<meta name="DC.Description" content="PURPOSE To describe fat-suppression failure artifacts and to caution against their misinterpretation.

METHOD Magnetic-susceptibility artifacts were studied in a phantom model and the results were compared to MR images obtained in clinical cases.

FINDINGS Artifacts manifested themselves as regions of focal fat-suppression failure and appeared as bright signals without geometric distortions at magnetic-susceptibility interfaces along the static field (z) direction. The location and extent of these artifacts were independent of either frequency or phase-encoding direction and are different from those observed in gradient-echo images.

CONCLUSIONS In representative clinical MR exams, these artifacts were identified in the high nasopharynx and low orbit and should not be misinterpreted as pathology." />
