Unenhanced magnetic resonance imaging diagnoses osteonecrosis on the basis of loss of fatty marrow and the presence of edema. Enhanced magnetic resonance imaging, however, directly assesses marrow perfusion and allows earlier prediction of osteonecrosis after a bunionectomy.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
