Motion Correction of Positron Emission Tomography (PET) Data Using Amplitude Gating
Evaluation of an amplitude based gated Positron Emission Tomography (PET) data acquisition system for all GE Discovery Positron Emission Tomography/ Computed Tomography (PET/CT) scanners.
Routine PET/CT scans are taken while patients are breathing normally. The motions made by breathing can reduce the image quality of the scan. Minimizing the effects of this motion by taking the images and processing the scans differently may improve the image quality.
The PET/CT Scan:
If you agree to take part in this study, an elastic belt will be placed around your lower chest/upper abdomen before your routine PET/CT scan. This belt is used to track your breathing motion. This information will be used to help process the scan.
Your PET/CT scan will be performed as usual. During the scan, researchers will focus on your lower chest/upper abdomen (areas that experience breathing motion). Having to focus on this area might extend the scan by up to 10 minutes.
The additional scan time will not increase your radiation exposure since only PET scanning will be performed.
Length of Study:
Your participation on this study will be complete when your scheduled PET/CT scan is complete.
This is an investigational study. The imaging focused on your lower chest/upper abdomen during the scan is investigational.
Up to 26 patients will take part in this study. All will be enrolled at M. D. Anderson.

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.
Tumor Suppressor Protein P53
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.
Carcinoma, Non-small-cell Lung
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 method of differentiating individuals based on the analysis of qualitative or quantitative biological traits or patterns. This process which has applications in forensics and identity theft prevention includes DNA profiles or DNA fingerprints, hand fingerprints, automated facial recognition, iris scan, hand geometry, retinal scan, vascular patterns, automated voice pattern recognition, and ultrasound of fingers.
CT-PET image fusion has the potential to differentiate 'tumor' from 'atelectasis' much better than the CT-scan in patients with non-small cell lung cancer who also have atelectasis....
RATIONALE: Imaging procedures, such as positron emission tomography (PET) scan and CT scan, may help doctors plan radiation therapy for patients with non-small cell lung cancer. PURPOSE:...
The purpose of this study is to compare the results of two CT scans of the chest performed within minutes of each other. We will compare several different measurements of lung cancer tumor...
RATIONALE: Radiofrequency ablation uses a high-frequency, electric current to kill tumor cells. Diagnostic procedures, such as PET scan and CT scan, may help doctors measure the patient's...
The trial evaluates the utility of 18FDG-PET/CT scan in the target definition process when SBRT is planned for stage I NSCLC.
We examined geographic patterns of lung cancer incidence in Kentucky. Recent research has suggested that the coal-mining industry contributes to lung cancer risk in Appalachia. We focused on the south...
Objective: [(18)F]Fluorodeoxyglucose positron emission tomography-computerized tomography (PET-CT) scan is a tool widely used in the diagnosis and staging of lung cancer. Referral bias is present when...
Lung cancer is one of malignant tumors harming human health. Over the past five decades, there is increasing morbidity and mortality of lung cancer which is the leading cause of cancer morbidity and m...
A 50-yr-old man presented with intermittent hemoptysis and was diagnosed small cell lung cancer. (18)F-FDG PET/CT for staging demonstrated extensive hypermetabolic lesions throughout the skeleton and...
PURPOSE: Lung cancers account for 5 % of second primary cancers after breast cancer. The low overall 5-year relative survival rate of lung cancer makes it a particularly concerning new malignancy for...
