This is a prospective, open-label, multicenter, safety, comparative study of IV administered Tc99m-tilmanocept and unfiltered Tc99m sulfur colloid in the detection of and assessment of three dimensional tessellation localization to the liver in subjects with and without moderate to severe nonalcoholic steatohepatitis (NASH) by planar and SPECT/CT imaging.
This study is designed to evaluate the safety and tolerability of Tc99m-tilmanocept in subjects with NASH.

Experimental: Tc99m-sulfur colloid + Tc99m-tilmanocept
All subjects will receive a single IV injection of unfiltered sulfur colloid radiolabeled with 8 mCi Tc99m on study day 0. All subjects will receive a single IV injection of 200 mcg tilmanocept radiolabeled with 8 mCi Tc99m on study day 3.
Drug: Tc 99M Sulfur Colloid
Sulfur colloid is a radiotracer that is indicated for imaging areas of functional reticuloendothelial cells in the liver, spleen, and bone marrow.
Other Name: Sulfur colloidDrug: Tc99m-tilmanocept
Tilmanocept is a radiotracer that accumulates in macrophages by binding to a mannose binding receptor that resides on the surface.
