Workshop Description:

Background:

Magnetic resonance imaging (MRI) is a key component of contemporary diagnostic imaging, known for producing comprehensive pictures of soft tissues, organs, and other interior structures. However, the existence of metallic implants, such as pacemakers, knee replacements, or dental implants, poses significant safety concerns. The powerful static magnetic field, as well as the time-varying gradient field and RF pulses utilized in MRI, might interact with these implants in potentially harmful ways. RF-generated heating can cause local tissue injury, whereas magnetically produced torque and displacement forces can cause mechanical displacement or implant failure. Additionally, the magnetic susceptibility of certain materials might distort MRI pictures, resulting in diagnostic inaccuracies. To safeguard patients and ensure accurate imaging, comprehensive research, and enhanced safety measures are required.

Goal/Rationale:

The major objective of this workshop is to address the complicated issue of implant safety in the MRI environment. This includes a thorough examination of the physical interactions between metallic implants and MRI systems, as well as the development of risk-mitigation measures. Recent advancements in MRI technology, such as optimized pulse sequences and a better knowledge of material characteristics, provide new opportunities for improving MRI safety. By bringing together a diverse group of experts from academia, healthcare, and industry, the workshop aims to:

  1. Identify and analyze the risks associated with RF-induced heating and magnetically induced forces.
  2. Develop and share best practices for minimizing these risks.
  3. Discover the most recent advances in implant materials and MRI technologies to
  4. improve MRI-implant compatibility and safety.
  5. Encourage collaboration to develop advancements in implant design and MRI safety standards.

Addressing these essential challenges would enhance patient outcomes, broaden the safe use of MRI for people with metallic implants, and advance the science of medical imaging.

Scope and Information for Participants:

The following main topics will be covered in this workshop:

  1. Metallic Biomaterials: Investigating the characteristics of various metallic materials used in implants and how they interact with MRI fields.
  2. MRI Pulse Sequences: Assessing modern MRI procedures including T1, T2 imaging, Spin-Echo, and Gradient-Echo imaging, as well as FLAIR sequences to reduce the dangers associated with RF pulses and gradient fields.
  3. RF-Induced Heating: Exploring the effects of RF pulses on implants and surrounding tissues, as well as techniques for mitigating these effects.
  4. Magnetically Induced Torque and Displacement Force: Understanding the forces generated by MRI fields on implants and creating strategies to forecast and mitigate these forces.
  5. Magnetic Susceptibility: Examining how implant materials affect the quality of MRI images and methods for minimizing artifacts.

Participants will gain insights into the latest research and technological advances in implant safety within MRI environments. The workshop will include presentations, case studies, and collaborative discussions, providing a comprehensive understanding of the challenges and potential solutions in this critical field.

Highlights

The workshop successfully addressed critical challenges and advancements in ensuring MRI safety for patients with metallic implants. Experts, researchers, and professionals from biomedical engineering and materials science convened to explore MRI technology, focusing on its physical principles and clinical imaging sequences, such as T1, T2, Spin-Echo, and Gradient-Echo. Detailed discussions examined the design and properties of metallic biomaterials, their interactions with MRI fields, and associated adverse effects, including RF-induced heating, magnetically induced forces, and image artifacts. Emphasis was placed on understanding these interactions to develop strategies for minimizing risks and enhancing patient safety. The workshop also highlighted MRI safety analysis protocols, including simulations to assess RF-induced heating and magnetically induced forces on implants, ensuring compliance with international safety standards. Case studies and collaborative discussions provided insights into advanced simulation techniques for evaluating implant performance and mitigating MRI-induced complications. The event achieved its goals of fostering multidisciplinary collaboration, advancing biomaterial design for improved MRI compatibility, and establishing best practices for MRI safety analysis. Participants left with a comprehensive understanding of current research and practical approaches to improve MRI protocols, enhance diagnostic accuracy, and broaden the safe application of MRI for individuals with implants.

Visitors who are not exempt from entry visa must obtain their visas or schedule an appointment with the Turkish Consular offices via Pre-Application System for Turkish Sticker Visa (www.visa.gov.tr). The applicants who meet the requirements will be directed by the Pre-Application System for Turkish Sticker Visa to the e-Visa system (www.evisa.gov.tr) In those countries where Türkiye does not have a consular representation can also use online scheduling for appointments with the nearest accredited consular office of Türkiye.

- In order to avoid inconveniences that may be caused by delays in processing, it is recommended to apply for visas at least one month in advance before the planned travel.

- The visas submitted to foreigners do not guarantee absolute rights of entry to Türkiye.

- Visa fees are not refundable in cases where applications are rejected.

- All applicants are required to have a medical insurance that will be valid during their stay in Türkiye.
