This is a randomised trial comparing early Cardiac Computed Tomography (CCT) to current standard practice for diagnosis of acute chest pain in patients at low to intermediate risk of having coronary artery disease (CAD), in a UK setting. We hypothesise that early CCT can reduce length of admission, reduce NHS costs and improve quality of life whilst being at least as safe as standard practice.
Protocol Title: Computed Tomography (CT) Guided Lung Biopsy with BioSentry Plug, Evaluation of Safety and Efficacy.
This is a prospective, randomized multicenter trial comparing MSCT to standard of care (SOC) diagnostic treatment in the triage of Emergency Department (ED) low to intermediate risk chest pain patients. Our hypotheses are that compared to SOC treatment, MSCT is equally safe and diagnostically effective, as well as more time and cost efficient.
The purpose of this study is to determine whether coronary artery computed tomography scanning is a more rapid, less expensive and safe alternative to standard diagnostic evaluation of patients with acute chest pain in the emergency room.
To compare the diagnostic performance and time efficiency of Computer-Aided Detection (CAD) assisted reading for the identification of pulmonary nodules in chest Computed Tomography (CT) from oncological patients with that of unassisted reading.
To investigate the relationship between coronary heart disease risk factors and coronary artery calcification in middle age adults from the Muscatine Study. From 1992 through 1995, ultrafast computed tomography was used to measure coronary artery calcification. The study has been extended through January, 2001 in order to examine the role of electron beam computed tomography in detecting the presence and quantity of coronary artery calcification, a marker of the atheroscleroti...
To determine whether, in a population of patients presenting to the rapid access chest pain clinic (RACPC), routine FFRct (Fractional Flow Reserve Computed Tomography) as a default test is superior in terms of resource utilisation when compared to routine clinical pathway algorithms recommended by the National Institute for Health and Care Excellence (NICE)
Currently patients with certain cancer usually have routine follow up (Computed Tomography of Thorax, Abdomen and Pelvis) CT TAP scans to see response to treatment or relapse. The study proposal allows the evaluation of the coronary arteries by modifying the current CT TAP technique without significant additional procedures, intravenous contrast or radiation - i.e. an opportunistic Computed Tomography Coronary Angiogram (CTCA) without any penalty. The question is does performin...
Traditionally, the physiotherapy management of people with dysfunctional breathing or hyperventilation syndrome is breathing re-training. There is increasing clinical evidence that structural and functional changes develop in the muscles and connective tissues of the chest wall, abdomen and back when the upper chest accessory pattern of breathing is used over time. When treatment includes breathing techniques only it is difficult for a person with chronic hyperventilation, who...
Breathing movements, called chest wall motion, are very complex. The investigators are studying how movement of the abdomen, ribs and diaphragm contribute to breathing and how this differs with different diseases in the chest. Breathing movements may help with diagnosis, assessment of severity or assessing the impact of treatments for chest conditions. The investigators are following people who have a chest disease, measuring their chest wall motion and comparing it to their di...
Open, Prospective Pilot Study to Obtain Aerosol Distribution in Asthmatic Patients Using Single Photon Emission Computed Tomography (SPECT) for Comparison With Functional Imaging Using Computer Methods
In this open prospective study, 6 well controlled asthmatic patients will undergo a high-resolution multi-slice computed tomography (CT) scan, lung function tests and a SPECT scan to obtain patient specific geometries of the central and peripheral small airways, patient specific boundary conditions and the in-vivo spatial distribution of inhaled aerosols.
The purpose of this study is to compare two methods of diagnosing coronary artery disease (CAD), thallium single photon emission computed tomography (SPECT) and ultrafast computed tomography (CT).
The primary aim of this study is to investigate the use of cone beam computed tomography (CBCT) for breast imaging in the diagnostic setting by providing a compelling body of evidence incorporating both non-contrast and contrast enhanced CBCT in the study protocol. The goal is to accumulate a body of evidence to provide data to incorporate CBCT into the diagnostic work-up of breast lesions.
Asthma is a disease resulting in mucus hypersecretion and airways obstruction. This causes difficulty breathing. The High Frequency Chest Compressor (HFCC) is a device that has been shown to decrease respiratory complications in individuals with severe disability who are unable to clear airway secretions. There is a lack of studies using this device in children with asthma. The device has been shown in a study to be safe in children with asthma. We propose that using this devic...
To compare results of Intravascular Ultrasound (which occurs during cardiac catheterization) with Computed Tomography (CT) scan to detect blockages or narrowing of the arteries that feed the heart. These will be studied in the cardiac transplant population.
The purpose of this study is to determine whether patient with ILD have altered lung compliance on chest CT before they have macroscopic structural changes on CT.
The primary objective of this study is to investigate the anti-angiogenic effect of bevacizumab measured by CTP as a predictive marker for efficacy measured by progression-free survival (PFS) in mCRC patients under first-line bevacizumab-containing, fluoropyrimidine-based chemotherapy
RATIONALE: Screening tests may help doctors detect cancer cells early and plan more effective treatment for lung cancer. It is not yet known whether helical computed tomography is more effective than chest x-ray in detecting lung cancer. PURPOSE: Randomized clinical trial to compare the effectiveness of helical computed tomography with that of chest x-ray in screening individuals who are at high risk for lung cancer.
The growing availability of cardiac computed tomography (CT)* in emergency departments (EDs) across the U.S. expands the opportunities for its clinical application, but also heightens the need to define its appropriate use in the evaluation of patients with acute chest pain. To address this need, we propose to perform a randomized diagnostic trial (RDT) to determine whether integrating cardiac CT, along with the information it provides on coronary artery disease (CAD) and left ...
This research study is being done because patients with a history of chest radiation treatment for Hodgkin's disease have been shown to be at increased risk for developing lung cancer a number of years out from treatment. The risk appears to be further increased among patients with a smoking history. Currently, the practice is to recommend annual low-dose chest CT scans in survivors of Hodgkin's disease who have received prior chest radiation treatment and who have at least a...
The aim is to compare a new technique for assessing mechanical properties of large arteries: the Ultrafast echo with the reference technique, the echotracking. This will be done by studying in parallel hypertensive patients and controls with both techniques and this will revisit old concepts of increased stiffness in hypertensive arteries.
RATIONALE: Comparing results of diagnostic procedures, such as computed tomography scan (CT scan), done before and after radiation therapy to help detect movement of the esophagus may help doctors plan the best treatment. PURPOSE: This clinical trial is using CT scan to help detect movement of the esophagus in patients undergoing radiation therapy to the chest.
To compare computed tomography (CT) images (pictures) of the coronary arteries using the General Electric (GE) LightSpeed VCT scanner with x-ray coronary angiography in patients with typical or atypical chest pain suspected of coronary artery disease (CAD).
The primary aim of this study is to continue the investigation of cone beam computed tomography (CBCT) for breast imaging already underway in the diagnostic setting by providing a compelling body of evidence incorporating non-contrast CBCT in the study protocol. The goal is to accumulate a body of evidence to provide data to incorporate CBCT into the diagnostic work-up of breast lesions.
This study will evaluate the effectiveness of a flexible belt device in guiding patient breathing during computed tomography (CT)-guided needle biopsy. When patients undergo CT scanning to help guide the physician during a tissue biopsy, they are usually asked to hold their breath while the scan is taken of certain parts of the body. When the first scan is completed, the patients are allowed to breathe, and are then asked to hold their breath again while the needle is advance...
