Interobserver and intraobserver reliabilities of multislice electrocardiogram-gated spiral computerized tomography in evaluating aortic atheroma in patients with acute ischemic stroke

Ischemic Stroke: Etiologic Work-up with Multidetector CT of Heart and Extra- and Intracranial Arteries

“…Multidetector CT may also yield information regarding plaque composition, including calcification and plaque attenuation characteristics, both which may be of interest in the assessment of vulnerable plaques ( 23 ). Furthermore, multidetector CT has been demonstrated to be effective and reproducible in the detection and quantifi cation of aortic arch atheroma ( 24,25 ). In the identifi cation of cardioembolic etiologies, Hur et al ( 10 ) achieved a sensitivity of 89% and a specifi city of 100%.…”

Cerebral Infarction Due to Aortic Mural Thrombus in a Non-atherosclerotic Ascending Aorta, Detected by Cardiac CT

“… 12) Furthermore, an investigation of 46 cryptogenic stroke patients found that all 9 cases of aortic lesions detected with TEE were properly identified with cardiac CT. Indeed, Pandya et al 13) reported that cardiac CT could be used to detect CAAs with good reliability. The greatest advantage cardiac CT is that, unlike TEE, the examination is non-dependent to the examiner.…”

Comparison of Computed Tomography Angiography and Transesophageal Echocardiography for Evaluating Aortic Arch Disease

“…44 More recently, cardiac CT has been used to detect AA atheromas with reliability. 31,45 Magnetic resonance (MR) technology, including 3-dimensional gadolinium enhanced images combined with breath-holding, cardiac-gated MR, and more recently 3-T MRI, has been investigated for detection of AA atheromas. 23,46,47 Although MR imaging may provide more detailed visualization of AA atheromas, these MR-based techniques have been shown to either overestimate or underestimate plaque size compared with TEE.…”
