These images were produced in yesterday's carotid artery duplex scan. They indicate some narrowing of the arteries - 20% of one and 40% of the other - but not enough to justify surgery. Angioplasty is a possibility. (See www.muschealth.com/gs/TandPcontent.aspx?pageid=P07992)
I need a bit of a tutorial on how to interpret these images. - probably there would be something on the web, but it would take time.
