“…First, the carotid artery is a large elastic vessel, whilst the intracranial arteries are mainly medium‐sized muscular vessels, and there are differences in anatomical structures. Secondly, both CIT and RIT were reported to be related to age, SBP and HDL‐C 8 ; however, there was no difference between the LAA and SVO subgroups regarding all the above‐mentioned parameters in this study. Thirdly, the pathologies in LAA and SVO are complicated, and atherosclerosis might contribute to both subtypes; the carotid artery is more vulnerable to atherosclerosis anatomically in nature and blood flow dynamics, leading to poor differentiating value of carotid parameters for the two groups.…”

“…Thickened CIMT has long been considered a marker of subclinical atherosclerosis. Previous studies and our recently published data have shown cross-sectional associations between CIMT and ischaemic stroke, 8,[10][11][12] and the value of CIMT in predicting cerebrovascular diseases. 13 However, the relationship between CIMT and stroke subtypes remains controversial.…”

“…Similar performance of RIT was noticed in our previous study. 8 In addition, RIT was reported as a predictor of adverse cardiovascular events, including stroke. 18 This indicates that RIT could be useful in diagnosis and outcome prediction of atherosclerosis‐related diseases.…”

“…The imaging modalities have been described previously. 8 Briefly, a 24‐MHz frequency high‐resolution linear transducer (PLI‐2004BX) connected to an ultrasound system (Aplio i900, Canon‐Toshiba Ultrasound, Tochigi‐ken, Japan) was used to scan carotid arteries, radial arteries and dorsalis pedis arteries for both left and right sides sequentially. Cine‐loops of at least three consecutive beats were digitally stored with an electrocardiogram simultaneously recorded.…”

“…Such a method could be used to anatomically predict atherosclerosis in the intima layer. 8 In this study, we aimed to differentiate LAA from SVO by applying the same 24‐MHz frequency high‐resolution ultrasound with the hypothesis that the intima layer is thicker in the LAA subtype than in the SVO subtype, and that it can be used to differentiate the two subtypes of ischaemic stroke.…”

Cerebrovascular disease is known to be responsible for significant morbidity and mortality worldwide. According to the 2018 World Health Organization Global Health Observatory data, ischaemic heart disease and stroke were the two leading causes of death globally, accounting for a combined 15.2 million deaths in 2016 (https://www.who.int/gho). The aetiologies of ischaemic stroke are heterogeneous. According to an aetiology-based classification criteria (Trial of Org 10172 in Acute Stroke Treatment, TOAST), stroke subtypes should be classified as large-artery atherosclerosis (LAA),small-vessel occlusion (SVO), cardioembolism, stroke of other determined aetiology and stroke of undetermined aetiology, 1 with the first two being predominant in China. 2,3 The pathologies in the different stroke subtypes are heterogeneous. Pathological changes in LAA include atherosclerosis, 4 which

BackgroundAcute stroke is the leading cause of death and disability globally, with an estimated 16 million cases each year. The progression of carotid stenosis reduces blood flow to the intracranial vasculature, causing stroke. Early recognition of ischemic stroke is crucial for disease treatment and management.PurposeA computer‐aided diagnosis (CAD) system was proposed in this study to rapidly evaluate ischemic stroke in carotid color Doppler (CCD).MethodsBased on the ground truth from the clinical examination report, the vision transformer (ViT) features extracted from all CCD images (513 stroke and 458 normal images) were combined in machine learning classifiers to generate the likelihood of ischemic stroke for each image. The pretrained weights from ImageNet reduced the time‐consuming training process. The accuracy, sensitivity, specificity, and area under the receiver operating characteristic curve were calculated to evaluate the stroke prediction model. The chi‐square test, DeLong test, and Bonferroni correction for multiple comparisons were applied to deal with the type‐I error. Only p values equal to or less than 0.00125 were considered to be statistically significant.ResultsThe proposed CAD system achieved an accuracy of 89%, a sensitivity of 94%, a specificity of 84%, and an area under the receiver operating characteristic curve of 0.95, outperforming the convolutional neural networks AlexNet (82%, p < 0.001), Inception‐v3 (78%, p < 0.001), ResNet101 (84%, p < 0.001), and DenseNet201 (85%, p < 0.01). The computational time in model training was only 30 s, which would be efficient and practical in clinical use.ConclusionsThe experiment shows the promising use of CCD images in stroke estimation. Using the pretrained ViT architecture, the image features can be automatically and efficiently generated without human intervention. The proposed CAD system provides a rapid and reliable suggestion for diagnosing ischemic stroke.
