Abstract
The purpose of this study was to compare image quality between compressed sensitivity encoding (CS) and sensitivity encoding (SENSE) in single-shot turbo spin echo diffusion-weighted imaging (TSE-DWI). Signal-tonoise ratios (SNR), apparent diffusion coefficient (ADC) values, and geometric accuracies were measured with an American College of Radiology head phantom. CS showed a high mean SNR, less variation in ADC values, and reduced imaging acquisition time (21.7 %-39.3 %) compared with SENSE. In addition, there was no significant difference in geometric accuracy between SENSE and CS. In conclusion, in comparison with SENSE TSE-DWI, CS TSE-DWI resulted in a reduced imaging acquisition time and improved SNR, while maintaining image quality.
