Abstract

The invention relates to a cerebral microhemorrhage quantification method and a computer readable storage medium. The method comprises the following steps: inputting an acquired brain magnetic resonance image into a brain region segmentation model to obtain a brain region segmentation result; inputting the brain magnetic resonance image into a cerebral microhemorrhage detection model to obtain a cerebral microhemorrhage area; determining a micro-hemorrhage quantification result of the brain area according to the brain area segmentation result and the brain micro-hemorrhage area; wherein the microhemorrhage quantification result is used for representing the number of microhemorrhage points in the brain area. According to the method, the microhemorrhage quantification result of the brain area is obtained through automatic processing of computer equipment, human participation is not needed, and the efficiency of the cerebral microhemorrhage quantification process is greatly improved; moreover, the neural network model is adopted to segment and detect the brain magnetic resonance image so as to obtain the micro-bleeding quantification result of the brain area, and the accuracy of the quantification result is further improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method for quantifying cerebral microbleeds and a computer-readable storage medium. Background technique [0002] Cerebral microbleeds (CMB) are microscopic cerebrovascular lesions that lead to the deposition of hemosiderin in the blood in the brain, which will damage the corresponding brain tissue and further cause cognitive dysfunction. At present, the severity of cerebral microbleeds is generally assessed clinically by the microbleed visual rating scale. The most common visual rating scales include microbleed anatomical rating scale (microbleed anatomical rating scale, MARS) and observer microbleed scoring scale. Table (brain observer microBleed scale, BOMBS); through the analysis of images of different brain regions, the microbleeds were divided into two categories according to the diameter of <5mm and 5-10mm, and then counted to evaluate the severity ...
