Magn Reson Med Sci. 2021 Mar 1;20(1):106-111. doi: 10.2463/mrms.tn.2019-0167. Epub 2020 Feb 19.

Abstract

Not only magnetization transfer contrast (MTC) pulse, but also chemical shift selective (CHESS) pulse would be a useful additional one for shortening the scan time of neuromelanin imaging. We compared three sequences among turbo-spin echo (TSE) images with CHESS, MTC, and without an additional pulse in the same short time, 3 min 20 s. The TSE with CHESS image was the most useful for the diagnosis of neuromelanin within the limited time.

Keywords: chemical shift selective; magnetization transfer effect; neuromelanin imaging.
