Imaging

 

4D flow magnetic resonance imaging (MRI) offers striking visuals of blood flow in the heart and vessels but as yet has not found a foothold in clinical practice. Congenital heart disease, and in particular the bicuspid aortic valve, may provide its point of entry.

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.

Is a new testing strategy evolving for the evaluation of patients with stable chest pain?
