CT联合征象及纹理分析在预测自发性脑出血血肿扩大中的研究进展

Review of CT sign combination and texture analysis in predicting hematoma enlargement of spontaneous intracerebral hemorrhage

血肿扩大(HE)是自发性脑出血(SICH)患者病情恶化及预后不良的独立危险因素,因此早期预测HE的发生具有重要临床意义。CT作为SICH患者首选辅助检查,其特征影像已被广泛应用于预测HE的发生,但其预测效能因征象单一及个人主观判断等因素影响而降低。为提高CT征象对HE的预测能力,多征象联合及基于CT图像的纹理分析成为当前研究新聚点。本文就近年来CT联合征象及纹理分析在预测SICH患者早期HE中的研究进展作一综述。

Hematoma enlargement(HE)is an independent risk factor for deterioration and poor prognosis in patients with spontaneous intracerebral hemorrhage(SICH),so it is of great clinical significance to predict the occurrence of HE in early stage.CT as the first choice of auxiliary examination for patients with SICH,its characteristic images have been widely used to predict the occurrence of HE,but its predictive efficiency is reduced due to single signs and personal subjective judgment and other factors.In order to improve the prediction ability of CT signs to HE,the combination of multi-features and texture analysis based on CT images have become a new focus of the current research.This article reviews the research progress of CT combined signs and texture analysis in predicting early HE in patients with SICH in recent years.
