We have developed a prototype PET insert device that can be integrated into a clinical PET/computed tomography (CT) scanner to improve its image resolution to approximately 2.5 mm in all 3 dimensions within a reduced imaging field of view (FOV). This zoom-in imaging capability provides 6-fold improvement in volumetric image resolution over the current state-of-the-art clinical PET scanner, offering a tremendous opportunity for cancer imaging applications, in particular for those cases where a lymph node involvement will drastically alter the patient management plan. Accurate diagnosis and staging of head-and-neck cancer is known to be challenging because of the complex anatomy and large number of lymph nodes involved in this region. As a result, head and neck cancer imaging is an ideal candidate for evaluating the clinical usefulness of this novel imaging device.
In this project, we propose to conduct an exploratory clinical trial to investigate the effectiveness of this novel imaging device in detecting small lesions and lymph node involvements in the head and neck region, and compare its results to those obtained from a clinical PET/CT scanner. More specifically, we propose to (1) recruit 5 patients who have confirmed head and neck cancer and are scheduled to receive a whole-body PET/CT scan followed by surgical operation to remove the primary tumor and the regional lymph nodes. These patients will be imaged by a state-of-the-art PET/CT scanner using the standard whole-body PET/CT imaging protocol as standard of care for initial staging. On another day, following consent to participate in this research protocol, A patient will undergo images of the head and neck region using the same type scanner with and without our novel PET insert device attached; (2) The images obtained from the PET insert device will be reviewed by experienced nuclear medicine physicians to identify the extent of lymph node involvement. The PET insert images will be compared to the standard clinical PET/CT images. A detailed image obtained for purposes of research, centered at the level of the head and neck, acquired for approximately 3 times the length of time the standard clinical image is obtained for will also be compared to the PET insert image. Images will also be compared to the pathology report of the surgically removed specimen. (3) Estimate the performance of lesion detection for different sizes of tumors using the standard PET/CT scanner as well as the PET insert device.

Unusual tumor affecting any site of the body, but most often encountered in the head and neck. Considerable debate has surrounded the histogenesis of this neoplasm; however, it is considered to be a myoblastoma of, usually, a benign nature. It affects women more often than men. When it develops beneath the epidermis or mucous membrane, it can lead to proliferation of the squamous cells and mimic squamous cell carcinoma.
A carcinoma arising from MERKEL CELLS located in the basal layer of the epidermis and occurring most commonly as a primary neuroendocrine carcinoma of the skin. Merkel cells are tactile cells of neuroectodermal origin and histologically show neurosecretory granules. The skin of the head and neck are a common site of Merkel cell carcinoma, occurring generally in elderly patients. (Holland et al., Cancer Medicine, 3d ed, p1245)
A carcinoma derived from stratified squamous epithelium. It may also occur in sites where glandular or columnar epithelium is normally present. (From Stedman, 25th ed)
A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
A mixed adenocarcinoma and squamous cell or epidermoid carcinoma.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...

Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
