Objective of the current study was to obtain T 1 mapping of in vivo human breast using conventional 3D T 1 , T 2 and PD weighted images and comparing the results of with and without fat saturation. T 1 is an important parameter and its estimation is usually required during quantitative analysis, particularly during DCE-MRI data analysis. This simple approach, based upon conventionally acquired T 1 , T 2 and PD weighted images, provided absolute quantitation of T 1 in in vivo breast tissue. In the current study, we have shown that three data point (PD, T 2 and T 1 W) based approach for T 1 estimation works well for both with and without fat saturation.
