consider this trial

Good fit: Ideal candidates include adult males and females aged 18 years and older with no pregnancy status.

Not a fit: Patients under 18 years of age or those who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance non-invasive diagnostic techniques for assessing vascular conditions, leading to better patient management.

How similar studies have performed: While this approach is innovative, similar imaging techniques have shown promise in other studies, suggesting potential for success.
