This week, cardiologists learned for the first time they have been examining black holes for decades and did not know it.
PET Imaging
Positron emission tomography (PET) is a nuclear imaging technology (also referred to as molecular imaging) that enables visualization of metabolic processes in the body. The basics of PET imaging is that the technique detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (also called radiopharmaceuticals, radionuclides or radiotracer). The tracer is injected into a vein on a biologically active molecule, usually a sugar that is used for cellular energy. PET systems have sensitive detector panels to capture gamma ray emissions from inside the body and use software to plot to triangulate the source of the emissions, creating 3-D computed tomography images of the tracer concentrations within the body.

A comparison of the first-ever image of a black hole released this week by the Event Horizon Telescope collaboration et al. and a cardiac nuclear imaging exam. Left is the black hole, and right is a similar nuclear imaging exam of the heart showing a similar ischemic perfusion defect to the black hole.

SyncVision iFR Co-registration from Philips Healthcare maps pressure readings onto angiogram. Results from an international study presented at ACC 2019 indicates pressure readings obtained using iFR (instantaneous wave-free ratio, also referred to as instant wave-free ratio or instant flow reserve) in coronary arteries may localize stenoses that remain after interventions.
