Prehospital Transcranial Ultrasound to Diagnose Stroke

Prehospital use of transcranial ultrasound to diagnose strokes is feasible, according to this paper. The study required stroke neurologists to rendezvous with paramedics on possible stroke calls and perform a physical exam and a transcranial ultrasound. The authors found a sensitivity of 78% and specificity of 98% diagnosing 73 strokes and 29 stroke mimics out of a total 232 patients enrolled.

The authors conclude, “Future combination with telemedical support, point-of-care analysis of blood serum markers, and probability algorithms of prehospital stroke diagnosis including ultrasound may help to speed up stroke treatment.”
