Prediction model construction method and device, prediction method and device and electronic equipment

The invention relates to a prediction model construction method and device, a prediction method and device and electronic equipment, and the method comprises the steps: obtaining a first image feature of a region of interest of each brain perfusion image in a brain perfusion image set, wherein the region of interest comprises an abnormal region; screening out a second image feature meeting a preset condition from the first image features; obtaining survival features based on the second image features; and training a model based on the second image feature and the survival feature, and obtaining a prediction model for evaluating a prognosis state. The embodiment of the invention can improve the prediction precision of the prognosis state. 本公开涉及一种预测模型构建方法及装置、预测方法及装置、电子设备，所述预测模型的构建方法包括：获取脑灌注影像集内各脑灌注影像的感兴趣区域的第一影像特征，所述感兴趣区域包括异常区域；从所述第一影像特征中筛选出满足预设条件的第二影像特征；基于所述第二影像特征得到生存特征；基于所述第二影像特征和所述生存特征，训练模型，并得到用于评估预后状态的预测模型。本公开实施例可提高预后状态的预测精度。
