Ultrasound (US) techniques increase the ability of neurologists specializing in stroke to rapidly evaluate stroke patients, determine likely mechanisms of brain ischemia, determine arterial patency, quantify stenosis severity, and determine the most appropriate clinical management. Furthermore, the development of new US techniques based on the detection of US contrast agents may permit the evaluation of cerebral microcirculation and the identification of regions of angiogenesis, inflammation and thrombus during brain ischemia.

UI MeSH Term Description Entries
D008833 Microcirculation The circulation of the BLOOD through the MICROVASCULAR NETWORK. Microvascular Blood Flow,Microvascular Circulation,Blood Flow, Microvascular,Circulation, Microvascular,Flow, Microvascular Blood,Microvascular Blood Flows,Microvascular Circulations
D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
