A method of analyzing an MRI image is described. The method comprises the steps of: acquiring a first medical MR image and a second medical MR image of the subject at the same nominal magnetic field intensity; analyzing the first and second MR images to determine a wT1 map from the first and second images; applying a modified field intensity correction based on a nominal field intensity for the first and second MR image acquisition and an iron correction that corrects a difference in iron concentration from a normal level using the T2 * map to the wT1 map from the first and second images to generate a corrected wT1 map; an analog signal of a subject having a normal iron level is determined using the corrected wT1 map, and the analog signal is fitted to a standard cT1 to determine a standard cT1 image of the subject. An alternative method of generating a corrected wT1 map is also described. 描述了一种分析MRI图像的方法。所述方法包括以下步骤：以相同的标称磁场强度采集受试者的第一医学MR图像和第二医学MR图像；分析第一和第二MR图像，以从第一和第二图像确定wT1图；对来自第一和第二图像的wT1图应用基于用于第一和第二MR图像采集
