Quantitative analysis of continuous-wave Doppler spectral broadening for the diagnosis of carotid disease: Results of a multicenter study  K.Wayne Johnston, M.D., William H. Baker, M.D., Steven J. Burnham, M.D., Andrew C. Hayes, P.A., Cynthia A. Kupper, R.N., RVT,, Mary Ann Poole, R.N., RVT  Journal of Vascular Surgery  Volume 4, Issue 5, Pages 493-504 (November 1986) DOI: 10.1016/0741-5214(86)90386-1 Copyright © 1986 Society for Vascular Surgery and North American Chapter, International Society for Cardiovascular Surgery Terms and Conditions

Fig. 1 Continuous-wave Doppler spectral recordings. A, Normal recording. B, Abnormal recording distal to stenosis shows spectral broadening. Note that quality of the gray scale information has been lost in the photographic reproduction. SBI = spectral broadening index; AVPK = average peak frequency.

Fig. 4 Examples of plots of peak frequency and spectral broadening index (SBI) recorded from each of six recording sites. CC = common carotid artery; IC = internal carotid artery; EC = external carotid artery. A, Normal carotid artery. B, Internal carotid artery stenosis of 50%.

Fig. 5 Receiver operating characteristic curve for maximal peak frequency recorded from the internal carotid artery. Angiographic evidence of stenosis greater than 45% was considered a positive test. A 5 MHz probe has been used.

Fig. 7 Population distributions for peak frequency and the fitted polynomial equations. A, Normal (i.e., less than 45% stenosis). B, Abnormal (i.e., greater than 45% stenosis).
