Diffusion-weighted imaging of the head and neck with HASTE: influence of imaging parameters on image quality

摘要

Half-Fourier single-shot turbo spin-echo (HASTE) can be applied to diffusion-weighted (DW) imaging of the head and neck. However, HASTE DW imaging has certain drawbacks, such as severe blurring and low signal-to-noise ratio (SNR). The purpose of this study was to evaluate the influence of imaging parameters on image quality using phantoms. We also evaluated the discrimination ability of the apparent diffusion coefficient (ADC) in HASTE DW imaging to assess whether the technique is applicable to head and neck lesions.
