Raisonance magnétique /
If the patient has metal implants, such as a prosthesis, it is possible to perform spin-echo sequences that are less sensitive to this artifact than gradient-echo sequences.
The use of non-ferromagnetic surgical material (titanium, platinum, aluminum, etc.) reduces these artifacts, but they still create inconspicuous hypersignal edgings.

Black boundary artifact, also known as India ink artifact or ***type 2 chemical shift artifact***...
This artifact occurs in gradient echo (GE) sequences as a result of selecting an echo time (TE) in which the fat and water spins (located in the same voxel at an interface) are out of phase, cancelling each other. At 1.5 T, the 3.5 ppm difference in frequency between water and saturated fat results in cancellation of spins at 4.5 ms multiples, starting at about 2.3 ms; for example at 6.8 ms, 11.3 ms, and 15.9 ms. This artifact does not occur with spin echo (SE) sequences as the spins are rephased by the 180o refocusing gradient.
