The purpose of the study is to test a new amplified stethoscope(AudioDoc) that can detect
the presence of bruit by using an acoustic signal to represent the bruit. This pilot study
will address two questions: is there a detectable difference in recorded sound signal of
carotid and femoral bruit when compared to sound signals captured when there is no bruit
present; is the use of a visual recorded signal more accurate in identifying carotid and
femoral bruit when compared to traditional auscultation with a regular stethoscope and
ultrasound.

Recorded signals are stored on a laptop computer. The signals later undergo Fourier analysis
are then compared to the findings on carotid ultrasoud as to degree of stenosis. Subjects
with high grade stenosis in which no bruit was ascultated but in which carotid ultrasound
data suggests a bruit may be present are studied for soft /inaudible bruits. When available,
data will be correlated to CT/conventional angiographic studies.
