The cost of transcranial Doppler ultrasound ranges from $100 to $150, depending on the level of the hospital. Transcranial Doppler ultrasonography is a non-invasive testing technique that utilizes the weak part of the skull as the acoustic window for detection and applies the Doppler frequency shift effect to study the hemodynamics of the main stem of the basilar artery. Due to the advantages of real-time, portable, non-invasive, repeatable, and long-term monitoring, it has been widely used in clinical practice and plays an important role in the diagnosis of neurological diseases. The cost of transcranial Doppler ultrasound varies depending on the level of the hospital, for example, in secondary hospitals, the cost is around $100, while in tertiary hospitals, the cost is around $150. Professional physicians choose the appropriate examination method according to the patient’s specific situation, so if you have a need for examination, it is recommended to consult a neurologist.
