Growing number of patients with implants Audio filename: 03_implant_wbt_implantpatients More and more patients who need care for their specific health conditions are having implants. What is an implant? An implant is: surgically or medically inserted into the body made from materials like metal or plastic Implants serve various purposes: prosthesis diagnosis treatment ? What is an implant? Audio filename: 04_implant_wbt_definition An implant is a device surgically or medically inserted into the body to replace, support, or enhance biological structures. These devices, made from materials like metal or plastic, serve various purposes, from improving physical function to treatment. ? Types of implants Select the tab arrows for more information.

Safety labels for implants It is the responsibility of the implant manufacturer to categorize the safety of an implant. When a patient with an implant needs an MR scan, the very first step is to check the safety label of the implant. Please hover over the labels to learn about their definition. Unacceptable risk. Do not scan! No known hazards with MRI. It is safe to proceed with the scan. No known hazards in an MR environment under specific conditions of use. MR Unsafe MR Safe MR Conditional Safety labels for implants Audio filename: 08_implant_wbt_safetylabels Before scanning a patient with an implant, always verify its safety label. The implant’s manufacturer has conducted tests and simulations to categorize an implant and define its conditions and limits. If you can’t obtain information about the implant classification or its suitability for MR imaging at the field strength being used, consider this fact a contraindication for MR imaging. Please hover over the labels to learn about their definition. ? Where to get the information Here you can explore where to find the safety limits for an MR Conditional implant. If you cannot obtain information about the implant classification or its suitability for MR imaging, consider this a contraindication for MR imaging. Select the tab arrows for more information. Implant label Manufacturer’s guidelines Manufacturer’s website Where to get the information Audio filename: 09_implant_wbt_informationsources It is your responsibility to research and determine the safety limits of an MR Conditional implant as specified by the manufacturer. Please select the tab arrows for more information on where to look for these limits. Manufacturer’s website If you need more information, check the manufacturer’s website. Specific guidelines may be available to download. Implant’s labeling or packaging The implant’s labeling or packaging is the very first information source to look for. Manufacturer’s manual or guidelines The next source of information is the implant manufacturer's manual to check for guidelines regarding their MR Conditional implants. Please see the example guideline. ? Safety limits for MR Conditional Implants Safety limits for MR Conditional implants Audio filename: 10_implant_wbt_part2 In the second part of our training, you will learn about the essential safety limits for MR Conditional implants. ? When MRI meets the human body Ensure that defined parameter limits are met. They have to be entered during patient registration. Select the tab arrows for more information. RF pulses and heating SAR revisited Effective RF field (B1+rms) RF transmit mode (polarization) Operating modes in MRI When MRI meets the human body Audio filename: 11_implant_wbt_limits_general Before scanning a patient with an MR Conditional implant, you have to ensure that defined parameter limits are met and entered in the system. Please select the tab arrows for more information. Audio filename: 12_implant_wbt_limits_rfpulses RF pulses act as rapidly changing magnetic fields. They may induce electric currents in the body. These currents can heat the tissue. Moreover, an implant can cause a significant local temperature rise. Audio filename: 13_implant_wbt_limits_sar The Specific Absorption Rate measures how much RF energy is absorbed by the body. Please note that SAR does not mean the total amount of energy, but how fast it is absorbed. This is meant by rate: energy per time unit – which actually is power. Specific means, the RF power is measured per body mass. Audio filename: 14_implant_wbt_limits_b1plusrms B1+rms is another parameter that you must be familiar with. It represents the scanner’s effective RF field, which is lower than the peak value. This parameter is expressed as the root mean square value of B1 measured within a time frame. Before scanning, always check the implant's specifications for any B1+rms limitations. Audio filename: 15_implant_wbt_limits_transmitmode RF polarization refers to the orientation of the RF waves as they are transmitted. Linear polarization means, the RF waves oscillate in a single direction or plane. Circular polarization means, the RF waves oscillate in a rotating manner, forming a circular pattern. Audio filename: 16_implant_wbt_limits_operatingmode In MRI, operating mode refers to the safety and scan quality guidelines set by the International Electrotechnical Commission. These modes limit how much energy the body can absorb during an MRI. Operating modes in MRI Different operating modes result in varied SAR limits. Table with 3 columns and 3 rows Operating modes Normal No physiological stress Routine monitoring sufficient Default for most scans First-level controlled Higher levels of SAR May cause physiological stress Medical supervision required System must indicate first-level Operator must confirm RF transmit mode (polarization) Orientation of the RF waves: Linear, in a single direction Circular, in a rotating manner (most coils) RF polarization can lead to varying SAR levels. Therefore, choose appropriately. Linear polarization Circular polarization Effective RF field (B1+rms) The scanner’s effective RF field: Is lower than the peak value (rms = root mean square) Or quadratic mean Must not exceed the implant limit B1 peak B1+rms Time frame SAR revisited Specific absorption rate (SAR) measures: RF energy absorbed by the body Rate: Per time unit (energy / time = power) Specific: Per body mass Expressed in watts per kilogram (W/kg) Table with 2 columns and 4 rows SAR type Averaged over Whole body SAR Total mass of the body Head SAR Mass of the head Local SAR Any 10 g of tissue of the body RF pulses and heating RF pulses act as changing magnetic fields. This may result in: Electric currents in the body (alternating loops, see animation) Which in turn results in heating the tissue Implants can cause a significant local temperature rise. myExam Implant Suite Your guided interface for safe scanning: Enter specified values only once.

Describe implants and their classification An implant is a device surgically or medically inserted into the body to replace, support, or enhance biological structures. In MRI, implants are classified as MR Unsafe, MR Safe, or MR Conditional. For MR Conditional implants, adhere to the implant manufacturer’s safety conditions. They can be found on the implants packaging, the manufacturer’s guidelines, or on their website. Disclaimer Please note that the learning material is for training purposes only.
