Among current modalities of biomedical and diagnostic imaging, MRI stands out by virtue of
its versatile contrast obtained without ionizing radiation. However, in various cases, eg,
water protons in tissues such as bone, tendon, and lung, MRI performance is limited by the
rapid decay of resonance signals associated with short transverse relaxation times T 2 or T
2*. Efforts to address this shortcoming have led to a variety of specialized short-T 2
techniques. Recent progress in this field expands the choice of methods and prompts fresh …
