A cardiac computerized tomography (CT) scan – which can also be referred to as a coronary CT angiography or CT angiogram – is an imaging test to view the heart and blood vessels. It is a test that carries few risks and is less invasive than alternative procedures such as an angiogram....
The AHA report estimates that the negative predictive value of an ultrafast CT scan in these patients ranges from 90 % to 95 %, and suggests that a negative study may be useful in determining the need for further work-up with exercise stress testing and/or angiography. It must be realized,...
Most adult practitioners calculate estimated radiation dose from a cardiac CT scan by multiplying the scan DLP by a standard chest conversion factor. Calculating age and size specific radiation dose for CT scanning in pediatric patients is more complicated, and multiple methods are proposed [19, 20...
through the vessels of interest. In the current study, the bloodstream retention of PAA-Gd allows higher resolution angiography of long-scan-time sequences, such as BRAVO, which may be of great significance in the accurate diagnosis of microvascular diseases, especially for the micro-venous ...
The tiered cardiac CT protocol included a calcium scan, followed by CT angiography if calcium was detected. Patients with 鈮 50% stenosis on CT angiography underwent CT myocardial perfusion imaging. RESULTS: By 6 months, the primary endpoint, the rate of invasive coronary angiograms without a ...
CMR, cardiac magnetic resonance; CS, cardiac sarcoidosis; CT, computed tomography; FDG, fluorodeoxyglucose; PET, positron emission tomography. ∗ Consider performing CMR and FDG-PET scan to increase diagnostic yield, to assess for fibrosis and inflammation and to guide biopsy. Consider a CT scan ...
(CT), cardiac angiogram and myocardial biopsy, these animal models have also been evaluated by the same methods in previous studies5,6,7. However, since animal hearts especially in rodents are very small and heart rate is very high compared with human, some non-invasive examinations used for ...
Cardiovascular disease (CVD) is the leading cause of death and disease burden worldwide. Nuclear myocardial perfusion imaging with either single-photon emi
Current-generation 64-slice CT scanners have reduced con- cerns about radiation dose – mean radiation dose for one CCT is 1–2 mSv with appropriate scan optimization.56 Attaining 432 submit your manuscript | www.dovepress.com Dovepress Powered by TCPDF (www.tcpdf.org) Vascular Health and ...
Part I of this two-part series covered gastrointestinal causes of chest pain and aortic dissection. This second and final part of the series will focus on…
