Cardiac stress testing is used to determine to assess cardiac function and to disclose evidence of exertion-related cardiac hypoxia. Radionuclide testing using thallium or technetium can be used to demonstrate areas of perfusion abnormalities. With a maximal stress test the level of exercise is increased until the person's heart rate will not ...
Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
For all structures except the heart, the images are usually taken using a technique called digital subtraction angiography or DSA. Images in this case are usually taken at 2–3 frames per second, which allows the interventional radiologist to evaluate the flow of the blood through a vessel or vessels. This technique "subtracts" the bones and ...
In April 2013, the Journal of the American College of Cardiology published a study that relied on Life Line Screening data from a population-based screening study of more than 3.6 million Americans. Results showed the prevalence of peripheral artery disease (PAD) increased from 1 in 50 in the 40-to-50-year-old age group, to nearly 1 in 3 in the ...
Myocardial perfusion imaging or scanning (also referred to as MPI or MPS) is a nuclear medicine procedure that illustrates the function of the heart muscle (). [1]It evaluates many heart conditions, such as coronary artery disease (CAD), [2] hypertrophic cardiomyopathy and heart wall motion abnormalities.
Pneumonia and congestive heart failure are very commonly diagnosed by chest radiograph. Chest radiographs are also used to screen for job-related lung disease in industries such as mining where workers are exposed to dust. [3] For some conditions of the chest, radiography is good for screening but poor for diagnosis.
The Richard M. Ross Heart Hospital at The Ohio State University's Wexner Medical Center. The Ohio State Richard M. Ross Heart Hospital is located at Ohio State University in Columbus, Ohio. [1] The hospital specializes in cardiology, and is ranked number 46 in the United States for its heart program by U.S. News & World Report for 2020. [2]
Imaging of the cardiovascular system is usually performed with cardiac gating using an adaptation of conventional ECG techniques. [19] Cine sequences of the heart are acquired using balanced steady state free precession (bSSFP) which has good temporal resolution and intrinsic image contrast. T1-weighted sequences are used to visualize anatomy ...
