We excluded patients with transient ischemic attack or stroke mimics. The primary outcome was the proportion of patients with a thrombus on cardiac CT. Secondary outcomes were additional scan time, radiation dose, comparison with echocardiography, and 90-day outcomes. We performed logistic regression analyses to compare 90-day outcomes between patients with and without thrombus, adjusting for age, sex, history of atrial fibrillation, ischemic heart disease, chronic heart failure, stroke or transient ischemic attack, anticoagulant use, prestroke modified Rankin Scale score, National Institutes of Health Stroke Scale score, large vessel occlusions, and intravenous thrombolysis, as appropriate for each outcome.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      We included 3919 patients (median age, 74 [interquartile range (IQR), 63\u201382], 58% male, median National Institutes of Health Stroke Scale score 6 [IQR, 3\u201312]). Cardiac CT detected a thrombus in 243 (6.2%) patients. Among 1323 patients that underwent both cardiac CT and transthoracic echocardiography, cardiac CT had a higher yield than transthoracic echocardiography (odds ratio, 7.4 [95% CI, 4.0\u201315.1];\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;0.001). Median additional scan time was 6 minutes (IQR, 5\u20137) for ECG-gated and 13 seconds (IQR, 12\u201361) for non\u2013ECG-gated cardiac CT. Median additional radiation dose was 2.9 mSv (IQR, 1.6\u20134.1). Patients with thrombi had higher 90-day mortality (33% versus 15%, adjusted odds ratio, 1.6 [95% CI, 1.1\u20132.3]) and worse modified Rankin Scale scores (median modified Rankin Scale score 3 versus 2, adjusted odds ratio, 1.6 [95% CI, 1.2\u20132.0]), but similar recurrent stroke rates (5% versus 4%, adjusted odds ratio, 1.4 [95% CI, 0.7\u20132.5]).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>Implementing cardiac CT into the acute stroke imaging protocol is feasible, detects thrombi in \u22486% of patients, and has a higher yield than transthoracic echocardiography.
