What is the difference between a CT scan and a CT angiogram? What is the difference between a CT angiogram and a CT scan with IV contrast? An angiogram is a specific type ofCT scanwith contrast. In a CT angiogram the contrast is timed so that it will highlight either the arteries or ...
Conclusions: vContrast makes CT angiograms with inadequate contrast applicable for diagnostic evaluation, offering an improved visualization of the pulmonary arteries. In addition, vContrast can help in the significant reduction of the iodine contrast material....
Radiation dose reduction protocols allowed ACT to be comparable in exposure to a standard biplane cineangiogram. Conclusions Diagnostic-quality imaging can be obtained using ACT in 71% of cases without a significant increase in contrast or radiation exposure. In certain cases, ACT provides additional ...
Detection and delineation of suspected coronary anomalies in young persons (less than 40 years of age) with suggestive symptoms (e.g., angina, syncope, arrhythmia, and exertional dyspnea without other known etiology of these symptoms in children and adults; dyspnea, tachypnea, wheezing, periods of...
Diagnosis of ischemia-causing coronary stenoses by noninvasive fractional flow reserve computed from coronary computed tomographic angiograms. Results from the prospective multi-center DISCOVER-FLOW (Diagnosis of Ischemia-Causing Stenoses Obtained Via Noninvasive Fractional Flow Reserve) study. J Am Coll ...
Additional Contributions: We express sincere appreciation to the physicians who acted as volunteer readers of the FACTOR-64 coronary computed tomography angiograms, including Thomas R. Bonk, MD, Ritesh Dhar, MD, Todd D. Lovelace, MD, Christopher J. McGann, MD, Brent D. Wilson, MD, PhD, and...
(b) Axial CT angiogram reconstructed at the CT console immediately after the patient was scanned. The reconstruction was performed using the simple overlapping thick slab maximal intensity projection (MIP) algorithm and clearly shows (arrow) an occlusion of the proximal right middle cerebral artery (...
Contrast timing optimization of a two-volume dynamic CT pulmonary perfusion technique Article Open access 17 May 2022 Depiction of mosaic perfusion in chronic thromboembolic pulmonary hypertension (CTEPH) on C-arm computed tomography compared to computed tomography pulmonary angiogram (CTPA) Article Op...
ObjectivesMulti-modal imaging, mainly non contrast CT brain (NCCT) with CT angiogram (CTA) with or without CT perfusion (CTP) is essential for the rapid evaluation of stroke patients, with the ultimate goal being accurate diagnosis and timely management of patients.1 These imaging protocols are ...
4. As these diseases in human are clinically diagnosed with both non-invasive and invasive examinations including electrocardiogram, echocardiogram, magnetic resonance imaging (MRI), myocardiac perfusion scintigram, computed tomography (CT), cardiac angiogram and myocardial biopsy, these animal models have...
