CAROTID STENTS: IMAGING PRE AND POST PLACEMENT

Joseph Polak

Diagnostic performance of carotid ultrasound in the NASCET and ACAS studies.

Results of the diagnostic accuracy of carotid ultrasound in the centers participating in the NASCET study published in 19951 showed that the sensitivity and specificity of carotid ultrasound were 68% and 67% respectively. The methodological issues that may have played a role include the following: variations in patient selection, in imaging device performance and variations in the imaging protocols1, 2, 3. The lack of a standard imaging protocol is believed to be the major reason for the poor diagnostic performance of carotid ultrasound in NASCET.
