WebBullets are solid or multilayered projectiles ejected by a gunpowder charge within a metal casing (shell). Solid bullets are typically made of lead or copper/zinc. Jacketed bullets have an external metal covering that can be steel, copper, or brass. Some bullets have a copper shell but a steel core. Others are copper and lead with a steel tip. WebAliasing is an important phenomenon in MR. It is the source of a common artifact (phase wrap-around) discussed in the next several Q&A's. Other types of aliasing artifacts include contamination of spectra from distant voxels in MRS and false measurement of flow velocities or flow direction in MRA.
