Pocket-sized device aids stroke diagnosis:
This article was originally published in Clinica
Researchers at the University of California at Los Angeles have developed a pocket-sized ultrasound device which could be used to aid the diagnosis of stroke. The device attaches to a stethoscope and measures blood flow in the middle cerebral artery within minutes of the patient's arrival at the emergency department. The Neurodop device had a sensitivity of 96% and specificity of 100% in trials on 53 cerebral arteries. Blood velocity could be determined to an overall accuracy of 81%. An estimation of the velocity of blood flow in the artery would markedly reduce the time to treatment in certain patients, the researchers said.
