General Advantages of Parallel Imaging
Parallel imaging provides several essential advantages for a multitude of MRI applications. The primary motivation for parallel imaging was faster imaging and MRI with higher spatial resolution; however, it soon turned out that parallel-acquisition techniques offer several other advantages as well such as improved image quality of single-shot MRI due to decreased blurring and reduced geometric distortions. In addition, MRI at high and ultra-high field strengths specifically benefits from parallel imaging, which ideally complements the increased SNR and compensates the growing specific absorption rate and increasing geometric distortions. Consequently, parallel imaging has been introduced in an ever-growing number of MRI protocols for an immense variety of clinical and research applications.
