EVALUATION OF MAGNETIC RESONANCE IMAGING UNDER THE INFLUENCE OF HAIR POWDER PRODUCTS
*Dr. Akio Ogura, PhD
ABSTRACT
Background: Commercial hair powder products are being increasingly used for purposes such as covering thin hair. As these products are often unnoticeable, magnetic resonance imaging (MRI) while using them may occur. As hair powder products may contain strong magnetic substances, they may scatter in MRI devices, possibly damaging the device. Purpose/Hypothesis: We conducted a physical evaluation about displacement force of magnetic fields induced by hair powder products from various manufacturers and related image artifacts aiming to evaluate their effects on MRI. Study Type (retrospective/prospectiveWhen hair powder contains a strong magnetic substance and MRI is performed under its influence, image artifacts occur, indicating possible damage to the MRI device due to powder scattering in the device caused by magnetic forces. The physical evaluation provided safety insights for MRI that may help prevent accidents and poor imaging when the device interacts with hair powder.
