Quick MR Neuromelanin Imaging Using a Chemical Shift Selective Pulse

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.
