HASTE/SS-FSE: Answers to Common Questions About This Fast MRI Sequence

Half-Fourier Acquisition Single-shot Turbo Spin Echo (HASTE/SS-FSE) is a T2-weighted technique using partial k-space sampling to reduce echo train length, enabling faster breath-hold imaging. It balances speed against potential blurring.

• Educational Q&A post explaining the HASTE/SS-FSE sequence from MRIQuestions.com.
• Covers how half-Fourier acquisition shortens scan time while preserving T2 contrast.
• Key limitation: potential loss of spatial resolution and increased SAR due to high flip-angle refocusing.
