Purpose: To evaluate MRI artifacts at 3-Tesla for 38 commonly used cosmetics.
Materials and Methods: Thirty-eight cosmetics (16, nail polishes; 5, eyeliners; 3, mascaras; 10, eye shadows;
1, lip gloss; 1, body lotion; 1, body glitter, and 1, hair loss concealer) underwent evaluation for MRI artifacts
at 3-Tesla. The cosmetics were applied a copper-sulfate-filled, phantom and initially assessed using a
“screening” gradient echo (GRE) pulse sequence. Of the 38 different cosmetics, 14 (37%) exhibited artifacts.
For these 14 cosmetics, additional characterization of artifacts was performed using a GRE pulse sequence.
A qualitative scale was applied to characterize the artifact size.
Results: Artifacts were observed, as follows: 2, nail polishes; 5, eyeliners; 3, mascaras; 3, eye shadows; 1,
hair loss concealer. Artifact size ranged from small (eye shadow) to very large (hair loss concealer) and
tended to be associated with the presence of iron oxide or other metal-based ingredient.
Conclusions: Commonly used cosmetics caused artifacts that may create issues if the area of interest is the
same as where the cosmetic was applied or if its presence was unknown, thus, potentially causing it to
be construed as pathology. Therefore, these findings have important implications for patients referred for
MRI examinations.

1. Introduction
2. Materials and methods
Cosmetics, including eye makeup, nail polishes, body lotions,
hair loss concealers and others, are frequently used to improve or
enhance the appearance of the human body, without altering or
affecting the body's structure or function [1]. Several reports have
indicated that certain cosmetics, especially those containing iron
oxide or “heavy metal particles”, can produce unwanted artifacts
on magnetic resonance (MR) images [2–5]. Unfortunately, this
information has been limited to eye makeup (e.g., mascara, eye
shadow, and eye liner) and restricted to MR systems operating at
1.5 Tesla or less. Many other types of cosmetics may contain
ingredients that cause artifacts on MR images and it is well known
that artifacts are inherently larger in association with 3-Tesla MR
systems [6–10]. Artifacts may create issues if the area of interest is
the same as where the cosmetic was applied or if its presence was
unknown to the interpreting radiologist, thus, potentially causing it
to be construed as pathology [6,7]. Therefore, the purpose of this
investigation was to evaluate MRI artifacts at 3 Tesla for a variety of
commonly used cosmetics.

Thirty-eight commonly used cosmetics were selected for
evaluation in this study. Table 1 summarizes the information
(cosmetic type, name, brand, etc.) for the cosmetics that underwent assessment for artifacts, which included: 16, nail polishes; 5,
eyeliners; 3, mascaras; 10, eye shadows; and 4, miscellaneous
items (lip gloss, body lotion, body glitter, and hair loss concealer).
An effort was made to select those readily available items that
appeared to have metal-related components or “glitter” (22/38,
58%; Table 1). For example, of the sixteen nail polishes that
underwent testing, 13 (81%) contained glitter. For the 10 eye
shadows, 7 (70%) contained glitter. Both the body lotion and body
glitter contained glitter.
2.2. Sample preparation
Since each cosmetic that underwent testing is used on the surface
of the body, this evaluation of artifacts involved applying a sample of
each item to the surface of a copper-sulfate-filled phantom. Each nail
polish was applied twice to a 2.54-cm × 2.54-cm removable adhesive
square (Scotch Wallsaver Removable Mounting Square; 3M, St. Paul,

MN) and attached to the surface of the phantom for the assessment
of artifacts. The mascara, eye liner, eye shadow, lip gloss, body lotion,
and body glitter were applied to a 2.54-cm × 2.54-cm square area of
paper tape (Micropore Tape; 3M, St. Paul, MN) and attached to the
surface of the same copper sulfate-filled phantom, as indicated
above. The hair loss concealer was sprayed on a 5-cm × 5-cm piece
of white printing paper and allowed to dry for 4 hours. This paper
was then attached to the surface of a copper-sulfate-filled phantom
for the assessment of artifacts.
2.3. Determination of artifacts
In order to efficiently determine which of the 38 cosmetic
samples created an artifact at 3-Tesla, the cosmetics were initially
assessed using a “screening” gradient echo pulse sequence. The
following parameters were used, based on previous publications
and the artifact document issued by the American Society for
Testing and Materials (ASTM) International [8–11]: gradient echo
(GRE) pulse sequence; repetition time, 100-msec; echo time, 15-
K. Escher, F.G. Shellock / Magnetic Resonance Imaging 31 (2013) 778–782
msec; flip angle 30 o; matrix size, 256 × 256; section thickness, 10
mm; field of view, number of excitations, 2; bandwidth, 16 kHz.
The GRE pulse sequence was selected for this project because it
tends to have a great degree of artifact associated with it when MRI
is performed on a metallic object and, thus, it represents an
extreme MR imaging condition [8–11]. Section locations were
obtained through each cosmetic that were selected from multiple
“scout” MR images to identify possible artifacts as they were
presented in the largest or worst case situation.
For the cosmetics that showed artifacts, MRI was repeated using
the same pulse sequence as before (GRE; repetition time, 100 msec;
echo time, 15 msec; flip angle 30 o; matrix size, 256 × 256; section
thickness, 10-mm; number of excitations, 2; bandwidth, 16 kHz)
with the addition of selecting section locations through each cosmetic from multiple “scout” MR images to show the largest or
worst-case artifact size. The imaging planes were oriented to
encompass the long axis and short axis of each sample. The
frequency encoding direction was parallel to the plane of imaging.
The transmit/receive body RF coil (30-cm field of view) was utilized
for these MRI artifact assessments, with the exception of the hair
loss concealer, which used the transmit/receive head RF coil (26-cm
field of view). The transmit/receive head coil was used for the hair
loss concealer in order to simulate the conditions used if a patient
with this cosmetic was undergoing an MRI examination of the brain.
The image display parameters (i.e., window and level settings,
magnification, etc.) were carefully selected and used in a consistent
manner to provide valid representations of the artifact sizes [8–10].
While it is acknowledged that there are many possible MRI
parameters that may be used to evaluate artifacts, this particular methodology has been utilized in many previous reports involving the characterization of artifacts for implants, devices, and
materials [7–10].
A qualitative scale was applied to characterize the size of the
artifact associated with each cosmetic using a careful visual inspection by the investigator, as follows: (a) None, no artifact; (b) Small,
the artifact area was smaller than or the same size and shape of the
sample; (c) Moderate, the artifact area was 25 to 75% larger than
the size and shape of the sample; (d) Large, the artifact area was 76
to 100% larger than the size and shape of the sample; and (e) Very
Large, the artifact area was greater than 101% of the size and shape
of the sample.
3. Results
Table 1 summarizes the artifact findings for the cosmetics.
Artifacts were observed as areas of signal loss for 14 of the 38

cosmetics, as follows: 2, nail polishes (one with glitter); 5, eyeliners;
3, mascaras; 3, eye shadows (three with glitter); and 1, hair loss
concealer. Artifacts tended to be associated with the presence of iron
oxide or other metal-based ingredient. The artifact size ranged from
small (two eye shadows) to very large (baldness concealer). Figs. 1
and 2 show examples of MR images of the artifacts for the nail
polishes, eyeliners, and mascaras. Fig. 3 displays the MR image of the
artifact for the hair loss concealer, which exhibited the greatest
artifact size (i.e., very large) for the cosmetics that underwent
testing.
4. Discussion
Thirty-eight commonly used cosmetics were selected for evaluation in this study. An effort was made to select specific items that
appeared to have metal-related components or “glitter”. Although, it
should be noted that, glitter may be made from either small pieces of
metallic or nonmetallic materials including aluminum foil, iron
oxides, bismuth oxychloride, copolymer plastics, and other types of
materials. Interestingly, of the 22 cosmetics that contained glitter,

substantial signal loss that exists below the surface of the copper-sulfate-filled phantom.

only three (two nail polishes and one eye shadow) exhibited artifacts
on MRI.
Unfortunately, the information presented in the labeling of the
cosmetics with regard to the ingredients was somewhat problematic
insofar as there was often a statement that the particular makeup
“May contain….” certain compounds (e.g., iron oxide, iron dioxide,
titanium oxide, etc.) that may have been responsible for the artifacts
seen on MRI (Table 1). While every one of the cosmetics that showed
artifacts had a metal-related ingredient listed, we were unable to
obtain more accurate ingredient information that would have
otherwise permitted a prediction with regard to which cosmetic
was likely to cause artifacts.
4.1. Nail polishes
To our knowledge, this is the first description of MRI artifacts
found in association with nail polishes. Two out of 16 (12%) nail
polishes demonstrated artifacts that were moderate and large,
respectively. (Note: The nail polish that showed the large artifact
(Layla Magneffect) was designed to react to the magnet on the cap,
creating “three-dimensional designs in seconds”.) This information
is interesting because 13 of these were “glitter” nail polishes or
appeared to have a metallic appearance. Because the associated
artifact may disrupt the diagnostic use of MRI if the area of interest
is where the nail polish was applied (e.g., nail polish applied to toes
and an MRI is needed to evaluate the neuropathic foot in diabetes
mellitus), it would be prudent to thoroughly remove this cosmetic
prior to conducting the MRI examination.
doubtedly be unwilling to divulge the use of this product and surely
not aware of the artifact issue. Accordingly, if an MRI technologist
or radiologist observes a large signal void in a patient without a
neurological metallic implant undergoing MRI of the brain, the
possibility of hair loss concealer as being responsible for the artifact
should be considered.
5. Conclusions and recommendations
MRI testing performed on 38 commonly used cosmetics indicated
that artifacts can be associated with certain types of makeup
including nail polishes, eyeliners, mascaras, eye shadows, and even
hair loss concealer. The extent of the artifact may impact the
diagnostic use of MRI if the area of interest is the same as where the
cosmetic was applied or if its presence was unknown to the
interpreting radiologist, thus, potentially causing it to be construed
as pathology. Therefore, as part of the pre-MRI screening procedure,
consideration should be given to patient management with regard to
this information and a procedure should be in place to prevent issues
related to cosmetics. This may include advising patients before they
arrive for MRI exams to thoroughly remove all cosmetics.
Alternatively, it may be necessary to have makeup removal items
available at the MRI facility to take off different types of cosmetics
(e.g., nail polish remover). In the case of hair loss concealer, it is
necessary for the patient to wash the area with shampoo in order
to remove this product. Metal-based cosmetics may theoretically
cause issues for patients due to the potential for MRI-related
heating, however, that possible problem was not investigated
during our study.
4.2. Eyeliners, mascaras, and eye shadows
In the present investigation, each eyeliner (5/5), each mascara
(3/3), and three of the 10 eye shadows created artifacts at 3 Tesla.
The sizes of the artifacts ranged from small to large, which may
impact MRI of the orbital area but are unlikely to interfere with
routine head examinations because signal losses were localized to
the respective cosmetic's application area. In previous studies,
various types of eye makeup were reported to pose issues related
to artifacts on MRI [2–5]. In some cases, as indicated by Weiss et al.
[3], artifacts caused by eye makeup may mimic ocular disease such
as ciliary body melanoma or cyst. Accordingly, a patient undergoing
assessment of ocular or orbital regions should remove all forms of
eye makeup (eyeliner, mascara, and eye shadow) to prevent impairing the diagnostic use of MRI [2–5,12].
4.3. Miscellaneous cosmetics
For the miscellaneous cosmetics, only the hair loss concealer
produced an artifact, which was scored as “very large” in relation to the
size of the sample that was evaluated (Fig. 3). This unexpectedly
substantial artifact (probably related to the ingredients, “iron dioxides”) could compromise an MRI procedure involving the brain
due to the “depth” of the associated signal loss. While it would
be beneficial to identify a patient using this hair loss concealer
before performing MRI of the brain, such a patient would un-
