Cardiac Calcium Scoring A computerized coronary tomography (CT) calcium scan is a heart test that scans the presence and quantity of calcium deposits in the arteries. Calcium deposits build up in the arteries narrowing the blood vessels, which may cause a heart attack or other heart illnesses. T...
The CTDI value, which is a basic radiation dose parameter of CT, can be measured and calculated as a mathematical integral under the radiation dose profile of a single rotation scan that would produce one tomographic image at a fixed table position. The CTDIvol represents the average radiation ...
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,...
[71]. This type of CT is recommended for the patients with low to intermediate risk of developing coronary artery diseases. This technique also has some limitations such as low specificity, ionizing radiation dose, and scan preparation, and the scan accuracy is found to get reduced in the ...
Patient Preparation and Scanning Sequence The absolute requirements for patients to undergo contrast-enhanced cardiac CT angiography include the ability to receive intravenous contrast and cooperate with breathing instructions and hold their breath for the duration of the scan (typically 10 seconds or less...
This review aims to provide a contemporary evaluation of the evidence for clinical use of FFRCT. The review article pays particular attention to the importance of patient preparation, anatomical features, scan quality and the overall interpretation of results that can lead to the best use of FFRCT...
Six participants (13%) had diffuse FDG uptake due to inadequate diet preparation. Interobserver agreement was high for presence of FDG uptake (κ = 0.95) and the number of FDG-positive myocardial segments (κ = 0.93). There was no significant difference in the proportion of patients...
Cardiac computed tomography (CT) integrated by electro-anatomical mapping was used for substrate identification and merged with dedicated CT scans for treatment plan preparation. A single 25-Gy radio-ablation dose was delivered by a LINAC-based volumetric modulated arc therapy technique in a non-...
Diagnosis/Preparation Before undergoing cardiac catheterization, the patient may have had other noninvasive diagnostic tests, including an electrocardiogram (ECG), echocardiography , computed tomography (CT), magnetic resonance imaging (MRI), laboratory studies (e.g., blood work), and/or nuclear ...
