Early assessment by CT/CT angiography helps predict recurrent stroke after TIA and minor stroke

CT/CT angiography can be a helpful diagnostic tool in predicting which patients who have experienced transient ischemic attack (TIA) and minor stroke are at highest risk of recurrent stroke, especially within the first 48 hours, according to a recent study by Canadian investigators.

Key Point: CT/CTA is a practical solution when MRI testing is not available for prompt assessment of patients with TIA and minor stroke to identify those at risk of recurrent stroke. Early identification and preventive treatment are key in these patients.

The assessment of TIA and minor stroke patients after the initial 24- to 48-hour window can miss those at highest risk, so it’s important to identify them quickly and treat them early to prevent another stroke. Due to its sensitivity and specificity, MRI has been the preferred diagnostic method for evaluating TIA patients, as noted in a 2009 scientific statement from the American Heart Association/American Stroke Association.

However, computerized tomographic angiography (CTA) is often more readily available than MRI, especially in less urbanized areas of...
