“…The demonstration of grossly detectable ferromagnetic characteristics of the tattoos and cosmetics has been described in various journals. 1,4,6,13 These cases have been manifested primarily as image distortion in the area of interest due to a nearby tattoo. MRI involves the use of a strong magnetic field to obtain images of structures within the body.…”

Tattoo-Induced Skin “Burn” During Magnetic Resonance Imaging in a Professional Football Player

The authors present the case of a professional football player with an immediate and sustained cutaneous reaction (“burn”) at the site of lower extremity tattoos that occurred during magnetic resonance imaging of the pelvis. The burn was attributed to an electromagnetic reaction due to the ferromagnetic metallic compounds found in tattoo pigments, especially iron oxide—a reaction that has the potential to distort the field of image. These compounds can theoretically create an electric current that increases the local skin temperature, enough to cause a cutaneous burn. “At risk” tattoos are those with black pigment or any other pigments containing iron oxide, as well as those with a design that displays loops, large circular objects, or multiple adjacent points. Patients who develop this reaction may be treated prophylactically or symptomatically with a cold compress to assist with completion of the examination. Alternatively, a towel or cloth may be placed between the cutaneous body parts in those patients who experience the typical reaction resulting from an electrical arc between 2 separate cutaneous tattoos. This is likely an underreported issue that merits mention in the sports medicine literature given the frequent occurrence of cosmetic tattoos in athletes requiring magnetic resonance imaging to diagnose a musculoskeletal injury. As in the present patient, no permanent sequelae have been noted in the literature. Therefore, patients who develop this reaction should be reassured that the reaction is only temporary.

“…The result is the appearance of a bigger, wider iris, which creates an illusion of large, doll-like eyes [1]. However, the extra-wide outer rim of the lens usually contains iron oxide, a known source of susceptibility artifact in MRI scans [3]. Indeed, the circle contact lenses showed susceptibility artifact consistent with extra-wide outer rim of the lenses in our in vitro case.…”

Incidental discovery of circle contact lens by MRI: you can’t scan my poker face, circle contact lens as a potential MRI hazard

BackgroundCircle contact lenses, also known as color contact lenses and big eye contact lenses, are a type of cosmetic contact lens. It is not generally known that a circle contact lens usually contains iron oxide and other metals, which means their use during magnetic resonance imaging (MRI) is a potential hazard.Case presentationWe present a rare case of incidental discovery of circle contact lenses by MRI and MRI images of circle lenses in vitro.ConclusionsCircle contact lenses usually contain iron oxide, which is a known source of susceptibility artifact on MRI. Not only radiologists and radiographers but also referring physicians should be familiar with the imaging findings and potential risk of scanning circle contact lenses by MRI.

“…Several p p m of dia-and paramagnetic substances have only a small effect on a magnetic field, whereas ferromagnetic substances have a 105 to 108 times stronger effect (Table 1) [2,4,5]. The artifact seen in the MR-images is produced by induction of a local field inhomogenity [1,4]. iron and nickel, less so chrome [6] have a strong effect on a magnetic field in a small concentation [3].…”

A semi-skeletted water-lodged corpse was supposed to be an 82-year-old missed man. Fifteen years ago this person underwent an operation of a trimalleolar fracture of the left ankle joint. Conventional X-ray photograms of the left ankle joint of the water-lodged corpse showed no evidence of an operation. A T-1 weighted spin-echo sequence revealed the entire aspect of the osteosynthesis as documented in the previously performed post-operative X-ray photograms.
