MRI of fast-relaxing spins

Research output: Contribution to journalArticlepeer-review

21 Scopus citations


MR imaging of extremely fast-relaxing spins is currently a topic of much interest due to recent technical innovations and groundbreaking studies demonstrating its utility in biomedical research applications. From a technical perspective, this article examines the different classes of pulse sequences currently available to image spins with ultra-short transverse relaxation times (T2 and T2), with particular attention focused on the newest member of the class, sweep imaging with Fourier transformation (SWIFT).
