Nuclear Imaging
Nuclear imaging, also called molecular imaging, includes positron emission computed tomography (PET) and single photon emission computed tomography (SPECT) imaging. This section includes radiopharmaceuticals and tracers, PET-CT, SPECT-CT, and PET-MRI.

An example of a real-time patient radiation dose tracking system available for Canon's angiography imaging system. Systems like this can show cumulative dose to the patient's skin as a reminder to rotate the C-arm to new positions to prevent burns during long procedures. These types of systems also can help track patient dose and the location of that dose to be included as part of their electronic patient record. This data also enables quality assurance assessments.

A PET scan detects clumping proteins in rat hearts (top). The enlarged heart (right) is one with heart failure. Other PET scans showing blood flow in the rat hearts (bottom) show that the protein clumps aren't due to circulation problems. Image courtesy of Circulation Research, May 11, 2018.

A patient injured by extreme exposure to X-ray radiation during an angiography procedure, which is included among the images in the consensus document. Severe skin injury typically appears four to eight weeks following the exposure. In extreme cases, the ulceration can become confluent and full thickness necrosis of skin may develop, exposing underlying fat, muscle and even bone.
