Dual-phase DECT myocardial perfusion cuts time, dose
By Eric Barnes
There's no need to acquire images during both stress and rest phases in dual-energy CT (DECT) myocardial perfusion imaging, say researchers from the U.S. and Germany. A stress phase combined with a delayed-enhancement phase performs just as well while reducing radiation dose by a third.

MI is visible on nongated chest CT, but often missed
By Eric Barnes
General radiologists appear to be missing their chance to detect myocardial infarction (MI) during routine CT imaging. Researchers found that general radiologists prospectively detected fewer than half of MI on CT -- even though cardiac specialists found all of the cases when reviewing images after the fact.

Turf battles may be impeding growth of CCTA compared to MPI
By Kate Madden Yee
The use of coronary CT angiography (CCTA) has fallen faster than that of radionuclide myocardial perfusion imaging (MPI), and CCTA may be underused due to lack of referrals from cardiologists who control MPI equipment, according to a new study presented at the RSNA meeting earlier this month.
