MRI. can reveal bone bruises and fractures because these conditions cause . hemorrhage. within the bone that replace the normal marrow fat and thereby alters the MR signal. MR imaging does not show fractures line or fragments as well as CT because there is no MR signal from cortical bone.

The intensity of signal and thus image contrast can be modulated by altering certain parameters, such as interval between Rf pulses (TR) and time between Rf pulse and signal reception (TE). So-called T1-weighted (T1W) images are produced by keeping TR and TE relatively short.

Prechemotherapeutic, T1-weighted, axial magnetic resonance image in a 19-year-old man with B-cell lymphoma of the left humeral head shows a low–signal-intensity tumor involving the left humeral head (H). A soft-tissue mass surrounds the humeral head (arrowheads), with involvement of the glenohumeral joint (arrow). Enneking stage IIB.

Magnetic resonance imaging (MRI) of the equine distal limb has led to improvements in understanding of lameness pathogenesis. Until recently, MR imaging has been limited to the distal limb, but recently the use of MRI for clinical evaluation of the equine stifle has been reported. ...
