Table 1 MRI system affecting PET

From: PET/MRI: a frontier in era of complementary hybrid imaging

Components of MRI Effect on PET Consequences Resolution
Static magnetic field (B0) Influences the ray of electron flow in read out. Lower gain factor. Substitute the Photomultiplier with Solid State Photo Detector (SSPD) such as SiPM or APD.
Gradient magnetic field (B1) Heats up the equipment leading to vibrations. Induction of eddy currents and mechanical vibrations. Restructuring of electronic components.
Fixing temperature control device.
RF Interference Introduces noise signal. Due to magnetic induction, introduces eddy current.
Produces heating effect.
Introducing RF shield around the coil.
