Brief Summary:
Cerebral blood flow measurement which is applied to patients with cerebrovascular-related diseases provides useful information about hemodynamic status There was a method using Doppler ultrasound and phase contrast PC MRI but it was not widely used in clinical practice due to limitations in reproducibility between examiners complexity of procedure and time-intensive protocol We intend to measure cerebral blood flow through the signal-intensity gradient SIG technique using Time-of-Flight TOF of brain magnetic resonance imaging which can compensate for the shortcomings of the existing research methods In addition by analyzing the correlation with the previous methods Doppler ultrasound and PC MRI we will evaluate the effectiveness of our new method
