Why the study?
Can simple clinical features be used to identify patients with severe carotid stenosis on Doppler ultrasound in patients with acute stroke or transient ischaemic attacks?
Can simple clinical features be used to identify patients with severe carotid stenosis on Doppler ultrasound in patients with acute stroke or transient ischaemic attacks?
Simple clinical features alone or in combination do not have sufficient sensitivity and specificity to reliably identify severe carotid stenosis, reinforcing the need for routine carotid Doppler imaging in symptomatic patients.
No takes yet. Share an insight, caveat, or question.
Clinical features lack accuracy for selective imaging in stroke/TIA; leaves open whether multimodal models can safely reduce routine Doppler use.
Mead et al. (1999) studied this question.
