Triphasic Contrast Agent Injection in 64-MDCT Coronary Artery Angiography
Purpose: To evaluate image quality and cardiovascular enhancement after triphasic injection in 64-slice-CT coronary angiography (c-CTA). Methods: c-CTA of twenty-two asymptomatic patients following triphasic injection (65ml-contrast bolus + mixed 30mlcontrast and 20ml-saline bolus + 50ml-saline chaser) were retrospectively reviewed. Attenuation in the great vessels, cardiac chambers, and corona...
متن کاملHuge Coronary artery aneurysm Demonstrated by 64-slice MDCT Coronary angiography: a case report
Coronary artery aneurysm is an uncommon disease. We present a case of an unusual huge saccular coronary aneurysm of the left anterior descending coronary artery detected by 64-slice multi-detector computed tomography (MDCT) coronary angiography, which initially presented as a mediastinal mass on chest X-ray. The true size of the aneurysm would have been underestimated by coronary angiography be...
متن کاملCoronary-pulmonary artery fistula: value of 64-MDCT imaging.
A 57-year old previously healthy male presented following an episode of sudden-onset central chest tightness and syncope whilst driving. There was no prior history of such episodes. Baseline observations, physical examination, electrocardiograph and chest radiograph were all normal. Cardiac biomarkers were negative and transthoracic echocardiography revealed a structurally and functionally norm...
متن کاملEvaluation of Coronary Atherosclerotic Plaque Using Navigator Coronary MR Angiography with Reference to 64-MDCT Coronary Angiography
Introduction: Navigator coronary MR angiography (CMRA) with steady-state free precession (SSFP) demonstrated good diagnostic accuracy of assessing coronary significant stenosis [1], but evaluation of the modality in detecting coronary atherosclerotic plaques was not reported. The purpose of this study was to investigate the ability of navigator CMRA wih SSFP in detecting coronary plaque with re...
متن کاملArtifacts in ECG-synchronized MDCT coronary angiography.
OBJECTIVE In MDCT coronary angiography, image artifacts are the major cause of false-positive and false-negative interpretations regarding the presence of coronary artery stenoses. Hence, it is important that observers reporting these investigations are aware of the potential presence of image artifacts and that these artifacts are recognized. CONCLUSION The article explores the technical cau...
