Office Practice Assessment of Carotid Atherosclerosis Using Handheld Ultrasound (OPACA) Study

Study Overview
=================
Brief Summary
-----------------
The purposes of this study are to determine: Inter-site variability in CIMT image measurement using SonoCalcTM. If non-sonographer health care professionals working in an office practice setting can be trained to follow a carotid scanning protocol that permits (a) accurate measurement of CIMT and (b) determination of plaque presence. If (a) CIMT measurements and (b) determination of plaque presence by non-sonographer health care professionals are bioequivalent to those made by a core laboratory. If CIMT measurements and plaque assessment performed in office practices lead to meaningful changes in patient and physician behavior related to cardiovascular disease prevention.
