Subjects in the developmental arm will have a minimum of two study visits to determine the optimal conditions for visualizing lymphatic transport in the upper extremities. Concentrations of 0.1 mg/ml of Indocyanine Green (ICG) will be injected intradermally into the web spaces of the hands in both upper extremities. Multispectral video and still images will be recorded using the MultiSpectral Imaging System (MSImager). An ultrasound of the upper extremities may be performed after the ICG fluorescence is observed. The exam will help identify the location of the lymphatic vessels and nodes in the areas fluoresced.

Subjects in the clearance arm will have an initial study visit that involves injections of 0.1 mg/ml of Indocyanine Green (ICG) intradermally into the web spaces of the hands in both upper extremities. Multispectral video and still images will be recorded using the MultiSpectral Imaging System (MSImager). Follow up imaging sessions will occur weekly for three weeks for a minimum of four study visits total.

Rheumatoid Arthritis

A trained physician will inject 0.1 ml of Indocyanine Green into the web spaces of the hands in both upper extremities. Subjects may have up to five study visits to confirm feasibility, safety, and reproducibility.

Indocyanine Green

Once the Indocyanine Green is injected, the contrast is expected to fluoresce underneath the MultiSpectral Imaging System. Multispectral video and still images will be recorded at the study visits.

The contraction rate is measured as lymphatic vessel contractions/min in the dominant lymphatic vessel efferent to the injection site using the MultiSpectral Imaging System (MSImager) that captures real time movies. The MSImager software analyses the signal intensity to determine the contraction rate.

The lymphatic pressure is measured using a transparent cuff and the Multispectral Imaging System to determine indirect lymphatic pressure and recorded as mm Hg.

The change in Indocyanine Green signal intensity (arbitrary units) over time is measured by observing the fluorescence using the Multispectral Imaging System. The MSImager software analyses the signal intensity.

Speed with which an Indocyanine Green bolus moves through a lymphatic vessel recorded as mm -sec-1 using the Multispectral Imaging System. The MSImager software analyses the signal speed.

Information of any type may be shared with researchers at other institutions. Subjects will be made aware of this in the informed consent form.
