An image analysis method is disclosed herein. The method includes the following operations: inputting a first image and a second image； extracting a plurality of first features of the first image and a plurality of second features of the second image； calibrating the first image and the second image according to the first features and the second features and generating a first calibrated image and a second calibrated image； calculating a first difference image of the first image and the second calibrated image and calculating a second difference image of the first calibrated image and the second image； utilizing an image analysis model to determine whether the first difference image and the second difference image are asymmetric and generating a symmetric result and an asymmetric result； and generating an analysis report according to the symmetric result or the asymmetric result.一種乳房影像分析方法，包含輸入第一乳房影像以及第二乳房影像；擷取第一乳房影像的複數個第一特徵以及第二乳房影像的複數個第二特徵；根據第一特徵以及第二特徵校正第一乳房影像以及第二乳房影像，以產生第一校準影像以及第二校準影像；計算第一乳房影像與第二校準影像的第一差異影像，以及計算該第一校準影像與該第二乳房影像的第二差異影像；利用影像分析模型分別判斷第一差異影像與第二差異影像是否對稱以產生對稱結果以及不對稱結果；以及根據對稱結果或不對稱結果產生分析報告。
