As the supply of the radiopharmaceutical tracer isotope technetium-99m dries up, cardiologists are exploring other options for cardiovascular imaging.

ASNC looks at how a variety of healthcare trends are positioning cardiovascular PET to thrive.

A randomized trial found that patients with suspected coronary heart disease who underwent cardiovascular magnetic resonance (CMR)–guided care had a significantly lower probability of unnecessary angiography within 12 months compared with patients who received National Institute for Health and Care Excellence (NICE) guidelines–directed care. The difference was not statistically different between CMR-guided care and myocardial perfusion scintigraphy (MPS)–guided care.
