Early stroke plain CT image evaluation system, evaluation method, and readable storage medium

Abstract

The invention provides an evaluation system, an evaluation method, and a readable storage medium for plain CT images in the early stage of cerebral apoplexy. The evaluation system includes a preprocessing module, a brain blood supply area segmentation module, a segment scoring module and a comprehensive scoring module, which can realize the processing of removing the skull and retaining the brain parenchyma on plain scan CT images, and matching the template image of the brain blood supply area. Align to the plain scan CT image, map several segmented blood supply areas marked by the template image of the blood supply area of ​​the brain to the plain scan CT image registered with it, and obtain several segments in the plain scan CT image For the blood supply area, the image performance of each segment blood supply area in the unenhanced CT image was scored, and the overall score of the unenhanced CT image was obtained. The evaluation system can assist doctors in the early diagnosis and treatment of stroke, can reduce the subjective differences of doctors, and help improve the efficiency and accuracy of diagnosis. The evaluation method and the readable storage medium have the same advantages.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an evaluation system, evaluation method, and readable storage medium for plain CT images in the early stage of cerebral apoplexy. Background technique [0002] Stroke is a major disease that seriously threatens the health of the population and hinders social and economic development. According to statistics, about 1.96 million people died of stroke in China in 2017. Compared with hemorrhagic stroke, the incidence of ischemic stroke is higher, accounting for 60% to 70% of the total stroke. There are more than 2 million new patients with acute ischemic stroke (AIS for short) every year in my country. One of the keys to the treatment of AIS is the time window. Early diagnosis can greatly improve the effect of treatment and rehabilitation, and some specific AIS treatment measures require case selection to select suitable patients for targeted treatment. Therefore, in the acute sta...

Problems solved by technology

However, in current clinical applications, experienced doctors often need to evaluate the plain CT images of the brain to obtain the early scores of stroke items, which is relatively subjective, and the difference between the lesion area and the normal area on the conventional plain CT images And the boundary of the blood supply area is difficult to directly observe with the naked eye. Usually, doctors only describe the plain CT images of the brain from the typical levels (tomography of the nuclei area and the area of ​​​​the nuclei area), which has low sensitivity and cannot achieve very high High diagnostic accuracy
