Dynamic contrast-enhanced (DCE) - magnetic resonance imaging (MRI), diffusion-weighted (DW)-MRI, and fludeoxyglucose - positron emission tomography - computed tomography (FDG-PET-CT) are three modalities that generate non-invasive, functional images of tumors and normal tissues based on physiologic properties including perfusion, vascular permeability and glucose metabolism. Demonstrating that these parameters are associated with clinical outcome, either efficacy or toxicity, could enhance the ability to select patients for different treatment strategies and improve the therapeutic ratio.
Patients will undergo functional imaging studies, DCE-MRI pre-treatment (twice) and after 1 week of Radiation Therapy (RT) and PET scans - pre-treatment and after 1 week of RT. Parotid gland saliva production will also be measured at baseline and at 3, 6, and 12 months of follow-up.

This pilot clinical trial studies how well whole-neck computed tomography perfusion scans work in imaging patients with head and neck tumors. Diagnostic imaging procedures, such as whole-n...
Through this study, we hope to learn more about the mechanisms, which may contribute to development and progression of head and neck cancer. The long-term goal of this study will be to de...
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...
Assessment of lymphatic structure and function pre- and post- treatment and during recovery in head and neck cancer related lymphedema patients using NIR fluorescence lymphatic imaging: Re...
The primary objective of this study is to describe, in detail, patterns of care for head and neck carcinoma patient
Head and neck cancer constitutes a substantial portion of the burden of disease in South Asia, and there is an undersupply of surgical capacity in this region. The purpose of this study was to estimat...
This study investigates cutoff scores for the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30-questions (EORTC QLQ-C30) and head and neck cancer-specif...
This article continues a series developed by the American Head and Neck Society's Education Committee entitled "Do you know your guidelines?" It is hoped that these features will increase awareness of...
Complete resection of head and neck tumors relies on palpation and visual inspection. Achieving a negative margin in remote locations in the head and neck region, especially in close proximity to crit...
Lymphedema frequently develops as a long-term effect from cancer and/or its treatment, including head and neck cancer (HNC). There is a substantial lack of understanding regarding the symptoms and exp...
Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck. (from Holland et al., Cancer Medicine, 4th ed, p1651)
Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
A form of RHABDOMYOSARCOMA arising primarily in the head and neck, especially the orbit, of children below the age of 10. The cells are smaller than those of other rhabdomyosarcomas and are of two basic cell types: spindle cells and round cells. This cancer is highly sensitive to chemotherapy and has a high cure rate with multi-modality therapy. (From Holland et al., Cancer Medicine, 3d ed, p2188)
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
A symptom, not a disease, of a twisted neck. In most instances, the head is tipped toward one side and the chin rotated toward the other. The involuntary muscle contractions in the neck region of patients with torticollis can be due to congenital defects, trauma, inflammation, tumors, and neurological or other factors.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
