“…When compared with cerebral contrast angiography, the accuracy of color Doppler sonography for diagnosing lesions causing less than 49% and more than 50% stenosis is in excess of 90%. 37 - 38 The accuracy of twodimensional time-of-flight magnetic resonance angiography is similar to that of color Doppler imaging.…”

Background and Purpose High-intensity transient signals detected by transcranial Doppler sonography have been associated with particulate cerebral emboli. Their clinical correlates are poorly understood. This study was undertaken to assess their relation to cerebral ischemia and to determine whether the severity of cerebral arterial stenosis has an impact on their occurrence.Methods We studied 96 arteries in 75 consecutive patients with extracranial or intracranial arterial lesions or potential cardiac sources of cerebral embolism. Sixty patients had histories of cerebral or retinal transient ischemic attacks or infarcts, and 15 were asymptomatic. The diagnosis of ischemia was based on the clinical presentation and was supported by extensive laboratory testing. A transcranial Doppler sonography unit equipped with special software for emboli detection was used. Signals were selected based on criteria established a priori.

“…Power Doppler imaging color-codes blood flow according to the amplitude of the Doppler signal. 77,78 These latter modalities afford greater sensitivity to blood flow detection, which allows improved detection of near-occlusive stenoses, tortuosity, and other morphological abnormalities in the arterial wall. 79,80 …”

“…In human medicine, ultrasound (US) examination has been widely used to estimate of the degree of stenosis and assess the echogenicity of atherosclerotic plaques deposited in the common carotid arteries (Sumner 1990). Physicians have relied on the echogenicity and echotexture of vessel walls to determine the soft tissue content and the amount of calcification deposited (Baroncini et al 2006).…”

RESUMO.-[Análise por histograma em escala de cinza para estudo da ecogenicidade e ecotextura das paredes das artérias carótidas comuns de equinos e muares.] A técnica de avaliação da ecogenicidade e ecotextura dos tecidos dos vasos sanguíneos por inspeção visual do exame de ultrassonografia, já é uma prática da rotina médica em humanos. No entanto, a simples visualização manual pode induzir à erros e diagnósticos de pouca qualidade. O uso ABSTRACT.-Fogaça J.L., Vettorato M.C., Puoli-Filho J.N.P., Fernandes M.A.R. & Machado V.M.V. 2019. Grayscale histogram analysis to study the echogenicity and echotexture of the walls of the common carotid arteries of equines and mules. Pesquisa Veterinária Brasileira 39 (3):221-229. Visual inspection of ultrasound examination for assessment of echogenicity and echotexture of blood vessel tissues is a technique routinely used in medical practice in humans. However, simple visual inspection can lead to poor quality diagnoses and errors. The use of grayscale histogram (GSH) analysis has proved to be an efficient technique to quantify the region of interest, allowing minimization of image interpretation errors. This study aimed to evaluate and compare the echogenicity and echotexture of the walls of the common carotid arteries of healthy female horses and mules using the GSH technique and correlate them with age, body mass, and vessel diameters. B-mode ultrasound examinations were performed in the left and right common carotid arteries in three regions (cranial, middle, and caudal) in 11 horses and 11 healthy mules. The GSH of the animals showed heterogeneous walls, but did not differentiate statistically between female horses and mules. The Mean variable of the middle right, middle left and caudal right sides showed differences, more significant in the mules. On the middle right side, the Min variable was different, higher in the mules. On the middle and caudal left side, the variables Max and Mode showed higher values in the mules. For the mules, the age factor presented negative correlation with the Mean, Mode,, Mode(Count), and Mode(Count)/Count(%) variables, and the body mass factor presented negative correlation with the Mode, Mean and Max variables. For the female horses, the body mass factor showed positive correlation with the Mean and Mode variables. Echogenicity of the carotid artery walls differed between female horses and mules, whereas echotexture was heterogeneous and statistically similar among the animals. The age and body mass factors inversely influenced the echogenicity of the mules, but were not significant in the female horses, in which only the body mass factor positively influenced echogenicity.
