PHOSPHORUS MAGNETIC RESONANCE IMAGING

摘要

Information relating to the distribution of phosphorus nuclei within an object, such as a bone, is obtained by applying to the object a magnetic field and also a series of RF electromagnetic pulses (104). After each pulse (104) magnetic field gradient pulses (106x, 106y) are applied to the object, and RF signals (105) emitted by the nuclei are acquired during a period when a magnetic field gradient pulse (106x, 106y) is rising to a maximum and remaining at a maximum value. The acquired signals are processed to obtain information relating to the distribution of phosphorus nuclei despite the very short spin­-spin magnetic relaxation time (T2) of phosphorus.
