Brief Summary
Lymphatic transport will be examined using Near InfraRed Indocyanine Green fluorescence imaging (NIR-ICG) and magnetic resonance lymphography (MRL) of the upper extremities. The purpose of the study is to establish if NIR-ICG is a valid clinical outcome for quantifying lymphatic vessel drainage.

Outcome Measures
Primary Outcomes (3)
Manual lymphatic vessel counts via assessment of 2D images of NIR-ICG compared to MRI. Unit of measure: # lymphatic vessels/hand
Vessel location and numbers will be identified using 2D still images from the NIR scanning sessions and with 2D MR images. These images will be superimposed upon each other in order to confirm concordance of lymphatic vessels. Number of lymphatic vessels in the hands will be manually counted.
12 months
Lymphatic contraction rate measured via NIR ICG camera. Unit of measure: # contraction/minute
Images collected from NIR scanning sessions will be analyzed to determine lymphatic contraction rate by identifying number of contractions per minute.
12 months
ICG clearance measured from hand using NIR ICG images. Unit of measure: (% difference Visit 1 from Visit 2)
2D still images collected from NIR scanning sessions will be analyzed to determine ICG clearance by comparing the % difference from visit 1 to visit 2.

NIR-ICG MRL
EXPERIMENTALWe may ask healthy subjects to return for up to four injection sessions for the study. The first injection session will consist of intradermal injection of ICG into the webspaces of the hand as done in our previous studies followed by NIR camera imaging. The second session will consist of intradermal gadolinium injection and intravenous (IV) iron contrast agent followed by MRI imaging approximately 1 week after the first session. The third session will occur at minimum eight weeks later and entail intra-articular ICG injection in order to evaluate drainage via the lymphatics. The MCP joints will be identified in the non-dominant hand and injected with ICG. Approximately one week later, the fourth session will compromise of intra-articular gadolinium injection and IV iron contrast to confirm lymphatic drainage. The MCP joints of the non-dominant hand will again be identified and injected with gadolinium.
Interventions
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.
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.
Eligibility Criteria
You may qualify if:
- Ability to provide written informed consent.
- Subjects must be 18 years old or older.
You may not qualify if:
- Active systemic disorders or inflammatory conditions (i.e., chronic infections with hepatitis B, hepatitis C or HIV) that would confound the study results.
- Known sensitivity to iodine because of residual iodide in indocyanine green
- Known sensitivity to gadolinium
- Any history of kidney disease
- Pregnant women should not participate; pregnancy tests will not be performed.
