Synopsis

Synthetic images can be generated from quantified tissue properties (T1, T2, proton density) to mimic conventional MR images. Synthetic images require quantitative information, ideally from a multiparametric scan. As multiparametric MRI becomes more rapid, robust and accurate, the opportunity to reduce scan time and gain information by combining quantitative maps with synthetic images is more widely available. Techniques such as, MR fingerprinting (MRF) and multidynamic multiecho (MDME) are examples of rapid quantitative imaging that can be used to calculate synthetic images. Applications to various diseases show that synthetic imaging can be comparable in quality and diagnostic information to conventional images.

In this talk, we will consider the differences between conventional weighted MR images and synthetically generated images. To calculate synthetic images, we must consider the multiparametric quantification methods of MRI first, and will focus on examples of MR fingerprinting (MRF) and multidynamc multiecho (MDME) sequences. Examples of partial volume and segmentation using these method will also be shown.
