Nuclear Cardiology

Single photon computed tomography (SPECT) and positron emission tomography (PET) molecular imaging are used as primary cardiac imaging modalities to evaluate the function of the heart. It uses radioactive isotopes attached to sugars that are metabolized by cardiomyocytes. This creates an image of the metabolic activity of the heart and shows areas of ischemia or infarct. Other radiotracers can image the heart to diagnosis cardiac amyloidosis and sarcoidosis.

Cardiologist and ASNC president diagnoses the heart of the galaxy based on black hole imaging

The first image of the black hole at the heart of our Milky Way galaxy amazed the scientific community, but left cardiologists with questions about the true cardiac health of the galaxy.

The American Society of Nuclear Cardiology (ASNC) is asking Congress to repeal the appropriate use software provision mandate, which physicians say is an obstacle to efficient care.

Medical isotope update: Shortage expected to last weeks as nuclear reactor remains sidelined

Mo-99, Lu-177, and I-131 supply issues are forecasted until approximately one week after the downed reactor resumes operations on Feb. 12, the Nuclear Medicine Europe Emergency Response Team said.

Medical isotope shortage looms as 'unplanned' outage halts Mo-99, Lu-177 production

The root cause of the problem has not yet been discovered, halting isotope production for an undisclosed amount of time, according to SNMMI.
