Abstract

The purpose of this project was to develop diffusion weighted periodically rotated overlapping parallel lines with enhanced reconstruction (DW-PROPELLER) on low-field open MR systems. The DW-PROPELLER was implemented on a 0.35T open MR system, and an auto pre-scan technique was used to mitigate non-Carr-Purcell-Meiboom-Gill (CPMG) artifacts. High quality diffusion weighted images and associated ADC maps were obtained. Multi-shot DW-PROPELLER is feasible for clinical use in the diagnosis of acute cerebral infarction on low-field open systems.
