Abstract

The embodiments of the invention provide a blood vessel analysis method and system. The blood vessel analysis method comprises the following steps that a peak period phase in a plurality of period phases is determined based on perfusion scanning data of the multiple period phases; image reconstruction is carried out based on the perfusion scanning data of the peak period phase to obtain a reconstruction result; and blood vessel analysis is carried out on the reconstruction result.

Description

technical field [0001] This specification relates to the technical field of scanning diagnosis, in particular to a blood vessel analysis method, system, device and storage medium. Background technique [0002] CT perfusion imaging reflects the blood supply of tissues and organs. Compared with ordinary CT plain scan and enhanced scan, which only collects data information at one time point, perfusion imaging obtains the blood supply of tissues or organs by continuously scanning multiple phases. The time-density curve (Time Attenuation Curve, TAC) of each voxel reflects the inflow and outflow process of the contrast agent in the tissue (blood perfusion), and then uses different mathematical models to calculate various perfusion parameters (such as cerebral blood flow). Volume CBF, regional cerebral blood volume CBV, mean transit time MTT, time to peak TTP, etc.), so as to form a perfusion parameter map, evaluate tissue ischemia, and guide the formulation of treatment plans. ...
