This week, cardiologists learned for the first time they have been examining black holes for decades and did not know it.
SPECT Imaging
Single-photon emission computerized tomography (SPECT) imaging is a nuclear imaging technology (also referred to as molecular imaging) that produces images showing how organs work.

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.

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.
