Improving Clinical PET/CT Image Quality in Retrospectively Reconstructed Breath-Hold Images

2014-08-27 03:14:12 | BioPortfolio


The patient has been referred for an FDG PET/CT scan. FDG is a form of sugar that contains a small amount of radioactivity; it is used to see the size and possible spread of cancer in the body.

Pictures of the body are taken on a machine called PET/CT scanner. The purpose of this current study is to see if we, the investigators, can take clearer pictures of the tumor than we could with our routine scan method. This would allow us to better see how FDG is picked up by the tumor. PET/CT is presently one of the best tools for the detecting cancer and determining its spread in the body. However, due to breathing motion, PET and CT images may become blurred and the location of the tumor on CT and PET images may not match. We have developed a new method that enables us to reduce image blurring and to measure the tumor more accurately on PET images. In this study we want to compare two images: the standard PET/CT scan, and the PET/CT scan pictures taken with our new method.

If successful, we may use this new method for clinical routine in the future.

Medical and Biotech [MESH] Definitions

Tumors or cancer of the LUNG.

Malignant neoplasm arising from the epithelium of the BRONCHI. It represents a large group of epithelial lung malignancies which can be divided into two clinical groups: SMALL CELL LUNG CANCER and NON-SMALL-CELL LUNG CARCINOMA.

A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.

Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control CELL PROLIFERATION and APOPTOSIS. A mutant or absent p53 protein has been found in LEUKEMIA; OSTEOSARCOMA; LUNG CANCER; and COLORECTAL CANCER.

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.
