Summary
Magnetic eyelashes can cause significant artifact and detach in MRI scans. Radiologists and technologists should screen patients and staff for these cosmetic devices to ensure MRI safety.
Area of Science:
- Medical Imaging
- Radiology
- Biomedical Engineering
Background:
- Magnetic eyelashes are a novel cosmetic product.
- The interaction of cosmetic products with magnetic resonance imaging (MRI) environments is not fully understood.
- Patient safety in MRI is paramount.
Purpose of the Study:
- To evaluate the potential for magnetic eyelashes to cause artifact in MRI.
- To assess the risk of magnetic eyelash detachment within the MRI environment.
- To inform MRI safety protocols regarding cosmetic products.
Main Methods:
- A phantom was utilized to simulate the head within an MRI scanner.
- Magnetic eyelashes were applied to the phantom.
- The phantom with magnetic eyelashes was subjected to standard MRI sequences.
- Image quality and eyelash integrity were assessed.
Main Results:
- Substantial image artifact was observed in the presence of magnetic eyelashes.
- Detachment of magnetic eyelashes from the phantom occurred during MRI scanning.
- The observed artifacts could potentially compromise diagnostic image interpretation.
Conclusions:
- Magnetic eyelashes pose a significant safety risk in the MRI environment.
- Radiologists and MRI technologists must be aware of this potential hazard.
- Inclusion of magnetic eyelash screening on MRI safety questionnaires and screening systems is recommended for all individuals, including staff.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Direct current (DC) refers to an electric current that flows in a single direction, maintaining a constant polarity. This is in contrast to alternating current (AC), which periodically changes its direction and magnitude. AC forms the backbone of modern electricity transmission and distribution systems due to its efficient long-distance transmission capabilities.

Source transformation is a fundamental technique employed in circuit analysis, offering a valuable tool for simplifying complex electrical circuits. This technique involves the replacement of either a voltage source in series with a resistor by a current source in parallel with a resistor, or vice versa. The key concept here is that when the original sources are deactivated (turned off), the equivalent resistance at the circuit's end terminals remains the same.

Direct current is a flow of electric charge in only one direction and has a steady state of constant voltage in the circuit. Rectifiers, batteries, commutator-equipped generators, and fuel cells are some examples of devices that generate direct current. Nowadays, most applications use a time-varying voltage source. Alternating current is a flow of electric charge that periodically reverses direction. An alternating current is produced by an alternating emf that is generated in a power plant. If...

Laws form the essential rules set by governing authorities to shape and control societal behavior. In nursing, laws guide actions, safeguard patient rights, define nurses' scope of practice, and maintain professional standards. Understanding the legal framework governing nursing involves recognizing four primary sources of law: constitutional, statutory, administrative (regulatory), and common law.
