Study on the Diagnostic Value of Mindray DC-75 Ultrasound in Cerebral Infarction Carotid Artery Stenosis
Objective:To analyze the application value of Mindray DC-75 ultrasound in the diagnosis of cerebral infarction carotid artery stenosis.Methods:81 patients with cerebral infarction related carotid artery stenosis admitted to our hospital from September 2020 to September 2023 were selected as the observation subjects,and 80 healthy volunteers were selected as the research subjects.The Mindray DC-75 ultrasound instrument was used to analyze the diagnostic accuracy(sensitivity,specificity,positive predictive value,negative predictive value),carotid artery plaques(single,multiple,no plaques),plaque distribution(carotid artery origin,carotid artery trunk,carotid sinus),and plaque classification(calcified plaque,fibrous plaque,lipid plaque,composite plaque)of the Mindray DC-75 ultrasound instrument.Results:81 cases of cerebral infarction related carotid artery stenosis were positive,while another 80 cases were negative;The Mindray DC-75 ultrasonic instrument detected 80 patients with cerebral infarction related carotid artery stenosis,with true positive,1 false negative,79 true negative,and 1 false positive.The sensitivity,specificity,negative predictive value,and positive predictive value of the Mindray DC-75 ultrasonic instrument were 98.7%,98.8%,98.8%,and 98.7%,respectively;The Mindray DC-75 ultrasound detected 22 cases(27.2%)of single lesions,37 cases(45.7%)of multiple lesions,and 21 cases(25.9%)of no plaques.The Mindray DC-75 ultrasound detected 25 cases(30.9%)located at the beginning of the carotid artery,34 cases(42.0%)located in the main carotid artery,21 cases(25.9%)located in the carotid sinus,15 cases(18.5%)of calcified plaques,21 cases(25.9%)of fibrous plaques,15 cases(18.5%)of lipid plaques,and 29 cases(35.8%)of complex plaques.Conclusion:Mindray DC-75 ultrasound instrument has a high diagnostic accuracy in cerebral infarction carotid artery stenosis,which can help clinical detection of plaque distribution,whether it is multiple,etc.Doctors can evaluate the disease condition according to the examination results of Mindray DC-75 ultrasound instrument,which plays an important role in the decision of follow-up treatment plan.
