High spatial and temoporal resolution in magnetic resonance

Scientists developing instrumentation and techniques for in vivo imaging desperately try for both high spatial resolution and high temporal resolution for their devices. The former allows them to visualize small or weak objects more clearly and helps in quantification. The latter allows for the detailed study of dynamic processes. This post highlights two recent articles: Degen et al, PNAS, Jan 2009 and Weizenecker et al Phys. Med. Bio, 2009. The first article shows a technique of obtaining nanometer level spatial resolution for MRI. The second article shows first in vivo imaging results using real time magnetic particle imaging. Both articles are well written and demonstrate high grade science.
