MRI has the advantages of having very high spatial resolution and is very adept at morphological imaging and functional imaging. MRI does have several disadvantages though. First, MRI has a sensitivity of around 10 −3 mol/L to 10 −5 mol/L, which, compared to other types of imaging, can be very limiting. This problem stems from the fact that the population difference between the nuclear spin states is very small at room temperature. For example, at 1.5 teslas, a typical field strength for clinical MRI, the difference between high and low energy states is approximately 9 molecules per 2million. Improvements to increase MR sensitivity include increasing magnetic field strength and hyperpolarization via optical pumping or dynamic nuclear polarization. There are also a variety of signal amplification schemes based on chemical exchange that increase sensitivity. [111] Heavey S, Costa H, Pye H, Burt EC, Jenkinson S, Lewis GR, etal. (May 2019).

Ongoing monitoring of the Earth's geomagnetic field (which includes the pole) will continue after the WMM release, principally through the European Space Agency Swarm mission, Korte said. But she noted that measuring the north magnetic pole's position is a challenge. That's because the pole is located in a remote area and the measurement of Earth's magnetic field is influenced by all magnetic-field sources — including the magnetic fields found in Earth's atmosphere (the ionosphere and magnetosphere).

MRI has a wide range of applications in medical diagnosis and more than 25,000 scanners are estimated to be in use worldwide. [24] MRI affects diagnosis and treatment in many specialties although the effect on improved health outcomes is disputed in certain cases.
