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.

The purpose of this study is to see if researchers can improve the detection of lung cancer by using a new method which will help us to take multiple snapshot images of the lungs while the...
This is a pilot study designed to to provide data and experience comparing two different techniques of breath hold SBRT treatments. The first technique will include SGRT, but with the assi...
Since 1996 proton therapy has been applied very successfully at the Paul Scherrer Institute in Switzerland to irradiate deep-seated, stationary tumors. In order to treat tumors within an o...
In this particular study the physicians want to use a new technique of how they obtain the PET/CT pictures. It is called "deep-inspiration breath-hold (DIBH) PET/CT". As the name suggests,...
This phase II trial studies how well deep inspiratory breath hold or prone breast radiation therapy works in reducing cardiac dose in patients with breast cancer or ductal carcinoma in sit...
The pathogenesis of predominantly neurological decompression sickness (DCS) is multifactorial. In SCUBA diving besides gas bubbles, DCS has been linked to microparticle release, impaired endothelial f...
To examine whether MRCP using a combination of compressed sensing and sensitivity encoding with navigator-triggered and breath-hold techniques (NT C-SENSE and BH C-SENSE, respectively) have comparable...
To clarify the clinical usefulness of breath-hold compressed sensing three-dimensional magnetic resonance cholangiopancreatography (BH-MRCP) added to conventional respiratory-gating MRCP (RG-MRCP), we...
This meta-analysis evaluates the difference in deep inspiration breath hold (DIBH) versus free breathing (FB) for patients receiving postoperative radiotherapy for left breast cancer and provides a us...
The aim of the study was to provide an evaluation of the oxygen transport, exchange and storage capacity of elite breath-hold divers (EBHD) compared with non-divers (ND).
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.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
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...
