Overview

AHA/ASA guidelines recommend the routine use of non invasive imaging modality to localize the site of stenosis or occlusion as it may result in management alteration. Non invasive imaging modality for cerviocepahlic vessels include CT angiography and MR angiography. Invasive Imaging modality includes catheter angiography.^[1]

Other Imaging findings

Other imaging modalities may help identify the site of ischemia and underlying large or small vessel involved in patients with TIA. These imaging modalities include^[1]

Non invasive imaging modality

AHA/ASA guidelines recommend the routine use of non invasive imaging modality to localize the site of stenosis or occlusion as it may result in management alteration. Non invasive imaging modality for cerviocepahlic vessels include:

CT angiographying
MR angiography

Invasive imaging modality

AHA/ASS guidelines support the use of invasive imaging modality for confirmation of degree of stenosis determined by non invasive tests in selected patient groups. Invasive imaging modality which may be used include:

Catheter angiography
