Parallel Imaging in MRI: An updated Q&A resource on accelerated acquisition techniques

A new educational Q&A resource from MRI Questions covers the physics, implementation, and artifacts of parallel imaging, providing clear, up-to-date explanations for radiologists and trainees to improve protocol optimization and image interpretation.

• Content type is an educational Q&A blog post, not a research study—numbers and statistical measures are not applicable.
• Explains fundamental concepts of PI including sensitivity encoding (SENSE) and generalized autocalibrating partially parallel acquisitions (GRAPPA) alongside common artifacts and SNR considerations.
• Limitation: This is a single-source educational website without peer review or systematic curriculum design.
