Functional Imaging of Tumor and Normal Tissue

2014-08-26 22:21:00 | BioPortfolio


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.

Effectiveness in Head and Neck Cancer Detection Using Positron Emission Tomography (PET) Insert Device

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...

Identification and Characterization of Novel Proteins in Head and Neck Cancer

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...

Special Techniques in PET/Computed Tomography Imaging for Evaluation of Head and Neck Cancer.

PET with fluorodeoxyglucose F 18 (FDG)/computed tomography (CT) imaging has significantly improved the management of head and neck cancer. FDG, however, is not tumor-specific and various image interpr...

Simultaneous PET/MR head-neck cancer imaging: Preliminary clinical experience and multiparametric evaluation.

To evaluate the role of simultaneous hybrid PET/MR imaging and to correlate metabolic PET data with morpho-functional parameters derived by MRI in patients with head-neck cancer.

Vitamin E intake from natural sources and head and neck cancer risk: a pooled analysis in the International Head and Neck Cancer Epidemiology consortium.

Evidence for the possible effect of vitamin E on head and neck cancers (HNCs) is limited.

Establishment of a bioluminescence model for microenvironmentally induced oral carcinogenesis with implications for screening bioengineered scaffolds.

Microenvironmental cues play a major role in head and neck cancer. Biodegradable scaffolds used for bone regeneration might also act as stimulative cues for head and neck cancer. The purpose of this s...

Head and neck second primary cancer rates in the HPV era: A population based analysis.

Head and neck (H&N) cancer patients are at high risk for second primary malignancies (SPM). HPV-driven tumors are generally high-grade oropharyngeal cancers (OROhg). We analyzed the incidence of SPM o...

Medical and Biotech [MESH] Definitions

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.
