Imaging the heterogeneity of the tumor microenvironment is thought to be valuable for assessing the efficacy of a cancer therapy. However, due to the insufficient resolution of clinically available molecular imaging tools such as positron emission tomography, this feat is currently not achievable. Here, we demonstrate that revealing the TME is possible with immuno-near-infrared-fluorescence (Immuno-NIRF) imaging. Moreover, we combined immuno-NIRF with optical coherence tomography (OCT) to provide structural context to the molecular images. The combination of the two techniques may represent a novel tool in the operating room for assessing development or early diagnosis of tumors.
