The U.S. Food and Drug Administration (FDA) issued a new draft guidance titled Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment.
Magnetic Resonance Imaging (MRI)
MRI creates images from the resonance created in hydrogen atoms when they are polerized and an electromegntic pulse is used to knock them off axis. This section includes MR analysis software, MRI scanners, gadolinium contrast agents, and related magnetic resonance accessories.

With the advent and optimization of nuclear scintigraphy protocols using bone-avid radiotracers, cardiac amyloidosis caused by transthyretin protein (ATTR) can now be diagnosed noninvasively without a costly tissue biopsy. The radiotracer 99mTc-pyrophosphate (99mTc-PYP) binds to deposited ATTR amyloid fibrils in the myocardium and can be visualized using planar and SPECT imaging. This is Figure 2, showing how SPECT imaging allows the reader to distinguish between blood pool activity (ventricular cavity, etc) and myocardial activity and identify regional myocardial differences in radiotracer uptake.
