Usefulness of the three-dimensional computed tomography angiography in the control of clipped cerebral aneurysms presenting with subarachnoid hemorrhage [Valor de la angiotomografía tridimensional en el control post-clipaje de los aneurismas cerebrales que se presentan con hemorragia subaracnoidea]
(2010)
Introduction: Three-dimensional CT angiography (3DCTA) in diagnosis of cerebral aneurysms has replaced the invasive, but traditional catheter-based method of intra-arterial digital subtraction angiography (IADSA). This ...
Regional differences of fat depot attenuation using non-contrast, contrast-enhanced, and delayed-enhanced cardiac CT
(SAGE Publications, 2019-04)
Background: Regional fat density assessed by computed tomography (CT) has been suggested as a marker of perivascular adipose tissue inflammation. Dual energy CT (DECT) allows improved tissue characterization compared to ...
Beam hardening artifact reduction using dual energy computed tomography: implications for myocardial perfusion studies
(AME Publishing, 2015-02)
Background: Myocardial perfusion computed tomography (CTP) using conventional single energy (SE) imaging is influenced by the presence of beam hardening artifacts (BHA), occasionally resembling perfusion defects and commonly ...
Prognosis of Untreated Strokes Due to Anterior Circulation Proximal Intracranial Arterial Occlusions Detected by Use of Computed Tomography Angiography
(Amer Medical Assoc, 2014-02-01)
IMPORTANCE Limited data exist regarding the natural history of proximal intracranial arterial occlusions.OBJECTIVE To investigate the outcomes of patients who had an acute ischemic stroke attributed to an anterior circulation ...
C-reactive protein as a predictor of coronary events and coronary artery disease prevalence, extent, or severity by coronary CT angiography
(American Heart AssociationDallas, 2012-11)
Background: The association of C-reactive protein (CRP) with coronary calcium score, coronary artery disease (CAD) assessed by invasive angiography, and adverse coronary events has been studied with widely variable results. ...
Incremental prognostic value of coronary artery disease and renal function on the prediction of cardiovascular events of patients evaluated by coronary computed tomography: the partners registry
(American Heart AssociationDallas, 2013-11)
Background: Limited data exists on whether chronic kidney disease adds prognostic value after accounting for the presence and severity of coronary plaque. Therefore, we evaluated the incremental prognostic value of renal ...
