Artifact from Eye Makeup

This is a 45-year-old woman who underwent MRI for headache.
Axial MR image demonstrates signal loss and image distortion of the anterior portions
of the eyes. Image distortion is more significant with gradient echo
(field echo) imaging compared with other sequences. 
 
Eye makeup, both mascara and tattoo eyeliner can cause image distortion and signal loss associated with the use of iron oxide or other metal-based pigments. Therefore, the patient should be advised to remove eye makeups before MR exam, if possible, particularly when indicated to evaluate for abnormalities in the brain and face.

Slight “tingling” and sensation of “burning” have been reported in subjects who wear permanent cosmetics, however, the frequency and severity of soft tissue reactions or other problems related to MRI and permanent cosmetics is unknown. Therefore, permanent cosmetics should not prevent patients from undergoing MRI. Decorative tattoo has higher chance to cause worse complication compared to cosmetic tattoo. Radiologist or technician should be informed that the patient wears permanent makeup or tattoos before the exam and possible complication and artefact should be discussed with patients.
