Abstract

The invention relates to a target artery selective marking method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a blood vessel positioning image of a target artery; determining a selective excitation pulse according to the blood vessel positioning image; marking according to the selective excitation pulse to obtain a perfusion map of the target artery. According to the method, the selective excitation pulse taking the artery as the target is designed on line through the selected artery position needing to be marked and based on a single-channel or multi-channel parallel emission platform, and the selective excitation pulse is applied to the marking section in the artery spin marking sequence, so that the effects of selectively marking the specific artery and obtaining the specific arterial perfusion map are achieved.

Description

Technical field [0001] The arterial marking technology of the present invention relates in particular to a target arterial selective marking method, apparatus, electronic device and storage medium. Background [0002] Traditional pseudo-continuous arterial spin label imaging (pCASL) usually labels all arteries flowing through the marker plane at once, so the collected perfusion map contributes to all arteries; In the clinical field, the perfusion map of a single artery has important clinical significance in the fields of stroke, arteriosclerosis evaluation, etc., so an arterial spin labeling method that selectively labels single or multiple blood vessels is required. [0003] In the prior art, the commonly used labeling method is based on the original pCASL sequence, an additional gradient in the horizontal direction is added between the adjacent two marker pulses, therefore, the phase difference caused by the additional gradient in the spatial position of the different horizonta...
