Abstract

The invention provides a functional evaluation method and system for intracranial vascular stenosis, electronic equipment and a medium, and the method comprises the steps: carrying out the three-dimensional reconstruction of intracranial image data, and obtaining a three-dimensional model of a lesion blood vessel; acquiring specific blood flow parameters of the patient according to the three-dimensional model; calculating hemodynamic parameters of lesion blood vessels based on the patient-specific blood flow parameters; and according to the hemodynamic parameters of the lesion blood vessel, evaluating intracranial vascular stenosis. According to the functional evaluation method for intracranial vascular stenosis, the problem that the intracranial stenosis is inaccurately judged only through the intracranial liability artery stenosis degree in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to a functional evaluation method, system, electronic equipment and medium for intracranial vascular stenosis. Background technique [0002] Atherosclerosis is an important cause of ischemic cerebrovascular disease. The results of the CICAS study on intracranial atherosclerotic stenosis in China show that intracranial atherosclerosis accounts for 46.6% of ischemic strokes in the Chinese population, and the annual recurrence rate is as high as 19%. The high recurrence rate of stroke has become an important cause of disability and death in stroke patients. [0003] From a traditional point of view, the degree of stenosis of the responsible artery (such as diameter stenosis rate, area stenosis rate, minimum lumen area, etc.) has been used as the main factor to predict the recurrence of stroke patients. Obtained by comparing the narrowest diameter of the stenotic segment and t...
