India ink artifact

The so-called india ink artifact also known as the black boundary artifact is an MRI feature seen on out-of-phase imaging and represents signal drop out in voxels that contain both fat and non-fat components. As such it is seen surrounding interfaces, lending the image an appearance as if someone has outlined these interfaces with ink.
