Non-Invasive Cerenkov Luminescence Imaging of Lymphoma, Leukemia and Metastatic Lymph Nodes
The purpose of this study is to see if a new way of imaging called the Cerenkov luminescence or effect that is used with a standard clinical PET/CT and/or investigation scans can be done in order to capture tumor sizes. The investigators believe endoscopies and surgical procedures could benefit from this type of imaging in the future. The Cerenkov imaging could be used as a guide for surgical resections.
The purpose of this study is to use the Cerenkov light from FDG, Iodine-131 tracer sand/or other investigational tracers to image tumors and its sizes in the head, neck, breast, axillary and pelvic regions with a highly sensitive camera. The investigators will be trying to see if we can get another picture of the tumor using the Cerenkov light as part of the standard clinical scan or therapy.

- feasibility of clinical Cerenkov imaging [ Time Frame: 2 years ]is to assess the feasibility of clinical Cerenkov luminescence imaging using current clinical radiotracers (18F-FDG and 131I) and a highly sensitive camera.
- Correlate Cerenkov imaging [ Time Frame: 2 years ]signal with uptake of the radiotracer. Cerenkov images will be correlated with images obtained from standard clinical PET/CT and scintigraphy.

pts receiving a PET/CT scan with Metastatic LNs
This study seeks to optically image the Cerenkov emissions from the PET tracer 18F-FDG and the radiotherapeutic 131I in a cohort of patients with primary tumor sites and from pathologic lymph nodes after routine 18F-FDG PET 31I radiotherapy and/or investigational study scans. We will include a subset of patients with normal lymph nodes during screening. This subset of patients will be imaged as a negative control for this study.
Radiation: Cerenkov emissions from the PET tracer 18F-FDG and the radiotherapeutic 131I
We will image (i) patients who are receiving a PET/CT scan for tumors in the head / neck region and (ii) patients with thyroid cancer after 131I radioablation. Two scans will be completed per patient, one of the primary tumors, as well as a 'background' scan of the contralateral side or, if tumor is there as well, of the forearm. The device to be used is an intensified charge-coupled device camera (Stanford Photonics, Palo Alto, CA) connected to a laptop PC. The camera will use a Quartz high-UV transmission 50 mm 0.8f lens. The Imaging device will be placed approximately 5 cm from the area of the patient to be imaged.
