Partial volume effect/artifact in Cross-Sectional MR Imaging

Partial volume effect/artifact is very common in cross-sectional imaging and occurs when portions of several objects are averaged together in a slice, resulting in impaired spatial resolution and erroneous signal intensity.
The main strategy for decreasing partial volume artifacts is to use smaller, more sharply-defined voxels. This means thinner sections, smaller fields-of-view, and/or higher imaging matrix sizes. Using longer duration RF-pulses (or at least avoiding “fast-RF” pulse options) will improve slice profiles and create more precisely defined voxels with less excitation of adjacent tissues.
