YY/T 0987.3-2016 Translated English of Chinese Standard. (YYT 0987.3-2016, YY/T0987.3-2016, YYT0987.3-2016): Implants for Surgery - Magnetic Resonance Compatibility - Part 3: Evaluation of MR Image Artifacts from Passive Implants
https://www.chinesestandard.net, 2019 M03 5 - 13 pages
This Part of YY/T 0987 describes distortion and signal missing artifact triggered by passive implants (surgical implants that do not depend on electric energy or other energy for operation) in magnetic resonance (MR) image. Passive implants which cannot be determined as MR safe or MR conditional do not belong to the category of this Part.
