ASNC

This channel contains news about the American Society of Nuclear Cardiology (ASNC), including coverage of its annual meeting and links to recently released practice guidelines. ASNC is a leading resource for the subspecialty of cardiac nuclear imaging (also called molecular imaging). Cardiac imaging with either PET or SPECT is primarily used for myocardial perfusion imaging (MPI), which shows area of areas of reduced blood flow due to ischemia or infarct.

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. The image shows how SPECT allows the reader to distinguish between blood pool activity and radiotracer uptake.

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 imnaging exam. Left if the black hole, right, is a similar nuclear imaging exam of the heart showing a similar ischemic perfusion defect to the black hole. Comparison of black hole photo to a cardiac exam.
