The experts address: (1) the usefulness of CT scans to provide additional information for more accurate patient risk stratification, (2) safety and risk of CT scan radiation exposure, (3) the use of CT scans for patient adherence to medication guidelines, (4) the cost of CT scans and ...
There have been no data with regard to the relationship between coronary artery calcification (CAC) detected with positron emission tomography (PET)/computed tomography (CT), as incidental findings, and myocardial perfusion single photon computed tomography (MPS) results in patients with cancer.The mai...

Instead, a more accurate risk assessment using coronary artery calcium (CAC) testing is available; and has just been adopted by ACC/AHA guidelines, however payers do not cover it. CAC is measured non-invasively with a 5-minute CT-scan of the heart, and costs less than $200, whereas ...
a declining tendency were showed with further increasing of age.Conclusion The CAC screening in doing pulmonary CT un contrast enhanced scan in health examination is possible,and it can also be used in valuing the clinical significance of finding out CAC in the clinical diagnose of coronary ...
PURPOSE: To prospectively compare the results of coronary artery calcium (CAC) measurements obtained with 55- and 165-mAs electrocardiographically gated multi-detector row computed tomography (CT). MATERIALS AND METHODS: Institutional clinical study review board approval and written informed consent were ...

Background: Multidetector CT allows detection of coronary artery calcium and, after contrast injection, visualisation of the coronary artery lumen. It is commonly assumed that the absence of coronary calcification makes the presence of obstructive coronary lesions highly unlikely. This study evaluates the...
There are 2 different types of coronary CT scans: a coronary CT angiogram and a coronary artery calcium scan. Both tests take place inside a standard CT scan machine, but there are important differences between them. What Are the Potential Benefits of a Coronary CT Scan?
have been used to establish ECG-triggered or ECGgated multislice CT (MSCT) examinations of the heart and the coronary arteries in clinical use (6–10). As a result of the increased scan speed with four simultaneously acquired slices, coverage of the entire heart volume with thin slices within...
