A rare incidence of metal artifact on MRI

Authors: Serkan Senol, Kazim Gumus

Abstract

We present a rare example of metal artifacts observed in magnetic resonance imaging (MRI). A 32-year-old male patient was referred to our radiology department for brain MRI. T1-weighted spin echo, T2-weighted turbo spin echo, diffusion-weighted, and fluid attenuated inversion recovery (FLAIR) images were acquired on a 1.5 Tesla scanner (Magnetom Aera, Siemens Erlangen, Germany). Unusual circular shapes resembling water bubbles were observed at the vertex on the conventional MR images (Figure 1). The patient was contacted if he had anything on his head, such as hair gel, etc. during MR imaging. It was found out that the patient was a metal worker who cuts metals and shapes things out of them and there were residual metal dusts on his scalp despite he had a shower before coming to the hospital.
